I've developed a well-documented, fairly rock-solid API for creating on the fly, anti-aliased, rounded corner images, including full alpha transparency support for all you PNG lovers.
go here to download the package:
http://sourceforge.net/projects/roundedphp/
go here for a live demo:
http://dev.kingthief.com/demos/roundedphp/
Installation is similar to PEAR.
Enjoy!
LXIV. Image Functions
Úvod
PHP is not limited to creating just HTML output. It can also be used to create and manipulate image files in a variety of different image formats, including gif, png, jpg, wbmp, and xpm. Even more convenient, PHP can output image streams directly to a browser. You will need to compile PHP with the GD library of image functions for this to work. GD and PHP may also require other libraries, depending on which image formats you want to work with.
You can use the image functions in PHP to get the size of JPEG, GIF, PNG, SWF, TIFF and JPEG2000 images.
With the exif extension, you are able to work with information stored in headers of JPEG and TIFF images. This way you can read meta data generated by digital cameras. The exif functions do not require the GD library.
Poznámka: Read the requirements section about how to expand image capabilities to read, write and modify images. To read meta data of pictures taken by digital cameras you need the above mentioned exif extension.
Požadavky
If you have the GD library (available at » http://www.boutell.com/gd/) you will also be able to create and manipulate images.
The format of images you are able to manipulate depend on the version of GD you install, and any other libraries GD might need to access those image formats. Versions of GD older than gd-1.6 support GIF format images, and do not support PNG, where versions greater than gd-1.6 and less than gd-2.0.28 support PNG, not GIF. GIF support was re-enabled in gd-2.0.28.
Poznámka: Since PHP 4.3 there is a bundled version of the GD lib. This bundled version has some additional features like alpha blending, and should be used in preference to the external library since its codebase is better maintained and more stable.
Poznámka: Support for GD 1.x has been removed as of PHP 6.0.0, which requires GD 2.0.33 or later.
You may wish to enhance GD to handle more image formats.
Tabulka 113. Supported image formats
| Image format | Library to download | Notes |
|---|---|---|
| gif | Only supported in GD versions older than gd-1.6 and newer than gd-2.0.28. Read-only GIF support is available with PHP 4.3.0 and the bundled GD-library. Write support is available since PHP 4.3.9 and PHP 5.0.1. | |
| jpeg-6b | » ftp://ftp.uu.net/graphics/jpeg/ | When buliding the jpeg-v6b library (prior to building PHP) you must use the --enable-shared option in the configure step. If you do not, you will receive an error saying libjpeg.(a|so) not found when you get to the configure step of building PHP. |
| png | » http://www.libpng.org/pub/png/libpng.html | Only supported in GD versions greater than gd-1.6. |
| xpm | » ftp://metalab.unc.edu/pub/Linux/libs/X/!INDEX.html | It's likely you have this library already available, if your system has an installed X-Environment. |
You may wish to enhance GD to deal with different fonts. The following font libraries are supported:
Tabulka 114. Supported font libraries
| Font library | Download | Notes |
|---|---|---|
| FreeType 1.x | » http://www.freetype.org/ | Support removed as of PHP 6.0.0 |
| FreeType 2 | » http://www.freetype.org/ | |
| T1lib | » ftp://sunsite.unc.edu/pub/Linux/libs/graphics/) | Support for Postscript Type 1 fonts. |
Instalace
To enable GD-support configure PHP --with-gd[=DIR], where DIR is the GD base install directory. To use the recommended bundled version of the GD library (which was first bundled in PHP 4.3.0), use the configure option --with-gd. GD library requires libpng™ and libjpeg™ to compile.
In Windows, you'll include the GD2 DLL php_gd2.dll as an extension in php.ini. The GD1 DLL php_gd.dll was removed in PHP 4.3.2. Also note that the preferred truecolor image functions, such as imagecreatetruecolor(), require GD2.
To disable GD support in PHP 3 add --without-gd to your configure line.
Enhance the capabilities of GD to handle more image formats by specifying the --with-XXXX configure switch to your PHP configure line.
Tabulka 115. Supported image formats
| Image Format | Configure Switch |
|---|---|
| jpeg-6b | To enable support for jpeg-6b add --with-jpeg-dir=DIR. |
| png | To enable support for png add --with-png-dir=DIR. Note, libpng requires the zlib library, therefore add --with-zlib-dir[=DIR] to your configure line. |
| xpm | To enable support for xpm add --with-xpm-dir=DIR. If configure is not able to find the required libraries, you may add the path to your X11 libraries. |
Poznámka: When compiling PHP with libpng, you must use the same version that was linked with the GD library.
Enhance the capabilities of GD to deal with different fonts by specifying the --with-XXXX configure switch to your PHP configure line.
Tabulka 116. Supported font libraries
| Font library | Configure Switch |
|---|---|
| FreeType 1.x | To enable support for FreeType 1.x add --with-ttf[=DIR]. |
| FreeType 2 | To enable support for FreeType 2 add --with-freetype-dir=DIR. |
| T1lib | To enable support for T1lib (Postscript Type 1 fonts) add --with-t1lib[=DIR]. |
| Native TrueType string function | To enable support for native TrueType string function add --enable-gd-native-ttf. |
Konfigurace běhu
There are no image specific configurations but you may be interested in the exif extension directives.
Varování
Image functions are very memory intensive. Be sure to set memory_limit high enough.
Typy prostředků
This extension defines two resource types: an image identifier and a font identifier.

