Getting started:

1. Download EasyPhpThumbnail and upload the example directory to your webserver
2. Upload the class (PHP4 or PHP5 version) to the 'inc' example directory
3. Open the example.php page in your browser

This will display a resized thumbnail. You can edit the example.php file and try one of the many examples.

The most simple example script would be:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Createthumb('gfx/image.jpg');
?>




This would create a thumbnail with the standard settings and send the result to the browser (dynamic or on-the-fly thumbnail generation).

Note: If you are going to access the class from various pages on your website, make sure you always pass the full path to the image.

If you want to integrate the thumbnail on a webpage, you have to use a dynamic image. Create a separate PHP file called for example 'thumbnail.php' and add your code there:

<?php
if (isset($_REQUEST['thumb'])) {
 include_once('inc/easyphpthumbnail.class.php');
 // Your full path to the images
 $dir = str_replace(chr(92),chr(47),getcwd()) . '/gfx/';
 // Create the thumbnail
 $thumb = new easyphpthumbnail;
 $thumb -> Thumbsize = 300;
 $thumb -> Createthumb($dir . basename($_REQUEST['thumb']));
}
?>


Then on your page where you need the thumbnail add a link to the image like (save this sample as photo.php):

<?php
$file='image.jpg';
echo "<img src=\"thumbnail.php?thumb=$file\" alt=\"thumb\" />";
?>


The directory structure in the above example would be: inc which includes the class, gfx for the images (needs to contain a file called 'image.jpg') and the files photo.php and thumbnail.php. Open the file 'photo.php' in your browser to see the result.The example above would show a larger thumbnail by using the 'Thumbsize' parameter:



Writing the thumbnail to file:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Createthumb('gfx/image.jpg','file');
?>


For batch creation of thumbnails you can pass an array with filenames:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Createthumb(array('gfx/image.jpg','image2.jpg','image3.jpg'),'file');
?>


Alternatively you can pass filename by filename allowing you to customize some options per image. In the example script below every image in the working directory is converted to JPG format and saved in the subdirectory 'gfx/thumbs/'. In addition the thumbnail files are renamed with prefix '120px_thumb_' and chmod-ded to '0755'.

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 120;
// Your full path to the images
$loc = str_replace(chr(92),chr(47),getcwd()) . '/gfx/';
$thumb -> Chmodlevel = '0755';
$thumb -> Thumblocation = 'thumbs/';
$thumb -> Thumbsaveas = 'jpg';
$thumb -> Thumbprefix = '120px_thumb_';
if ($dir=@opendir($loc)) {
  while ($filename=@readdir($dir)) {
    if (($filename!='.') && ($filename!='..') && !is_dir($filename)) {
      $extension=strtolower(substr($filename,strrpos($filename,'.')+1,strlen($filename)));
      if ($extension=='jpg' || $extension=='jpeg' || $extension=='png' || $extension=='gif') {
        // Output to file
        // You can add some custom changes for individual images here
        $thumb -> Createthumb($loc . $filename,'file');
      }
    }
  }
}
?>


Now let's add some more options:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 50;
$thumb -> Percentage = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




The standard resizing option is based in pixels, enable the percentage as in the example above and the thumbnail will be resized to 50%. The Thumbsize parameter resizes automatically based on width for landscape images and height for portrait images. In the example below we rotate the image by 90 degrees to obtain a portrait image, which is resized by 50%.

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 50;
$thumb -> Rotate = 90;
$thumb -> Percentage = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




The example below adds a shadow to the thumbnail, the background color is matched with the page background color.

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Shadow = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




Round the corners for a nice effect. The Clip corners function is an array with 7 values;

[0]: 0=disable 1=straight 2=rounded
[1]: Percentage of clipping
[2]: Clip randomly - Boolean 0=disable 1=enable
[3]: Clip top left - Boolean 0=disable 1=enable
[4]: Clip bottom left - Boolean 0=disable 1=enable
[5]: Clip top right - Boolean 0=disable 1=enable
[6]: Clip bottom right - Boolean 0=disable 1=enable

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Clipcorner = array(2,15,0,0,1,1,0);
$thumb -> Createthumb('gfx/image.jpg');
?>




You can also round the corners and make them transparent:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Backgroundcolor = '#0000FF';
$thumb -> Clipcorner = array(2,15,0,1,1,1,1);
$thumb -> Maketransparent = array(1,1,'#0000FF',30);
$thumb -> Createthumb('gfx/image.jpg');
?>




You can add a frame to create a more realistic photo effect:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#FFFFFF';
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Shadow = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




The next example will show a more 'classic' thumbnail using a shadow and frame around the photo and the binder functionality.

