I’m going to be releasing documentation on my development framework, Datalus<\/a>, in the near future… but before that, I’ll be releasing a few examples using the utility libraries from it.<\/p>\n

My first example uses a stacked imaging framework built on top of GD who’s goal is to implement the feature set of photoshop 3. It may only be to about 30% of that goal, but it’s well past useful.<\/p>\n

So let’s take this some images:
\n\"\"<\/a>
\n\"\"<\/a>
\n\"\"<\/a><\/p>\n

Then we’ll write a script to combine these images:<\/p>\n

require('.\/ImageBooth.php');\n\n    $raw_image = imagecreatefromjpeg('.\/captcha.jpg');\n    $overlay_image = imagecreatefrompng('.\/captcha2.png');\n    $checks = imagecreatefrompng('.\/checks.png');\n    $image = ImageBooth::newImage(70, 200);\n    $image->newLayer($raw_image, 'base');\n    $image->newLayer($checks, 'checks');\n    $image->newLayer($overlay_image, 'overlay');\n    $image->filter('blur', array('amount'=>'400'));\n    $image->operate('color_replace', array('origin_color'=>'333388', 'destination_color'=>'CC0000'));\n    $image->operate('brightness_contrast', array('brightness_adjustment'=>-20, 'contrast_adjustment'=>20));\n    $image->operate('negative');\n    $image->selectLayer('checks');\n    $image->transform('rotate', array('angle'=>15));\n    $image->resize(400, 200);\n    $image->resizeCanvas(500, 500);\n    $image->dumpToBrowser();<\/code><\/pre>\n
Now check out the result:

That’s it. Download<\/a> it.<\/p>\n","protected":false},"excerpt":{"rendered":"
