The Little Guy Posted March 19, 2011 Share Posted March 19, 2011 I am making an image CAPTCHA, and I want to blur some letters but not others. I have this: shell_exec($opt = "mogrify -blur $blur -font $font -fill '$color' -pointsize $size -draw \"text $txS,$tyP '".$text{$i}."'\" $file"); It is in a loop, and it runs for every letter, setting all the properties, but the first letter is blurred the most and the last letter is blurred the least or not at all. Is there any way I can set a blur for each letter instead of blurring whole image?

JonnoTheDev Posted March 21, 2011 Share Posted March 21, 2011 Probably is but without scouring the manual the method I suggest would be to create x number of images & layer them into 1. Lets say your captcha contains 5 characters. I would create 5 images of lets say 20 x 20 using a different blur level for each. Take the 5 images and layer them onto a new canvas of 100 x 20.

The Little Guy Posted March 23, 2011 Author Share Posted March 23, 2011 What I did, was place this in a loop: shell_exec($opt = "convert -size {$canvas_width}x{$this->height} xc:'$this->bgColor' -font $font -fill '$color' -pointsize $size -draw \"gravity center text 0,0'".$text{$i}."'\" -blur 0x$blur $file +append $file"); Link to comment https://forums.phpfreaks.com/topic/231062-imagemagick-blur/#findComment-1191179 Share on other sites More sharing options...
