I’m using GDI+ in C++. (This issue might exist in C# too).

I notice that whenever I call Graphics::MeasureString() or Graphics::DrawString(), the string is padded with blank space on the left and right.

For example, if I am using a Courier font, (not italic!) and I measure ‘P’ I get 90, but ‘PP’ gives me 150. I would expect a monospace font to give exactly double the width for ‘PP’.

My question is: is this intended or documented behaviour, and how do I disable this? 

RectF Rect(0,0,32767,32767); RectF Bounds1, Bounds2; graphics->MeasureString(L'PP', 1, font, Rect, &Bounds1); graphics->MeasureString(L'PP', 2, font, Rect, &Bounds2); margin = Bounds1.Width * 2 - Bounds2.Width;

  1. It’s by design, that method doesn’t use the actual glyphs to measure the width and so adds a little padding in the case of overhangs.

    MSDN suggests using a different method if you need more accuracy:

    To obtain metrics suitable for adjacent strings in layout (for example, when implementing formatted text), use the MeasureCharacterRanges method or one of the MeasureString methods that takes a StringFormat, and pass GenericTypographic. Also, ensure the TextRenderingHint for the Graphics is AntiAlias.