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#FFFFFF';
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Shadow = true;
$thumb -> Binder = true;
$thumb -> Binderspacing = 8;
$thumb -> Clipcorner = array(2,15,0,1,1,1,0);
$thumb -> Createthumb('gfx/image.jpg');
?>




Of course it is also possible to watermark your images. The position is determined by providing the XY position in a % of width and height. The position '0% 0%' would be top-left, '100% 100%' will be bottom right. The transparency of the PNG image can be set between 0 and 100. You get the best effect with transparent PNG images as shown in the example below:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#00000';
$thumb -> Backgroundcolor = '#000000';
$thumb -> Clipcorner = array(2,15,0,1,1,1,1);
$thumb -> Watermarkpng = 'watermark.png';
$thumb -> Watermarkposition = '50% 50%';
$thumb -> Watermarktransparency = 70;
$thumb -> Createthumb('gfx/image.jpg');
?>




Another option to protect your copyright is to write a short text on the image. The following example uses the systemfont.
The textcolor, black or white, is automatically determined based on the color of the background of the image.

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Copyrighttext = 'MYWEBMYMAIL.COM';
$thumb -> Copyrightposition = '0% 95%';
$thumb -> Createthumb('gfx/image.jpg');
?>




For a nicer effect you can use a TTF font:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Copyrighttext = 'MYWEBMYMAIL.COM';
$thumb -> Copyrightposition = '50% 90%';
$thumb -> Copyrightfonttype = 'handwriting.ttf';
$thumb -> Copyrightfontsize = 30;
$thumb -> Copyrighttextcolor = '#FFFFFF';
$thumb -> Createthumb('gfx/image.jpg');
?>




Adding a border to the image creates very interesting effects.
In the following example a transparent PNG image with blue border and white inner-frame was used.

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#00000';
$thumb -> Borderpng = 'border.png';
$thumb -> Copyrighttext = 'MYWEBMYMAIL.COM';
$thumb -> Copyrightposition = '50% 80%';
$thumb -> Copyrightfonttype = 'handwriting.ttf';
$thumb -> Copyrightfontsize = 30;
$thumb -> Copyrighttextcolor = '#FFFFFF';
$thumb -> Createthumb('gfx/image.jpg');
?>




Another border example:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Borderpng = 'cloud.png';
$thumb -> Createthumb('gfx/image.jpg');
?>




You can crop the image from the sides or from the center.

The crop function is an array with 6 values;

[0]: 0=disable 1=enable free crop 2=enable center crop
[1]: 0=percentage 1=pixels
[2]: Crop left
[3]: Crop right
[4]: Crop top
[5]: Crop bottom

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Cropimage = array(2,0,20,20,35,35);
$thumb -> Createthumb('gfx/image.jpg');
?>




You can convert the image to greyscal or age it using the aging function which is an array with 3 values;

[0]: Boolean 0=disable 1=enable
[1]: Add noise 0-100, 0=disable
[2]: Sephia depth 0-100, 0=disable (=greyscale)

By adding 'noise' to the image it will look less sharp, the sephia turns it into old darkbrownish colors.

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Shadow = true;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Cropimage = array(2,0,20,20,35,35);
$thumb -> Ageimage = array(1,10,80);
$thumb -> Createthumb('gfx/image.jpg');
?>




You can rotate or flip the image. The following example flips the image over the horizontal axis:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Fliphorizontal = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




Flipping over the vertical axis:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Flipvertical = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




Rotate at any angle without cropping the image, the example below rotates the image over -75 degrees:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Rotate = -75;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Createthumb('gfx/image.jpg');
?>




The 'Square' function will create a square canvas (same width and height - for demonstration the background/canvas is red):

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Backgroundcolor = '#FF0000';
$thumb -> Cropimage = array(2,0,20,20,35,35);
$thumb -> Ageimage = array(1,0,0);
$thumb -> Rotate = 180;
$thumb -> Square = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




You can combine all the above image manipulations, the class will determine the correct order in which to apply them.
Setting the 'Quality' will improve the output result of JPG images:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Backgroundcolor = '#0000FF';
$thumb -> Clipcorner = array(2,15,0,1,1,1,1);
$thumb -> Quality = 100;
$thumb -> Rotate = -35;
$thumb -> Square = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




