List of all members.

Public Types

DiffuseMap

NormalMap

AlphaMap

LuminanceMap

PreserveSize = BIT(0)

Never shrink this bitmap in low VRAM situations.

NoMipmap = BIT(1)

Do not generate mipmap chain for this texture.

SystemMemory = BIT(2)

System memory texture - isn't uploaded to card - useful as target for copying surface data out of video ram.

RenderTarget = BIT(3)

This texture will be used as a render target.

Dynamic = BIT(4)

This texture may be refreshed. (Precludes Static).

Static = BIT(5)

This texture will never be modified once loaded. (Precludes Dynamic).

NoPadding = BIT(6)

Do not pad this texture if it's non pow2.

KeepBitmap = BIT(7)

Always keep a copy of this texture's bitmap. (Potentially in addition to the API managed copy?).

ZTarget = BIT(8)

This texture will be used as a Z target.

enum Constants {

These constants control the packing for the profile; if you add flags, types, or compression info then make sure these are giving enough bits! More...
