class (GObject o, IsDescendantOf MemoryTexture o) => IsMemoryTexture o

Type class for types which can be safely cast to MemoryTexture, for instance with toMemoryTexture.

Instances

(GObject o, IsDescendantOf MemoryTexture o) => IsMemoryTexture o

Defined in GI.Gdk.Objects.MemoryTexture

toMemoryTexture :: (MonadIO m, IsMemoryTexture o) => o -> m MemoryTexture

Cast to MemoryTexture, for types for which this is known to be safe. For general casts, use castTo.

Arguments

:: (HasCallStack, MonadIO m)

=> Int32

width: the width of the texture

-> Int32

height: the height of the texture

-> MemoryFormat

format: the format of the data

-> Bytes

bytes: the GBytes containing the pixel data

-> Word64

stride: rowstride for the data

-> m MemoryTexture

Returns: A newly-created GdkTexture

Creates a new texture for a blob of image data.

The GBytes must contain stride x height pixels in the given format.
