Problem with text rendering in high resolution?

[drewish]

I noticed that one of the samples have settings->setHighDensityDisplayEnabled(); but one app has it commented out.

Disabled:

Enabled:

Text seems equally blurry in both cases but in the enabled case it seems more desaturated.

Curious if you've any idea what's going on with it.

Will take a look. Pretzel is due for some sprucing up overall, this is a good place to start

I wonder if it's just a a problem with TextureFont. i started testing out TextureFontApp and it seems to be similarly afflicted at smaller sizes. I posted some screenshots on: http://discourse.libcinder.org/t/pixalated-font-on-retina-display/435/5

Something like https://github.com/chaoticbob/Cinder-SdfText might give better results but I'm not sure it'd make sense to have this block depending that.

A hacky solution might be to draw the type twice as large and draw it at 50% if that's the case.

yeah if that'd fix it, it seems like something the TextureFont should be doing. i'll try to do some experimentation since i've got another feature i'm working on that needs to do some text rendering.

Hi,
Change these lines in renderTextInternal(PretzelGlobal.cpp)

guiFont->drawString(text, ci::vec2(-textSize.x, 0) + pos + ci::vec2(0,emHeight), opts); guiFont->drawString(text, ci::vec2((int)textSize.x*-0.5, 0) + pos + ci::vec2(0,emHeight), opts); guiFont->drawString(text, pos + vec2(0,emHeight), opts); ci::Font tmp("Arial", 16); emHeight = floor( guiFont->measureString("M").y );

to this

guiFont->drawString(text, ci::vec2(-textSize.x * 0.65, 0) + pos + ci::vec2(0,emHeight),gl::TextureFont::DrawOptions().scale( 0.5f ).pixelSnap( false ) ); guiFont->drawString(text, ci::vec2((int)textSize.x*-0.5, 0) + pos + ci::vec2(0,emHeight),gl::TextureFont::DrawOptions().scale( 0.5f ).pixelSnap( false ) ); guiFont->drawString(text, pos + vec2(0,emHeight), gl::TextureFont::DrawOptions().scale( 0.5f ).pixelSnap( false ) ); ci::Font tmp("Arial", 21); emHeight = floor( guiFont->measureString("M").y * 0.55 );
