class HPS::DrawWindowEvent : public HPS::DriverEvent
The DrawWindowEvent class is the event generated when the driver draws the window background for each subwindow.
Public Types
-
enum BackgroundTextureFormat
Enumerates the various texture formats supported by the DrawTexturedBackground function .
Values:
-
enumerator RGBA
Handle to single GL_RGBA format texture.
-
enumerator BGRA
Same as RGBA but with swapped red and blue channels.
-
enumerator ImageExternal
Handle to single OES_EGL_image_external texture.
-
enumerator LumaChromaPair
Pointer to array of two texture handles for a YCbCr texture pair (For OpenGL ES, the formats should be GL_LUMINANCE and GL_LUMINANCE_ALPHA. For Metal, the formats should be MTLPixelFormatR8Unorm and MTLPixelFormatRG8Unorm).

- Parameters
in_texture – The platform-specific texture handle(s)
in_format – The format of the texture(s) provided through the ‘in_texture’ parameter.
