Documentation
isRenderTargettable :: ImageFormat -> Bool Source
Given a format, returns True if that format can be rendered to. That is,
if it can be one of the targets in a framebuffer.
This is conservative. Sometimes you may be able to render anyway; however this is not guaranteed by the OpenGL specification.
isCompressed :: ImageFormat -> Bool Source
Returns true if the given format is a compressed format.
isColorFormat :: ImageFormat -> Bool Source
Returns true if the given format is a color format.
hasDepthComponent :: ImageFormat -> Bool Source
Returns true if the given format has a depth component.
hasStencilComponent :: ImageFormat -> Bool Source
Returns true if the given format has a stencil component.
isSRGBFormat :: ImageFormat -> Bool Source
Returns true if the given format uses the sRGB color space.
If the format is not a color format, returns False.
data ImageFormat Source
All the various internal formats.
This list corresponds to the OpenGL specification of 3.3, required texture formats (+ S3TC compressed formats). Check the OpenGL specification for explanations on how these formats work.
Constructors
toConstantIF :: ImageFormat -> GLenum Source
data SpecificationType Source
Specification formats.
These formats specify the type of the data passed from Haskell to GPU.
sizeOfSpecificationType :: SpecificationType -> Int Source
Given a specification format, returns the number of bytes one element uses.
class SpecificationTypeable a where Source
Class that turns Haskell types into SpecificationType.
Methods
Arguments
| :: a | Used to pass the type; not evaluated. |
| -> SpecificationType |
Returns the corresponding SpecificationType for a Haskell type.
