+# IMDraw
+
+<hr>
+ 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:
+```go
+   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:
+
+```go
+   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
