Hi!
We are using the current release of DECwindows to draw some small
circles, using the XDrawArc and XFillArc calls. Since this version is
based on R3, I'm wondering if the R4 versions of these routines have
improved? The problem with the current version of XFillArc is that small
circles, less than 10 pixels or so, actually appear as squares (verified
using a magnifier program). XDrawArc seems to do a better job of drawing
open circles at smaller sizes - can I draw it using XDrawArc and fill it
some other way? I'm thinking about writing my own arc-drawing routine
using a different algorithm.
Is this a recognized problem with R3? Has it been corrected in R4?
Has anyone implemented their own algorithm that they would be able to share?
Email to me and I will email a summary to those who request the info.
