How to draw a curved rectangle matrix with given two points?
Assume, two points given:
a = [1,0.5];
b = [1,3.5];
And the created curved rectangle should be like this:
But the point is, all I finally want, is an image matrix return, not just to plot this figure using rectangle(); on screen.
Thanks, guys~
ps: in a binary scale.

If you want an image matrix, I still suggest using rectangle() to first draw, then exporting the figure to bitmap for getting the image matrix.


Hi Joachim, Thanks for your answer, It would work if I use getframe() converting figure to matrix, but it seems lack of efficiency, in which the speed is chief consideration. I found insertShape() could insert image to matrix, but I failed even with times trying. Would you mind help me with this?
insertShape cannot directly draw rounded rectangles. You may first want to try the above solution using
to disable the display of the figure and thus drastically increase speed.
