I'm designing a drawing program in matlab (just imagine a simplified Photoshop), where the paintbrush can have larger than 16-by-16 size. I'd like to customize the pointer such that it has exactly the same size and same shape as the paintbrush (e.g. circle). Right now, I can change the shape by customizing PointershapeCData:
But the cdata is limited to 16-by-16, otherwise there will be a error. It seems matlab doesn't support any other sizes.
Is there anyway that I can make the pointer larger than 16-by-16?
Thank you very much in advance!
