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 radius and thickness. 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 BitmapData | A bitmap image.
BitmapSection Rectangle BitmapData | A subsection of a bitmap image where the first argument selects a sub section in the bitmap, and second argument determines the 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 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.
