Help about GD

[mamylo]

Hey my friends
I have a GIF image with 2 colors, white and transparent.
For example it's a white circle in center of image, with transparency around that circle.
Now I want to make a border around that circle with php GD library (sth like Stroke in Photoshop), can I do that? How?

Thanks in advance and sorry about my bad English

It might be possible to import your original graphic file and then draw the border around your circle using the imageelipse() function. I have not done much work with transparency in GD, so I cannot give you any example code.

It might be easier to create a new image file using ImageMagick if it is installed on your server. ImageMagick has direct support for fill and stroke colors and makes it easy to create an image with a transparent background.

Dear rainborick, I cannot use imageelipse because the content of the image is not exactly a circle :(

That's too bad. I think you will have to use a program like Photoshop to draw your border. It might be possible to do it with a PHP script, but I think it would be more difficult to write the script than it would be to use a program like Photoshop. Good luck!
