class (BoxedPtr o, TypedObject o, IsDescendantOf Bitmap o) => IsBitmap o Source #

Type class for types which can be safely cast to Bitmap, for instance with toBitmap.

Instances details

(BoxedPtr o, TypedObject o, IsDescendantOf Bitmap o) => IsBitmap o Source #
Instance details Defined in GI.Cogl.Objects.Bitmap

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

Methods

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`filename`: the file to check
-> m (Int32, Int32, Int32)	Returns: `True` if the image was successfully parsed

Parses an image file enough to extract the width and height of the bitmap.

Since: 1.0

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`filename`: the file to load.
-> m Bitmap	Returns: a `Bitmap` to the new loaded image data, or `Nothing` if loading the image failed. (Can throw `GError`)

Loads an image file from disk. This function can be safely called from within a thread.
