conflict between Core Graphics and NSView graphics

hi all i converted a bunch of quickdraw code to core graphics successfully -- it worked now i am converting a bunch of carbon UI code to cocoa but when I draw text, my fonts are wrong and my font sizes are much too big i am getting the CGContextRef from the NSWindow in the drawRect handler,

Bill, How are you rendering the text ? We recommend sticking to Cocoa text rendering API in order to support proper Unicode rendering. Thanks, Aki On Apr 26, 2010, at 12:24 PM, Bill Appleton wrote: hi all i converted a bunch of quickdraw code to core graphics successfully -- it worked

hi Aki, i am using CGContextShowGlyphsWithAdvances i have a very large amount of core graphics code, i thought it was compatible with cocoa i see the text in the right spot but the size is gigantic thanks, bill On Mon, Apr 26, 2010 at 12:34 PM, Aki Inoue a...@apple.com wrote: Bill,

Re: conflict between Core Graphics and NSView graphics

OK, sounds like you're being affected by the text matrix. In CG, there are 3 font properties that determine the font rendering: font name, font size, and text matrix. You need to manage all 3. The easiest approach is to use -[NSFont setInContext:] to let the Cocoa object set all 3 properties

Re: conflict between Core Graphics and NSView graphics

We always us the text matrix instead of font size. While it is true that the advancements and glyph outline could be affected by the font point size down in the font system, the CG graphics model doesn't work that way. What we recommend is to stick to the Cocoa Text System that tries very hard

Re: conflict between Core Graphics and NSView graphics

that CGContextRef is the same as [[thewind graphicsContext] graphicsPort] in the scope if the drawRect routine (i am away from that machine, the code is probably wrong, but you can see what i mean) so the two methods return the same context On Mon, Apr 26, 2010 at 3:58 PM, Mike Abdullah
