Re: [PHP] How to add a new color to JPEG
Jennifer wrote: it seems to ignore the color that I specify and always came out grey. (Of course now if I use ImageColorClosest(), some colors work because they are in my image.) Any idea on how solutions? Oops. I didn't read far enough. I found the following in a separate thread. I experienced the same, but i use following workaround: Create a new Jpeg, Allocate your colours, and copy your original jpg into the new one. then you have all the colours you have allocated in your new pic... So now my question is, how do I copy one image into another? I see ImageCopy(), but it mentions copying a part of the image, so do I have to use GetImageSize to determine the size of the src image first?

RE: [PHP] How to add a new color to JPEG
I don't know a way around the problem you're describing with your version of PHP, but PHP 4.0.6 with GD 2.0.1 allows you to call ImageCreateTrueColor(), which eliminates the 256-color limitation with JPEG files-- solved my problem right away. -Original Message- From: Jennifer [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 17, 2001 5:55 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] How to add a new color to JPEG -Original Message- From: SED [mailto:[EMAIL PROTECTED]] According to the manual, you can only get closest value of your desired color by letting the ImageColorClosest() find it.

Re: [PHP] How to add a new color to JPEG
has this problem check the annoted manual on php.net. i believe there is a work arround posted on imagecolorallocate() and i reposted the same thing under imagecreatefromjpeg. basically you create and image, allocate colors, and then copy your jpeg on it.

RE: [PHP] How to add a new color to JPEG
That's something you would need to do in photoshop. open your image, select save for web, look to the left of the image, you should see some buttons and a black box. you need to click on the black box, select the yellow you want, and then click ok. Then, click the button above the yellow - that will select the eyedropper. Then, go to the color palette opposite. click on the 3rd icon underneath it, which allows you to add eyedropper color to the palette. That should work. mail me if you get stuck, with your image dimensions/copy of image.

RE: [PHP] How to add a new color to JPEG
I'm not sure I follow. I know this is how I would do it if I had a GIF-image, but this does not include JPEG. Thats the main issue. The JPEG is saved as an RGB-image, not index colored like GIF, therefore I'm asking about how to add a RGB color to a non-index-color-image (JPEG). Are you sure you are talking about JPEG, not GIF?

RE: [PHP] How to add a new color to JPEG
I believe the problem is GD previous to version 2.0.1... They could only create images with indexed (256?) colors... I had a PHP script that used GD to resize JPEGs to smaller thumbnails automatically... And it would always reduce them to 256 colors, until I upgraded to PHP 4.0.6, GD 2.0.1, and used ImageCreateTrueColor() --Matt -Original Message- From: SED [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 10, 2001 9:17 PM To: 'James Cox'; [EMAIL PROTECTED] Subject: RE: [PHP] How to add a new color to JPEG I'm not sure I follow.
