GSoC 2018, Week 4

Made few commits and submitted code with a few bugs left with the rendering of the painter due to QWidget.

June 8, 2018

Made a from changes in painter workflow. Now draw the line, rectangle, etc. will store instructions to draw particular patterns in form of drawing lines between two coordinates. Once stroke function is called all the data that is stored is drawn.

June 5-6, 2018

Removing the instances of the previous painter and working on rendering new painter.

June 4, 2018

Creating another function for the check of repeated drawing of the same pattern. So it stores the pattern in GPU cache and calls ‘glDrawArray’ to draw pattern instead of drawing it again.

June 4, 2018

Once the pattern is saved then dashes are rendered using stroke function by drawing the line for the ‘on’ part and draw nothing for the ‘off’ part.

June 3, 2018

Started working on the dash patterns. As no OpenGL libraries work on rendering dashes considering the line width and offset. For set_dash creating an array for storing the dash lengths with offset.
