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

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

Instances

(BoxedPtr o, TypedObject o, IsDescendantOf Bitmap o) => IsBitmap o

Defined in GI.Cogl.Objects.Bitmap

toBitmap :: (MonadIO m, IsBitmap o) => o -> m Bitmap

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

Methods

getSizeFromFile

bitmapGetSizeFromFile

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

newFromFile

bitmapNewFromFile

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.
