Prototype declaration:
KMSTATUS KMAPI kmChangeContextTextureAddress( IN OUT PKMVERTEXBUFFDESC pVertexBuffDesc, IN KMINT32 nParam, IN PKMSURFACEDESC pTextureSurfaceDesc );
Description:
Parameters:This function changes the rendering parameter TextureAddress that was registered in pGlobalParam from pVertexBuffDesc by kmSetVertexRenderState/kmSetStripHead. Because it does not make any changes other than in TextureAddress, this API can be used when the following members are not being changed. pTextureSurfaceDesc->PixelFormat pTextureSurfaceDesc->u0.USize pTextureSurfaceDesc->u1.VSize pTextureSurfaceDesc->fSurfaceFlags If there are any changes in the above members, use kmChangeContextTextureSurface, not kmChangeContextTextureAddress. The following is a list of supported VertexType:
VertexType00 ![]()
VertexType06 ![]()
VertexType12 ![]()
VertexType01 ![]()
VertexType07 ![]()
VertexType13 ![]()
VertexType02 ![]()
VertexType08 ![]()
VertexType14 ![]()
VertexType03 ![]()
VertexType09 ![]()
VertexType15 ![]()
VertexType04 ![]()
VertexType10 ![]()
VertexType16 ![]()
VertexType05 ![]()
VertexType11 ![]()
VertexType17 ![]()
: KM_IMAGE_PARAM1 / KM_IMAGE_PARAM2 can be used.
: Only KM_IMAGE_PARAM1can be used.
Return values:pVertexBuffDesc(input/output) This parameter is a pointer to KMVERTEXBUFFDESC. nParam(input) This parameter specifies the parameter for update. KM_IMAGE_PARAM1 parameter 1 KM_IMAGE_PARAM2 parameter 2 pTextureSurfaceDesc(input) This parameter is a pointer to KMSURFACEDESC.
