A function to align points for a certain rendering device.

data AlignmentFns Source #

Holds the point and coordinate alignment function.

Constructors

AlignmentFns

Fields

afPointAlignFn :: AlignmentFn
An adjustment applied immediately prior to points being displayed in device coordinates.
When device coordinates correspond to pixels, a cleaner image is created if this transform rounds to the nearest pixel. With higher-resolution output, this transform can just be the identity function.
This is usually used to align prior to stroking.
afCoordAlignFn :: AlignmentFn
The adjustment applied immediately prior to coordinates being transformed.
This is usually used to align prior to filling.

bitmapAlignmentFns :: AlignmentFns Source #

Alignment to render on raster based graphics.

vectorAlignmentFns :: AlignmentFns Source #

Alignment to render on vector based graphics.
