A simple to use and flexible image manipulation symfony plugin. The plugin allows you to perform “transforms” on an image. A transform maybe simple like a resizing or mirroring or more complex like overlays and pixelizing. The transforms can be chained together or applied individually. New transforms can be simple created by extending the sfImageTranform abstract class.

Examples

Starting with the original image:-

Here is an example of a transform that:-

• scales ‘logo.png’ by 50%

public function executeDemo1()
{
 $img = new sfImage(sfConfig::get('sf_upload_dir') . DIRECTORY_SEPARATOR . 'logo.png', 'image/png');
 $response = $this->getResponse();
 $response->setContentType($img->getMIMEType());

 $img->scale(0.5);

 $response->setContent($img);

 return sfView::NONE;
}

Result:-

Here is an example of a transform that:-

• flood fill’s ‘logo.png’ at ‘x100,y170′ with #000000
• scales by 50%
• rotate by 120%
• draw a rectancle of 5 pixels around edge and colour it #00FF00
• write the text “bathcamp 2008″ at ‘x10,y10′ 10px Verdana coloured #FF9900

public function executeDemo5()
{
 $img = new sfImage(sfConfig::get('sf_upload_dir') . DIRECTORY_SEPARATOR . 'logo.png', 'image/png');
 $response = $this->getResponse();
 $response->setContentType($img->getMIMEType());

 $img->fill(100,170)->scale(0.5)->rotate(120)->rectangle(1, 1, $img->getWidth() - 1, $img->getHeight() - 5, 5, '#00FF00')->text('bathcamp 2008', 10, 10, 10, 'Verdana', '#FF9900');

 $response->setContent($img);

 return sfView::NONE;
}

Result

Stunami has provided a collection of transforms for the GD and ImageMagick libraries.

I took the idea of “transform” and thought of a new butterfly emerging from it’s chrysalis, seeing as my mum is the Publicity Officer of the Hampshire and Isle of Wight Butterfly Conservation the idea sprung to mind. Having seen the bathCamp logo on the bathCamp Blog

bathCamp Logo

I thought it fitting to use some of the logo’s elements and colours, it fitted perfectly so now let’s hope that Stu likes it!

Both Stu and I are going to bathCamp this weekend to enjoy the company of the cool geeks in the south-west. It’s our first time doing this kid of thing, so it’s with open eyes and an open mind that we take with us to this event. We’re both looking forward to it and hope that our talk is going to be of use to some.