You can also apply image manipulations without resizing the original image by setting the 'Thumbsize' parameter to zero, as shown below:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 0;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Clipcorner = array(2,5,0,1,1,1,1);
$thumb -> Watermarkpng = 'watermark.png';
$thumb -> Watermarkposition = '0% 100%';
$thumb -> Watermarktransparency = 50;
$thumb -> Copyrighttext = 'Copyright (c)';
$thumb -> Copyrightposition = '100% 90%';
$thumb -> Copyrightfonttype = 'handwriting.ttf';
$thumb -> Copyrightfontsize = 30;
$thumb -> Copyrighttextcolor = '#D0DEEE';
$thumb -> Createthumb('gfx/image.jpg');
?>




New functionality added in version 1.0.2:

User defined filters for PHP4 and PHP5 similar to Paint Shop Pro. A 3x3 filter matrix is applied to the image. The class includes standard filters for sharpening, blurring, embossing and edge detection:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Edge = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Emboss = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Sharpen = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Blur = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




It is also possible to define your own filter and set the divisor and offset parameters:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Filter = array(-1,-1,-1,-1,8,-1,-1,-1,-1);
$thumb -> Divisor = 1;
$thumb -> Offset = 0;
$thumb -> Applyfilter = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




Another function added in version 1.0.2 is the standard rotate() function that rotates and crops the image to fit the canvas:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Rotate = -30;
$thumb -> Croprotate = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




New functionality added in version 2.0.0:

Perspective allows you to create a 2D perspective from the left, right, top or bottom side to the image or thumbnail:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Perspective = array(1,0,20);
$thumb -> Createthumb('gfx/image.jpg');
?>




By using the shading function a shadow gradient can be applied from the left, right, top or bottom side to the image:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Shading = array(1,70,80,0);
$thumb -> Shadingcolor = '#D0DEEE';
$thumb -> Createthumb('gfx/image.jpg');
?>




The mirror effect mirrors a part of the image and uses a gradient for enhanced effect. It is possible to set a reflection gap between the image and reflection:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Mirror = array(1,10,70,40,2);
$thumb -> Mirrorcolor = '#D0DEEE';
$thumb -> Createthumb('gfx/image.jpg');
?>




The negative and grayscale function create true color results:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Greyscale = true;
//$thumb -> Negative = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




Replace colors with the colorreplace function and define a tolerance/sensitivity:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Colorreplace = array(1,'#FFFFFF','#FF6600',60);
$thumb -> Createthumb('gfx/image.jpg');
?>




Define a transparent color with tolerance/sensitivity (8-bit GIF or PNG):

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Maketransparent = array(1,0,'#171915',30);
$thumb -> Createthumb('gfx/image.jpg');
?>




Repositioning pixels randomly creates interesting effects:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Pixelscramble = array(1,4,2);
$thumb -> Createthumb('gfx/image.jpg');
?>




Brightness, contrast and gamma can also be modified:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Brightness = array(1,50);
//$thumb -> Contrast = array(1,30);
//$thumb -> Gamma = array(1,0.5);
$thumb -> Createthumb('gfx/image.jpg');
?>




It is possible to merge/blend a color or reduce the colors in the palette:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Colorize = array(1,0,0,125,0);
//$thumb -> Palette = array(1,64);
$thumb -> Createthumb('gfx/image.jpg');
?>




Noise in images can be reduced by a mean filter, this generally blurs the image:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Mean = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




Another method to reduce noise is with a median filter, which provides excellent results in filtering 'dead' pixels:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Medianfilter = true;
$thumb -> Createthumb('gfx/image.jpg');
?>




Below follow some interesting image deformation filters starting with a simple pixelate filter and ending with mathematical bilineair deformations:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Pixelate = array(1,10);
$thumb -> Createthumb('gfx/image.jpg');
?>




<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Ripplefx = array(1,5,15,5,5);
$thumb -> Createthumb('gfx/image.jpg');
?>




<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Twirlfx = array(1,20,0);
$thumb -> Createthumb('gfx/image.jpg');
?>




<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Lakefx = array(1,15,80);
$thumb -> Createthumb('gfx/image.jpg');
?>




<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Waterdropfx = array(1,1.2,400,40);
$thumb -> Createthumb('gfx/image.jpg');
?>




New functionality added in version 2.0.1:

The function Cropimage() now includes a square scrop, see example below:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 200;
$thumb -> Cropimage = array(3,0,0,0,0,0);
$thumb -> Createthumb('gfx/image.jpg');
?>




New functionality added in version 2.0.3:

The function Create_apng() creates an animated PNG image, see example below (PNG animation is only supported by Mozilla Firefox 3, Opera 9.5, KSquirrel 0.7.2 and XnView 1.92 for the moment, other browsers will display the 1st frame only):

