Returning pixel color of an image

Rahmon

Hi guys,

am having troubles determining the true RGB color returned for an image.

imagecolorat() returns RGB color of a pixel. I want to return RGB color for a region (combination of pixels) for an image.

Would appreciate your quick responses.

Regards.

What exactly do you mean "the RGB of a region of pixels"? Different pixels often have different colours and hence different RGB values. Which ones do you want?

Thanks for your reply.

I actually want to determine the color of some part of a picture. This part of the picture should cover some range of pixels.

Suppose the width and height of the picture is 200pixels and 300pixels respectively, is it possible to get the color of the area on the picture covered by width=200 to height=40 for instance.

Again, thanks.

Regards.

Eh?

Are you grabbing colors from a photo or from something like a gif graphic (not many colors)?

Doesn't it seem evident that...

1) you need to pick just one pixel to get a color from.

2) you are going to get back multiple color values from the "range".

3) you need to multiply all the colors values in a range which will very likely result in black.

Honestly, what I believe you are trying to do (but I'm just guessing here) is return an average hex (color) value based upon all the colors in a given range.
