Better Image Quality of Cursor Icons

@Vector-Rock I add this to the backlog. Is this on Windows or Mac?
@vectoradmin,
This is on macOS (Intel).

@Vector-Rock A bit of (technical) explanation:
VS cursors are defined as vector shapes. This has some advantages like easy to customize size and rotation. And of course, these are all done in VS.For example the rotate cursor (when hovering just outside of the transform tool box corner) changes its angle to the current box rotation. This is a single cursor, shown with varying rotation.
But, creating small images from vectors (at the required cursor size of the OS) can be challenging. This is why fonts need hinting at small size. But there is no hinting for these cursor.
Of course for each cursor there is a cursor drawing and then a mask drawing which most of the time is just the expanded version of the cursor. I will try to use larger expansion.

@vectoradmin
Thanks for the information.
Of course I knew that that size was a challenging factor.
I guess a combination of know-how and trial and error is the required recipe to find the best solution.
It would be interesting to know how the CorelDRAW engineer handled this.
-
@Vector-Rock To my understanding, most (if not all) application cursors are drawn as image resources (basic bitmaps).
All software frameworks (both on Mac and Windows, but also others) require that cursors are given as images.
This means that each cursor can be handcrafted to the detail to look good. -
@vectoradmin MacOS has a default display resolution of 72 ppi. Maybe the vector-based resources for these cursors don't snap correctly to a 72-ppi-based grid? Maybe the black line is less than 2 pixels (say, 1.7 px) and the white contour is again somewhere in between integer values.

The 72ppi assumption dates back to the pre-Retina days. No longer a safe assumption.

@fde101 Sure, but 144 is still "compatible" with 72, so to speak. It's not 90 or 96 or whatever other ppi value.
-
144 is not safe either:

Cursor quality has been improved in build 1.0.045

@vectoradmin Indeed it has. Great!
