Editing an Image using the GD Library and PHP

[The Fiery Ice Alchemist]

Is it possible to take an image, dissect a section off and display just that section?
like taking this image:

and just showing the "Move Left Card"?

Well there's definitely a way, I'm sure of that. As for which feature... I'm not entirely sure. You'd have to throw in the dimensions of a card, and the width of the spacing, and define how many cards tall and wide the image is, and then use a function to copy the image from the coordinates. So the Move Left card would start at X-coord (($cardwidth * 3) + ($spacing * 3)) and Y-coord 0, and then you'd tell it to copy a rectangle from the starting X-coord and Y-coord to (X-coord1 + $cardwidth) and (Y-coord1 + $cardheight).
I could probably look into the code for you sometime tomorrow if you like. I haven't played around with GD too much yet, but I'm good at figuring out new functions pretty quickly.
If worst came to worst, you could always create a second image with the dimensions of a card, and copy them over row by row, pixel by pixel, using some for loops. But I'm certain there's gotta be a much more efficient means.

surely:
imagecopy()

imagecopy($image_dest, $image_src, $dst_x, $dst_y, $src_x, $src_y, $src_w, $src_h)

That will take the region with top left corner $src_x, $src_y, with width $src_w and height $src_h, and paste it on $image_dest with top left corner at $dst_x, $dst_y. If you want this to be the wholenew image, make the $image_dest with

imagecreate($src_w, $src_h)

and then paste at 0,0

Ah, but that copies a rectangular region, right? The cards have rounded corners, so as long as you don't mind showing a little bit of swirly background pattern around the corners, it'll work fine.

That really cant be avoided using this method, GD has a _very_ limited library. If he just made seperate cards and then GDed them together it would be much easier.
