Documentation
type Point = (Float, Float)Source
A point on the x-y plane.
Points can also be treated as Vectors, so Graphics.Gloss.Data.Vector may also be useful.
A 2D picture
Constructors
| Blank | A blank picture, with nothing in it. |
| Polygon Path | A 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 |
| Text String | Some text to draw with a vector font. |
| Bitmap Int Int ByteString | A bitmap image with a width, height and a ByteString holding the 32 bit RGBA bitmap data. |
| 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 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. |
