RE: [PHP] Image color quality problems
Not an answer I'm afraid but does PHP has the ability to do this with JPEGs? Would be VERY useful to me if it does! - seb -Original Message- From: Kurt Lieber [mailto:[EMAIL PROTECTED]] Sent: 21 July 2001 23:27 To: [EMAIL PROTECTED] Subject: [PHP] Image color quality problems I have the following code that takes an existing image, creates a new one from it and writes some white text on top of that image: ?php header(Content-type: image/png); $startingImage = leftphoto_01.png; $image = imageCreateFromPNG($startingImage); //$white = imageColorAt($image, 30, 215); $white = imageColorAllocate($image, 255, 255, 255); imageTTFText($image, 24, 0, 10, 25, $white, arialbd.ttf, This is a test); imagePNG($image); imagedestroy($image); ? Problem is, the white text isn't white -- it's a dingy gray color. From reading around, I thought maybe if I took an existing white pixel in the image and used that to set white, that might help (hence the commented out //$white = imageColorAt... line in my code above) That didn't help either. (and the pixel I sampled is exactly the shade of white I want) I am almost completely unfamiliar with color pallettes and how to manipulate them. Can someone shed some light on how I can get some clean, bright white text on my image?

RE: [PHP] Image color quality problems
Yes, it does, through the use of the GD and freetype libraries.

RE: [PHP] Image color quality problems
Thanks Kurt. Unfortunately my server only has gd 1.6.2 (gd 1.8.3 required aparantly) and I can't change that.

RE: [PHP] Image color quality problems
Check out the PHP dl() function: http://www.php.net/dl It lets you load an extension at run-time, so if you can compile the newer version of GD, you may be able to download that directly. Only thing I'm not sure about is if you can override an already-loaded extension by downloading a newer version of the same extension. Maybe if you simply named it something different -- gd-1.8.3.so, for example. Can anyone confirm whether this would work or not? -Original Message- From: Seb Frost [mailto:[EMAIL PROTECTED]] Sent: Saturday, July 21, 2001 4:30 PM To: Kurt Lieber; [EMAIL PROTECTED] Subject: RE: [PHP] Image color quality problems Thanks Kurt.
