Drawing to wxGraphicsContext in native resolution on retina screens

[Stefan Csomor]

Hi Joost

wxAutoBufferedPaintDC would be the thing to use, this is using a buffered dc on platforms where needed, and a plain paintdc on already buffered platforms ...

Best,

Stefan

I found the problem!
I was creating the wxGraphicsContext from a wxBufferedPaintDC. After changing this to wxPaintDC everything comes out crisp. Which is fine because buffering isn't needed on mac anyway.

Again thanks for the help!

drawing text definitely should not be done without antialiasing / smoothing on OSX, for drawing paths the outcome depends on the coordinates and thickness, also bitmaps should always align on the pixels boundaries, but all these situations should actually be better on Retina, not worse, so I still assume the issue is some intermediate format ...

I found that wxGraphicsContext had anti-aliasing enabled by default, which made my drawing code look blurry. Try disabling it:

SetAntialiasMode( wxANTIALIAS_NONE );

Hi,

Currently all text and images drawn to a wxGraphicsContext on macs with retina screens come out blurred. Is there any way to get a wxGraphicsContext at the native screen resolution? I'm prepared to call OS X apis if necessary and do the scaling myself Does anyone know a way to do this?

Thanks
Joost

drawing text definitely should not be done without antialiasing /
smoothing on OSX, for drawing paths the outcome depends on the coordinates
and thickness, also bitmaps should always align on the pixels boundaries,
but all these situations should actually be better on Retina, not worse, so
I still assume the issue is some intermediate format

I just tried to configure wx (both 2.8 and 3.0.1) with
--disable-mediactrl. "wx-config --libs" still has "-framework QuickTime"
in it. Is there something else that needs to be done? Or is that just a
bug in wx-config?

I've applied a blind fix for this in r76800, please let me know if it
works for you and I'll backport it to 3.0 then.

TIA,

Looks good. No qt framework option in the --libs output.

as the now living build bot now reports failure, I think you have to leave
this in for carbon builds

Thanks,

Yes, indeed, there doesn't seem to be any reason to not do it there
anyhow. Should be fixed now, thanks!
