I'm using the Font.MeasureString to get the metrics of custom TTFs. Here's the code I'm using: Code:
public static Size GetFontSize(string textToMeasure) {
using (var bitmap = new Bitmap(100, 100, PixelFormat.Format32bppArgb, RgbColor.Blue))
using (var graphics = bitmap.GetAdvancedGraphics())
using (var customFont = new CustomFontRegistry()) {
bitmap.DpiX = 96;
bitmap.DpiY = 96;
customFont.Add(@"C:\Users\blind\Desktop\3062.ttf");
graphics.FontRegistry = customFont;
var font = graphics.CreateFont(customFont.Fonts[0].PostscriptName, 50);
var size = font.MeasureString(textToMeasure);
return new Size() {
Height = Convert.ToInt32(size.Height),
Width = Convert.ToInt32(size.Width)
};
}
}
When I use the character ":" my debug session ends and my CPU goes to 100%. Now I've looked into this font, and it appears that it doesn't contain that specific character. Our users upload their own fonts, so I can't just ignore this issue, is there a way for me to determine that the character doesn't exist in the TTF? I'd be OK with your SDK throwing an error and me trapping it, or if you returned Null or a size of 0....but it just goes haywire. Any suggestions?  3062.zip (9kb) downloaded 7 time(s).

We successfully reproduced the problem of 100% CPU usage and will fix it shortly (Aurigma Bug #0023431). I will keep you informed of the status.

We support font fallback, but unfortunately it is not possible to check whether a character is implemented in a font. We plan to implement this functionality in the further releases (Aurigma Bug #0022479). Code:customFont.Add("3062.ttf");
customFont.Add("ARIALUNI.TTF");
customFont.FallbackFonts.Add("Arial Unicode MS");
