[RESOLVED] Graphics.RotateTransform for vertical aligned Text

[boops boops]

You came too late with the VB version, but never mind, I braved the shark-infested waters of Csharp to take a look. TextRenderingHint.Antialias (without GridFit!) seems to give better diagonals and curves, but the straight lines become slightly irregular (on my screen). Sans-Serif fonts do better than Serif ones such as in your post above. Making the font slightly larger helps a lot -- 9 points is enough for Microsoft Sans Serif. I suspect that this is as good as you are going to get in WinForms. FWIW, WPF is reputed to be better at sub-pixel rendering. BB

Thanks BB!
I think you have the right of it; I'm going to leave this open for a bit more to see if anyone else has any other insight.

I'll look into WPF.

I can think of a couple of other possibilities that would be interesting to experiment with, although I don't have time at the moment,

1. Create a text path with GraphicsPath.AddString, rotate the path with its own matrix argument, then render the text with Graphics.Drawpath or Graphics.FillPath.

2. Render the text horizontally to a bitmap, then draw the bitmap rotated with Graphics.DrawImage.

3. Render the text to a bitmap at double the target size, then draw the bitmap reduced to the target size with Graphics.DrawImage.

I would be surprised if 1 offers much if any benefit, but I think 2 combined with 3 could well give an improved result for small text.

I've not had much success with vertical rendering of text, not that I have done it much. However, my preference is to render text to an image and draw a rotated image. It seems to work for me, anyway, since I'm not a big fan of vertical text so don't do much of it.
