Documentation

data Picture :: *

A 2D picture

Constructors

Blank

A blank picture, with nothing in it.

Polygon Path

A convex polygon filled with a solid color.

Line Path

A line along an arbitrary path.

Circle Float

A circle with the given radius.

ThickCircle Float Float

A circle with the given thickness and radius. If the thickness is 0 then this is equivalent to Circle.

Arc Float Float Float

A circular arc drawn counter-clockwise between two angles (in degrees) at the given radius.

ThickArc Float Float Float Float

A circular arc drawn counter-clockwise between two angles (in degrees), with the given radius and thickness. If the thickness is 0 then this is equivalent to Arc.

Text String

Some text to draw with a vector font.

Bitmap Int Int BitmapData Bool

A bitmap image with a width, height and some 32-bit RGBA bitmap data.

The boolean flag controls whether Gloss should cache the data in GPU memory between frames. If you are programatically generating the image for each frame then use False. If you have loaded it from a file then use True. Setting False for static images will make rendering slower than it needs to be. Setting True for dynamically generated images will cause a GPU memory leak.

Color Color Picture

A picture drawn with this color.

Translate Float Float Picture

A picture translated by the given x and y coordinates.

Rotate Float Picture

A picture rotated clockwise by the given angle (in degrees).

Scale Float Float Picture

A picture scaled by the given x and y factors.

Pictures [Picture]

A picture consisting of several others.

A convex polygon filled with a solid color.

line :: Path -> Picture

A line along an arbitrary path.

circle :: Float -> Picture
