Whey is there a white value where the two lines cross in this example, and how can I keep it the color specified in InsertShape?
clear all
pzzz = 255 - uint8(zeros(200,200,3)); % DOUBLE TO UINT8
pzzz = insertShape(pzzz,'Polygon', [1 100 200 1, 10 10 150 150],...
Color=[0 0 0], LineWidth=5, Opacity=1);
imagesc(pzzz)

I guess you could just plot one line at a time.

I have hundreds of lines to draw, but I'll see if it works to draw each one separately.

Ok, yes it works, I will have to make a loop to draw all the lines individually, I guess.
