How can I change a canvas created in units of mm to px?
If you created your canvas in a large size such as 1600 mm, then operations such as drawing may become slower.

If you are creating a work for printing, such as A4 size, your work may become smaller than the required print size by following the process on this page to shrink your canvas.
