  What was once working, now throws a “Index was outside the bounds of the array” for certain fonts.
  
  I’m sure these fonts aren’t perfect, because users upload the fonts. But it was working, and now it throws an error.

  If I change the font, it appears to work properly, but this is the stack trace when the error is thrown:

     at GrapeCity.Documents.Q.amp.y()
     at GrapeCity.Documents.Q.amp.i(Int32 a)
     at GrapeCity.Documents.Q.amp.e(b a, Int32 b, Boolean c, Boolean d)
     at GrapeCity.Documents.Imaging.BitmapRenderer.aw(FontTables a, Int32 b, amp c)
     at GrapeCity.Documents.Imaging.BitmapRenderer.an(GlyphRun a, amp b, FontTables c, Single d, Single e, Single f, Int32 g)
     at GrapeCity.Documents.Imaging.BitmapRenderer.ai(TextLayout a, Single b, TextLine c, Single d, Single e, RectangleF f, List`1 g, List`1 h)
     at GrapeCity.Documents.Imaging.BitmapRenderer.DrawTextLayout(TextLayout layout, Single x, Single y)
     at GrapeCity.Documents.Imaging.GcBitmapGraphics.InternalDrawTextLayout(TextLayout layout, PointF location)
     at GrapeCity.Documents.Drawing.GcGraphics.DrawTextLayout(TextLayout layout, PointF location)

  Hi,

  We are unable to replicate this issue at our end. Could you please provide more information?

  1. Version of DsImaging library.
  2. In which operation you are getting this error? While opening Image, saving image, etc.
  3. Provide the Fonts which causing this error.
  4. Provide a stripped .Net sample replicating this issue. So we can investigate this issue and assist you better.

  Regards,

  1. I’m using DS.Documents.Imaging (7.1.4)
  2. The exception happens at g.DrawTextLayout();
  3. Attached the font

  var grapeText = new TextFormat {
      FontSize = 120,
      ForeColor = Color.White,
      FontStyle = GrapeCity.Documents.Text.FontStyle.Regular,
      FontBold = false,
      FontItalic = false,
      Underline = false,
      UseTypoMetrics = true,
      FontSizeInGraphicUnits = true,
      Font = GrapeCity.Documents.Text.Font.FromArray(request.FontBytes)
  };
  
  var size = getFontSize(request.Text, grapeText);
  
  using var bmp = new GcBitmap((int)size.Width, (int)size.Height, false);
  bmp.SetDpi(96);
  
  using var g = bmp.CreateGraphics(Color.Black);
  
  var tl = g.CreateTextLayout();
  tl.TrimmingGranularity = TrimmingGranularity.Character;
  tl.WrapMode = WrapMode.WordWrap;
  
  tl.Append(request.Text, grapeText);
  
  g.DrawTextLayout(tl, new PointF(0, 0))

  This worked in an older version of your library, when it was GrapeCity, but we’re updating our project to .NET Core and now are forced to use the latest versions.

  Hi,

  Thanks for the information. We have replicated this issue at our end. This seems like a bug in the latest versions.
  
  We have escalated this to the development team. Will get back to you once we have any updates from them.[Internal Tracking Id - DOC-6470]

  I saw that an update came out today (DS.Documents.Imaging 7.2).
  
  I’m not sure if that was intended to fix the bug because the documentation only says “New Features and Improvements”…but it did not.

  Looking forward to the fix, and if I can make another request. I’d love to see a list of the new features and improvements for each update. Depending on the feature or update, there’s an opportunity for us to offer new functionality to our clients, making your component more valuable to us (just a thought).

  Hi,

  As per the development team, this issue will be addressed in the upcoming build 7.2.1 version. However, there is a workaround to fix this issue. You can set Font.EnableHinting = false for the TextFormat.

  Please refer the attached working sample: ImageDemo.zip
