Hi all,
I have doubt in DSBLIT_SRC_COLORKEY. I have two surface called
as primary and secondary surface. While Blitting (copying the
Secondary surface into primary), I need to copy pixel that doesn't match the
source color key.
I have done like the below.
ret = primary->SetBlittingFlags(primary,DSBLIT_SRC_COLORKEY);
ret = primary->SetSrcColorKey(primary,0xFF,0x00,0x00);
primary->Blit(primary,secondary,&rect,50,100);
is any thing wrong with the code?
Problem : If I set the source color key as black the functionality of
DSBLIT_SRC_COLORKEY is working fine,
if I set any other color other than black for source color key , the
functionality of DSBLIT_SRC_COLORKEY is not working.
The full source code is below.
#include <directfb.h>
#include <time.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
static IDirectFB *dfb = NULL;
static IDirectFBSurface *primary = NULL;
static IDirectFBSurface *secondary = NULL;
static DFBRectangle rect;
int
main( int argc, char *argv[] )
{
DFBResult ret;
DFBSurfaceDescription desc;
/* Initialize DirectFB including command line parsing. */
ret = DirectFBInit( &argc, &argv );
if (ret) {
DirectFBError( "DirectFBInit() failed", ret );
}
/* Create the super interface. */
ret = DirectFBCreate( &dfb );
if (ret) {
DirectFBError( "DirectFBCreate() failed", ret );
}
desc.flags = DSDESC_CAPS;
desc.caps = DSCAPS_PRIMARY | DSCAPS_DOUBLE;
/* Create the primary surface. */
ret = dfb->CreateSurface( dfb, &desc, &primary );
if (ret) {
DirectFBError( "IDirectFB::CreateSurface() failed", ret );
}
rect.x = 0;
rect.y = 0;
rect.w = 50;
rect.h = 50;
ret = primary->GetSubSurface(primary,&rect,&secondary);
if (ret) {
DirectFBError( "IDirectFB::CreateSurface() failed", ret );
}
primary->Clear( primary, 0xFF, 0x00, 0xFF, 0xFF );
secondary->SetColor(secondary,0xFF,0x00,0x00,0x00);
secondary->FillRectangle(secondary,0,0,50,50);
secondary->Flip( secondary, NULL, 0 );
rect.x = 0;
rect.y = 0;
rect.w = 50;
rect.h = 50;
ret = primary->SetBlittingFlags(primary,DSBLIT_SRC_COLORKEY);
ret = primary->SetSrcColorKey(primary,0xFF,0x00,0x00);
primary->Blit(primary,secondary,&rect,50,100);
primary->Flip( primary, NULL, 0 );
sleep(100);
/* Release the primary surface. */
if (primary)
primary->Release( primary );
/* Release the super interface. */
if (dfb)
dfb->Release( dfb );
}
Thanks in advance,
Dharma.
