hi list,

I have to load a huge image of about 23000 pixels x 700 pixels in order to be as a landscape image scrolling in slow motion with a certain time sequencer.

That's too big for most graphics cards. Not sure if there is a way in Gem to query the maximum texture dimensions, but in C you'd use proxy targets for glTexImage2D. Typically textures go up to 8192 or another nearby power of two in each dimension.

I m testing with pix_image and pix_multiimage but seems to load only a fragment of the image about 1000pixels (horizontal) cropping and not rendering the rest.

Split it into vertical slices and display them on a lot of quads. You might have to be tricky with pixel positioning to avoid seams. I did this once in gridflow, don't know where the patch is though (6 years ago at least) - so maybe you could try the gridflow/Gem bridge if it hasn't bitrotted too hard.

(the size of the image is about 1.2M in jpg)

That's irrelevant, it's decompressed before you put it in video memory.

Any suggestion? thanx Xavi M.dAAX
