Line (const Path &p, const LineAttr &line)ĭraw an arbitrary Path using the line & corner style in line Line (const Block &b, const LineAttr &line)ĭraw a rectangle line (perhaps with corners) using the line & corner style in line Line (const XY &s, const XY &d, const LineAttr &line)ĭraw a straight line from s to d using the line style in line Line (const Edge &edge, const LineAttr &line)ĭraw a line along edge using the line style in line Restore the original canvas after a transformation. Transform the canvas by flipping it along the horizontal line at y. Transform the canvas by swapping x and y coordinates. Transform_Rotate90 (double s, double d, bool clockwise) Rotates the canvas to arbitrary degree around 'center' Any arrow drawn from left to right will show up as rotated clockwise with y coordinate growing downwards.

Set the line cap style & return previous one. Set the line join style & return previous one. True if we should avoid transparency when drawing. True if the target has disappearing lines. True if the target has imprecise positioning.
True if the target does not support complex clipping. Return the current cairo context for direct manipulation. More.įlush output, write to file and close canvas. Switches to the second drawing situation allowing to draw header (inserted by e.g., automatic pagination) and footer (copyrgight text).
