GI.Gdk.Objects.MemoryTexture
Contents
Description
A GdkTexture representing image data in memory.
Synopsis
- newtype MemoryTexture = MemoryTexture (ManagedPtr MemoryTexture)
- class (GObject o, IsDescendantOf MemoryTexture o) => IsMemoryTexture o
- toMemoryTexture :: (MonadIO m, IsMemoryTexture o) => o -> m MemoryTexture
- type family ResolveMemoryTextureMethod (t :: Symbol) o where ...
- memoryTextureNew :: (HasCallStack, MonadIO m) => Int32 -> Int32 -> MemoryFormat -> Bytes -> CSize -> m MemoryTexture
Exported types
newtype MemoryTexture Source #
Memory-managed wrapper type.
Constructors
| MemoryTexture (ManagedPtr MemoryTexture) |
Instances
class (GObject o, IsDescendantOf MemoryTexture o) => IsMemoryTexture o Source #
Type class for types which can be safely cast to MemoryTexture, for instance with toMemoryTexture.
Instances
| (GObject o, IsDescendantOf MemoryTexture o) => IsMemoryTexture o Source # | |
Defined in GI.Gdk.Objects.MemoryTexture | |
toMemoryTexture :: (MonadIO m, IsMemoryTexture o) => o -> m MemoryTexture Source #
Cast to MemoryTexture, for types for which this is known to be safe. For general casts, use castTo.

Arguments
| :: (HasCallStack, MonadIO m) | |
| => Int32 |
|
| -> Int32 |
|
| -> MemoryFormat |
|
| -> Bytes |
|
| -> CSize |
|
| -> m MemoryTexture | Returns: A newly-created |
Creates a new texture for a blob of image data.
The GBytes must contain stride × height pixels
in the given format.
