IMDraw is an immediate-mode-like shape drawer and BasicTarget. IMDraw supports TrianglesPosition, TrianglesColor, TrianglesPicture and PictureColor.
IMDraw, other than a regular BasicTarget, is used to draw shapes. To draw shapes, you first need to Push some points to IMDraw:
imd := pixel.NewIMDraw(pic) use nil pic if you only want to draw primitive shapes
imd.Push(pixel.V(100, 100))
imd.Push(pixel.V(500, 100))Once you have Pushed some points, you can use them to draw a shape, such as a line:
`imd.Line(20) //draws a 20 units thick line``
Set exported fields to change properties of Pushed points:
imd.Color = pixel.RGB(1, 0, 0)
imd.Push(pixel.V(200, 200))
imd.Circle(400, 0)Here is the list of all available point properties (need to be set before Pushing a point):
- Color - applies to all
- Picture - coordinates, only applies to filled polygons
- Intensity - picture intensity, only applies to filled polygons
- Precision - curve drawing precision, only applies to circles and ellipses
- EndShape - shape of the end of a line, only applies to lines and outlines
And here's the list of all shapes that can be drawn (all, except for line, can be filled or outlined):
- Line
- Polygon
- Circle
- Circle arc
- Ellipse
- Ellipse arc
