Stretch Rect (WoW64)

This automated test verifies correct implementation of the driver functionality that underlies the IDirect3DDevice9::StretchRect method.

The Stretch Rect test uses the IDirect3D9::CheckDeviceFormat method to determine the combinations of formats and surface types that the driver supports. It also uses the IDirect3D9::CheckDeviceFormatConversion method to determine the color-conversion operations that the driver supports.

For all valid surface-type combinations, the test performs a comprehensive set of StretchRect operations. These operations include those that involve stretching, color conversion, and copies to or from a subset rectangle (subrect). In these test cases, the source surface may be a texture surface (RT or non-RT), an off-screen render target, or an off-screen plain surface. The destination must be a render target or an RT texture surface.

Under D3D9L, the test also considers a more comprehensive set of source and destination surface-type combinations: Each surface may be a non-RT texture surface, an RT texture surface, an off-screen RT, or an off-screen plain surface. All sixteen combinations are tested. However, in compliance with D3D9L specifications, the StretchRect operations are limited to those that involve only full-surface copies without stretching or color conversion.

The test accomplishes automatic verification by rendering both the destination surface and a reference surface and comparing the rendered images. The test uses the LoadSurfaceFromSurface function in D3DX9 to prepare reference images.
