------- Additional Comments From tony_lambregts@telusplanet.net 2002-07-01 10:29 ------- This is what MSDN has to say about DDBLT_DDFX
DDBLT_DDFX Uses the *dwDDFX* member of the *DDBLTFX* http://msdn.microsoft.com/archive/en-us/ddraw7/directdraw7/ddref_0xmf.asp structure to specify the effects to use for this blit.
and these are the possible effects that need to be covered. of course we can only fix what we can test so it probably is only a subset of this .
*dwDDFX* Type of FX operations. The following types are defined:
DDBLTFX_ARITHSTRETCHY Uses arithmetic stretching
http://msdn.microsoft.com/archive/en-us/ddraw7/directdraw7/glossary_459v.asp#_dx_stretching_glos along the y-axis for this blit. DDBLTFX_MIRRORLEFTRIGHT Turns the surface on its y-axis. This blit mirrors the surface from left to right. DDBLTFX_MIRRORUPDOWN Turns the surface on its x-axis. This blit mirrors the surface from top to bottom. DDBLTFX_NOTEARING Schedules this blit to avoid tearing
http://msdn.microsoft.com/archive/en-us/ddraw7/directdraw7/glossary_85rn.asp#_dx_tearing_glos. DDBLTFX_ROTATE180 Rotates the surface 180 degrees clockwise during this blit. DDBLTFX_ROTATE270 Rotates the surface 270 degrees clockwise during this blit. DDBLTFX_ROTATE90 Rotates the surface 90 degrees clockwise during this blit. DDBLTFX_ZBUFFERBASEDEST Adds the *dwZBufferBaseDest* member to each of the source z-values before comparing them with the destination z-values during this z-blit. DDBLTFX_ZBUFFERRANGE Uses the *dwZBufferLow* and *dwZBufferHigh* members as range values to specify limits to the bits copied from a source surface during this z-blit.