<?php
// First we create some new PNG thumbnails
// Then we create the animation
set_time_limit(0);
$frames = array();
$thumb -> Thumbsaveas = 'png';
$thumb -> Thumbprefix = '';
$thumb -> Thumblocation = '';
$thumb -> Copyrighttext = 'MYWEBMYMAIL.COM';
$thumb -> Copyrightfonttype = 'gfx/handwriting.ttf';
$thumb -> Copyrighttextcolor = '#FFFFFF';
for ($i = 1; $i <= 8; $i++) {
 $frames[] = "frame$i.png";
 $thumb -> Thumbfilename = "frame$i.png";
 $thumb -> Copyrightposition = '50% 50%';
 $thumb -> Copyrightfontsize = $i*4;
 // You can also add the waterdrop effect, but it might time out!
 // $thumb -> Waterdropfx = array(1,$i/6,400,40);
 $thumb -> Createthumb('gfx/image.jpg','file');
}
// Create the animation
$thumb -> Create_apng($frames, 'animation.png', 250);
?>




New functionality added in version 2.0.4:

The Polaroid and displacement map feature, previously only available in the Pro version are now included in the free version:

<?php
include_once('easyphpthumbnailpro.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Shadow = true;
$thumb -> Polaroid = true;
$thumb -> Polaroidtext = 'MYWEBMYMAIL.COM';
$thumb -> Polaroidfonttype = 'handwriting.ttf';
$thumb -> Polaroidfontsize = '30';
$thumb -> Polaroidtextcolor = '#000000';
$thumb -> Createthumb('gfx/image.jpg');
?>




Image deformation is also possible by using a displacement map and bilinear filter. The Red and Green colors of the image in the displacement map are a measure for the X and Y pixel shift in the original image, grey is neutral. You can spend hours discovering effects of displacement maps:

<?php
include_once('easyphpthumbnailpro.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Displacementmap = array(1,'gfx/displacementmap.jpg',0,0,0,50,50);
$thumb -> Createthumb('gfx/image.jpg');
?>










A displacement map can be applied to the image and a 2nd map to the thumbnail creating stunning effects:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Copyrighttext = 'MYWEBMYMAIL.COM';
$thumb -> Copyrightposition = '50% 80%';
$thumb -> Copyrightfonttype = 'gfx/handwriting.ttf';
$thumb -> Copyrightfontsize = 20;
$thumb -> Copyrighttextcolor = '#FFFFFF';
$thumb -> Borderpng = 'gfx/border.png';
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Mirror = array(1,30,90,40,2);
$thumb -> Mirrorcolor = '#D0DEEE';
$thumb -> Displacementmap = array(1,'gfx/displacementmap_ball.jpg',0,0,0,50,50);
$thumb -> Displacementmapthumb = array(1,'gfx/displacementmap.jpg',0,0,200,25,25);
$thumb -> Createthumb('gfx/image.jpg');
?>




By using the Canvas option it is possible to create an image without loading it from file and apply some effects like a text wobble:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Createcanvas(300,50,IMAGETYPE_PNG,'#D0DEEE',false);
$thumb -> Addtext = array(1,'MYWEBMYMAIL.COM','50% 50%','gfx/handwriting.ttf',20,'#FF0000');
$thumb -> Ripplefx = array(1,3,12,0,0);
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#FF6600';
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Shadow = true;
$thumb -> Createthumb();
?>




In order to load pages faster you can embed images in HTML or email messages, called base64 encoded image data:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
echo '<img src="' . $thumb -> Createbase64('gfx/image.jpg') . '" />';
?>




By using the option 'Keeptransparency' you can resize images with transparency:

<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 100;
$thumb -> Keeptransparency = true;
$thumb -> Createthumb('gfx/cloud.png');
?>




Changes in version 2.0.5:

  • Fixed a transparency bug in the function createemptythumbnail(); thanks to Alexander Vasilyev from http://www.Hamster3d.com
  • Added an example for a dynamically created thumbnail


Changes in version 2.0.6:

  • Added EXIF functions to delete, read, and write/overwrite EXIF information in JPG images
  • Fixed bug in imagejpeg function, 2nd parameter should be NULL instead of ''; thanks to Mantas from Lithuania
  • Set chmod level to '0755' for saved images as standard


With any image manipulation you do in PHP, you will loose the EXIF information. The solution below will extract the EXIF information before any changes to the image are made and insert it back in the manipulated image:
