Does Bitmap::cache() handle compressed images automatically?

ALAMI_Othmane

Hey,

I have my images stored compressed (ARGB8888) on NAND flash accessed via FileX. Not memory mapped, so I need to cache everything before starting the GUI.

I noticed this in the Bitmap API docs:

Bitmap::decompress — "This method is called by Bitmap::cache when required."

So does that mean I just implement BlockCopy with FileX, call Bitmap::cache(), and it handles the decompression automatically? Does it allocate for the uncompressed size and deal with the temp buffers internally?

Would save me a lot of headache if that's the case;

Thanks!

Is this a TouchGFX question?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
Yes, forget to mention it

OK - moved it to the TouchGFX forum & added the label.
