After bmap_process missing text in the dest bitmap #481419 09/11/20 19:50 09/11/20 19:50

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! Don't take the cake to the party.

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

Don't take the cake to the party.

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 Don't take the cake to the party.