Příklady
Příklad 767. PNG creation with PHP
<?php
header("Content-type: image/png");
$string = $_GET['text'];
$im = imagecreatefrompng("images/button1.png");
$orange = imagecolorallocate($im, 220, 210, 60);
$px = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im);
imagedestroy($im);
?>
This example would be called from a page with a tag like: <img src="button.php?text=text">. The above button.php script then takes this "text" string and overlays it on top of a base image which in this case is "images/button1.png" and outputs the resulting image. This is a very convenient way to avoid having to draw new button images every time you want to change the text of a button. With this method they are dynamically generated.

If you happen to need a way to output a Windows BMP file (e.g. when using the PEAR ExcelWriter), feel free to use the following code:
<?php
function imagebmp ($im, $fn = false)
{
if (!$im) return false;
if ($fn === false) $fn = 'php://output';
$f = fopen ($fn, "w");
if (!$f) return false;
//Image dimensions
$biWidth = imagesx ($im);
$biHeight = imagesy ($im);
$biBPLine = $biWidth * 3;
$biStride = ($biBPLine + 3) & ~3;
$biSizeImage = $biStride * $biHeight;
$bfOffBits = 54;
$bfSize = $bfOffBits + $biSizeImage;
//BITMAPFILEHEADER
fwrite ($f, 'BM', 2);
fwrite ($f, pack ('VvvV', $bfSize, 0, 0, $bfOffBits));
//BITMAPINFO (BITMAPINFOHEADER)
fwrite ($f, pack ('VVVvvVVVVVV', 40, $biWidth, $biHeight, 1, 24, 0, $biSizeImage, 0, 0, 0, 0));
$numpad = $biStride - $biBPLine;
for ($y = $biHeight - 1; $y >= 0; --$y)
{
for ($x = 0; $x < $biWidth; ++$x)
{
$col = imagecolorat ($im, $x, $y);
fwrite ($f, pack ('V', $col), 3);
}
for ($i = 0; $i < $numpad; ++$i)
fwrite ($f, pack ('C', 0));
}
fclose ($f);
return true;
}
?>
It works the same way as regular imagejpeg/imagepng do and only supports GD2.0 true colour bitmaps (which is what's required by ExcelWriter).

While I was searching for a good way to draw a graph, I stumbled on skumar2k15's script.
I have taken the liberty to improve multiple aspects of it.
1. The array can grow and shrink in size, the graph will adjust accordingly.
2. All the values in the array are recalculated so they won't get bigger than the height of the graph.
3. I inserted the possibility to keep a percentage off the height away from the edge.
4. You can adjust the size of the grid.
5. Everything will adjust when you change the height of width.
<?
header("Content-type: image/png");
// Define variables
$Values=array(50,90,30,155,50,40,320,50,40,86,240,128,650,540,320);
$imgWidth=500;
$imgHeight=200;
$grid=25;
$graphspacing=0.05;
//Creation of new array with hight adjusted values
while (list($key, $val) = each($Values))
{if($val>$max){$max=$val;}}
for ($i=0; $i<count($Values); $i++){
$graphValues[$i] = $Values[$i] * (($imgHeight*(1-$graphspacing))/$max);
}
// Create image and define colors
$image=imagecreate($imgWidth, $imgHeight);
$colorWhite=imagecolorallocate($image, 255, 255, 255);
$colorGrey=imagecolorallocate($image, 192, 192, 192);
$colorBlue=imagecolorallocate($image, 0, 0, 255);

The image sharpen function (by Alex R. Austin) provided below seems to be very resource hungry and I couldn't make it work on two different servers - trying to sharpen a 413 x 413 image I ended up with "Fatal error: Allowed memory size of 8388608 bytes exhausted" or "Internal Server Error" or the script terminated without notice. Because I had no priviliges to change the default memory limit on these servers I started looking for other sharpen functions. I have come across a php Unsharp Mask function which works like a charm on both of the servers I dealt with. It can be found at http://vikjavev.no/hovudsida/umtestside.php.

For fedora core 4 users that find that the gd library isn't installed, you can issue the command (as root)
# yum install php-gd
it should download and install the gd library. You will need to restart apache... phpinfo() should then tell you "GD Support enabled".

To sharpen an image, rather than using the code below that produces a sharpening filter with php, use the built-in GD function "imageconvolution" which is designed for this purpose. Matrices can be used for sharpening, blurring, edge detection, etc, ala Photoshop.
A sharpening example:
<?php
$sharpenMatrix = array(-1,-1,-1,-1,16,-1,-1,-1,-1);
$divisor = 8;
$offset = 0;
imageconvolution($myImage, $sharpenMatrix, $divisor, $offset);
?>
Below is some information on building different kinds of matrices. (If you have photoshop (or PSP, GIMP) you can test out your matrices before applying them in PHP)
