When drawing text strings with the help of Graphics Mill and using the ITC Stone Sans Semibold font, an exception may occur, or the text may be drawn using a different font.DescriptionIf you draw text using Graphics Mill for .NET, and try to use
ITC Stone Sans Semibold font, it may produce an exception, or the text may be drawn using some other different font. In the same time it may work properly on other computers.
The typical symptom of a problem when you draw text through GDI (
Aurigma.GraphicsMill.Drawing.GdiGraphics class) is the
Aurigma.GraphicsMill.Win32Exception exception which occurs whenever you try to draw a text with this font. Text of the exception will look similar to the follows:
Code:************** Exception Text **************
Aurigma.GraphicsMill.Win32Exception: GetCharacterPlacement call failed
at Aurigma.GraphicsMill.Drawing.GdiGraphics._DrawString(String s, Font font, SolidBrush brush, Single x, Single y, Single[] kernings)
at Aurigma.GraphicsMill.Drawing.GdiGraphics.DrawString(String s, Font font, SolidBrush brush, Int32 x, Int32 y)
at WindowsApplication1.Form1.button3_Click(Object sender, EventArgs e)...
If you try to draw some text using GDI+ (i.e. using standard .NET class, namely
System.Drawing.Graphics), no exception will occur. However, the text may not be rendered correctly, as the acually used font may differ from ITC Stone Sans Semibold.
Reason
The reason of this behavior is a bug of GDI and GDI+.
SolutionCurrently, the only solution is to render the text using another font. In particular, it is recommended to handle
the
Aurigma.GraphicsMill.Win32Exception exception, and if it is raised, use some fallback font.
