The wand.drawing module provides some basic drawing functions. wand.drawing.Drawing object buffers instructions for drawing shapes into images, and then it can draw these shapes into zero or more images. It's also callable and takes an Image object:This is done by creating a Vertex Buffer Object (VBO): GLuint vbo; glGenBuffers ( 1, &vbo); // Generate 1 buffer. The memory is managed by OpenGL, so instead of a pointer you get a positive number as a reference to it. GLuint is simply a cross-platform substitute for unsigned int, just like GLint is one for int. Polygons are some of the first shapes we learn to draw as children, and they appear all around us. Polygons can be regular or irregular. They can be simple or complex, convex or concave. They can be the familiar shapes you see in geometry textbooks, or they can be strange shapes, like darts and bowties.If necessary, click the drop-down arrow next to Date line correction and choose True for drawing the polygon across the line of 180° longitude.

The boundary is created by connecting a line from one point to the next, with the last point connected to the first point. The Points property defines the collection of points that make up the boundary. In XAML, you define the points with a comma-separated list.To draw a semi-transparent polygon on top of img, make a copy of the image. One the copy, draw the polygon in full color without alpha. Then use Image.blend to combine the original image with the copy with a set level of alpha. For each pixel: out = image1 * (1.0 - alpha) + image2 * alpha. Share.How can I produce a polygon which is just the extent of the raster image? That is, I want to have a polygon layer with a single quadrilateral which is the edge of the image.
