Hi folks, Last few days I am trying to solve very strange puzzle - how to draw FULL attributed string.
Short story: I have a NSTextStorage object, which holds my formatted string information. I am editing it via NSTextView (NSLayoutManager + NSTextContainer + my NSTextStorage) mechanism. That works great until I am dealing with drawing. To find out rect, which will be required to fit my text, I am using - (NSRect)usedRectForTextContainer:(NSTextContainer *)aTextContainer of NSLayoutManager. To draw actual content I am using drawBackgroundForGlyphRange:(NSRange)glyphsToShow atPoint:(NSPoint)origin and drawGlyphsForGlyphRange:(NSRange)glyphsToShow atPoint:(NSPoint)origin from the same NSLayoutManager. And that works great for 90% of time. But I need 100%. Problem: Actually I am dealing with two drawing problems: 1. When my attributed string (NSTextStorage) has a shadow, made by using Fonts panel, it is NOT INCLUDED when trying to find out used rect by calling [myLayoutManager usedRectForTextContainer:myTextContainer]. Never. The situation can be easily demonstrated with TextEdit: https://www.dropbox.com/s/vt21zpq46xl0gb5/Text-with-cropped-shadow.png . The same I am getting in my app. But I need a shadow, therefor I have set it. To draw it correctly, I need a bounding (used) rect, which counts in a shadow attribute. Is it possible at all using cocoa text system? 2. With some fonts (for example Eccentric Std, Palemonas, some others which i can't remember right now) the [myLayoutManager usedRectForTextContainer:myTextContainer] returns rect which does not covers WHOLE text. Sometimes diacritic symbols of the very top line are missing (https://www.dropbox.com/s/dpjjugzxcnp771r/Missing-diacrytic-symbol.png <- both letters are the same "Alt + e + e = é" combination), sometimes the first left symbol is cropped (https://www.dropbox.com/s/33mfgoqwbgwcvg1/Cropped-left-side-1.png, https://www.dropbox.com/s/kbgfdzuhcr1svht/Cropped-left-side-2.png, https://www.dropbox.com/s/ntxgufl8e562uep/Cropped-left-side-3.png). Question is the same - how to get rect, which would fit my whole text. Any help is very appreciate. p.s. don't hesitate to ask for an additional information. I could even make a small sample app if required.
