Scrolling textures larger than 1024 x 1024 ?

Is it possible to scroll a texture larger than 1024 pixels? I have one that is 1024 x 5000 but when it scrolls the text is squished down so it looks like it is 1024 x 1024.

SL compresses your textures on upload, and forces them to sizes that are "powers of two". The upper limit is 1024. Within SL, your 1024x5000 texture is actually 1024x1024.

If you need to scroll lengthy text such as a credit roll, the only method that comes to mind is to use a moving prim. Imagine something like a five-faced XyText prim rotated 90°. You could apply five 1024x1024 textures giving you the apparent resolution of 1024x5120. But, you'd need to create a window, so the viewer only sees a portion of the prim as it scrolls.

I don't think you can actually get a dimension larger than 1024 now, can you? Not that I'd want to. The thing would take an AGE to load for most people, so they'd never see it.

stretch your prim to restore the texture's original ratio or play with the size and offsets in the texture edit window of the build tool. texture animation will help with ACTUAL scrolling.

PS and yeah I think the current viewer and maybe the server filters the sizes down to 1024^2 max. with the exception of mega prims, that should look fine, and you can probably get away with much less.

ETA:
the power of 2 resizing happens per dimension, so 512x1024 and other variations are valid
