Hallo,
I have a problem with bmap_process.
I get, that I can only use bitmaps sizes that are a power of two.
But if I process a bitmap with 2048 (my calculator says it is 2^11 ergo a power of two) the texture coordinates are messed up.
I wrote this testshader:
float4 process_test(in float2 tex: TEXCOORD0): COLOR
{
return float4(tex.x, tex.y, tex.x, tex.y);
}
And wrote the result per bmap_process into a 32bit floating point bitmap.
BMAP *test = bmap_createblack(2048, 2048, 14);
bmap_process(test, test, mtlProjectText);
bmap_to_format(test, 14);
bmap_lock(test, 0);
float *bits = test.finalbits;
str_for_float(deb1, bits[2047]);
bmap_unlock(test);
result is 0.8...
if the bitmap is 1024 result is 0.99....
So why?
