Trying to get pixel color data for every pixel in an image
Posted: 2010-12-19T11:39:03-07:00
The images will be smaller like 300x60 or so on average... but the method I am using is way too slow... is there a faster way than the php example below?
Below is an example of how I would like the data to look. Actually just rgb values would be fine too.
Code: Select all
$image = 'test.jpg';
$imageSize = getimagesize($image);
for($w=0; $w<=$imageSize[0]; $w++){
for($h=0; $h<=$imageSize[1]; $h++){
$txt[$w][$h] = exec('convert '.$image.'[1x1+'.$w.'+'.$h.'] txt:');
}
}
debug($txt);
Code: Select all
