After bmap_process missing text in the dest bitmap

After bmap_process missing text in the dest bitmap - 09/11/20 19:50

If I use bmap_process(BMAP* bmDest, BMAP* bmSrc, MATERIAL* mtl); after copying text into a bmSrc, I miss the text in the bmDest.

A. First I copy a small bitmap into a big buffer bitmap...

Code

bmap_blit(bmapBuffer_800x600, bmapPhoto_40x40, vector(10,10,0), vector(0,0,0));  //I copy a photo into the buffer bitmap

B. 2nd I copy a text into the same big buffer bitmap...

Code

textHalloWorld.target_map = bmapBuffer_800x600; //I copy a text into the same buffer bitmap

As far the big buffer bitmap 'bmapBuffer_800x600' contains small bitmap 'bmapPhoto_40x40' as well as the text 'textHalloWorld'[i].

C.After using a shader on [i]'bmapBuffer_800x600' and store the result in another bit bitmap 'bmapShader', the text is missing in the new 'bmapShader'.

Code

bmap_process(bmapShader, bmapBuffer_800x600, mtl_sepia); //text missing!

proc_mode = PROC_EARLY; at the beginning of the function resolves the problem.

Code

proc_mode = PROC_EARLY
bmap_blit(bmapBuffer_800x600, bmapPhoto_40x40, vector(10,10,0), vector(0,0,0));  //I copy a photo into the buffer bitmap
textHalloWorld.target_map = bmapBuffer_800x600; //I copy a text into the same buffer bitmap
bmap_process(bmapShader, bmapBuffer_800x600, mtl_sepia); //use sepia shader onto bmapBuffer_800x600 and store result in bmapShader

I was wrong - seems you have to wait 1 tick after you put in a text into a bitmap before you use bmap_process();.

Code

bmap_blit(bmapBuffer_800x600, bmapPhoto_40x40, vector(10,10,0), vector(0,0,0));  //I copy a photo into the buffer bitmap
textHalloWorld.target_map = bmapBuffer_800x600; //I copy a text into the same buffer bitmap

wait(1);

bmap_process(bmapShader, bmapBuffer_800x600, mtl_sepia); //use sepia shader onto bmapBuffer_800x600 and store result in bmapShader

I think the tick is needed for blitting the text into the bitmap.
