I have a problem.
First I make surface with prelocated data(default videomode 640x480x16):
size = 64*64*2;
void *bmpdata = malloc(size);
bmpdata = memset (&bmpdata,0xFF,size); //white square 64x64
Then I Create surface and blit:
out_desc.caps = DSCAPS_SYSTEMONLY;
out_desc.flags=(DFBSurfaceDescriptionFlags)(DSDESC_CAPS|DSDESC_WIDTH|DSDESC_HEIGHT|DSDESC_PIXELFORMAT|DSDESC_PREALLOCATED);
out_desc.width = 64;
out_desc.height = 64;
out_desc.pixelformat = DSPF_RGB16;
out_desc.preallocated[0].data = (void*) bmpdata;
out_desc.preallocated[0].pitch = 64*2;
out_desc.preallocated[1].data = NULL; //What is it? Please answer.
out_desc.preallocated[1].pitch = 0;
DFBCHECK( dfb->CreateSurface( dfb, &out_desc, &out_surface ) )
DFBCHECK (primary->Blit(primary,out_surface,NULL,200,200));
DFBCHECK (primary->Flip (primary, NULL, 0));
And I see white square but top side of them is not line (set of random
points). Where is a error? (full source attached)
Also How can I bli surface with pixelformat DSPF_A1 to primary surface
with RGB16?
Please, answer.
