ref_iface_IVDXAContext_GetTextureDesc
VirtualDub Plugin SDK 1.2
IVDXAContext interface
Retrieves allocation parameters of a texture.
void GetTextureDesc(uint32 handle, VDXATextureDesc& desc);
handle | Handle to texture to query; must be valid (non-zero). This may either be a plain texture or a renderable texture. |
desc | Structure object to receive a description of the texture. |
This method is not thread-safe.
This method is primarily useful in computing custom UV mappings with source frame textures, since the UVs used for sampling must match the physical texture and not the logical parameters used to allocate it.
