lots of variations for controlling the image: resolution, colorspace, transparency, rotation, mirroring, shifting, shearing, etc. Saving the Page Image in a File We can simply store the image in a PNG – end point. Return type: Point Returns: the end point, p3. Example: a filled quarter ellipse segment. drawSector(center, point, angle, fullSector = True) Draw a circular sector, optionally connecting center (Point) – the center of the circle. point (Point) – one of the two end points of the pie’s arc segment. The other one is calculated from the angle. angle (float) – the angle of the sector in degrees.

produce a grayscale image or an image with a subtractive color scheme), transparency, rotation, mirroring, shifting, shearing, etc. For example: to create an RGBA image (i.e. containing an alpha channel) i.e. its appearance can be changed via a Matrix, to achieve effects like scaling, shearing or mirroring, – independently from morphing and in addition to that, text can be rotated by integer multiples list containing required parameters.
