Using UL_IMAGE with PALIB ?

[cuicui666]

Hello everyone,

I'm starting a new project on my DS using uLibrary AND palib.
In the bottom screen (using uLibrary), I loaded several images (with the type UL_IMAGE).

If I want to draw those images on the top screen, is there a way to reuse the data contained in an UL_IMAGE and display it with PALIB ?

I'm sorry, but there's no "simple" way to do it. If you're an expert, you can always find some tricks to do it, but it's really not straightforward.
In fact a pointer to the actual image data can be obtained with ulLockImage (don't forget to unlock it then). It's a bitmap whose width is image->sysSizeX pixels (pixel size in bits is ul_pixelSizes[image->format]) and height is image->sizeY, and the pixel format depends from image->format.
You could do interesting things with this, like convert it to a tiled bitmap or something, but as you see it's not simple :(

Thank you for the answer, I'll see what I can do :)
