wxPdfDocument Calculating Text Height

Post by Everydaydiesel » Sun Aug 19, 2018 1:25 am

Hello,

I see a GetStringWidth but I do not see one for height? Am I missing it?


Thanks again!

The method you are seeking for is GetFontSize. This method returns the size of the currently selected font in points, where 1 point equals 1/72 inch. It is not necessary to calculate the text height of a text string, because it is determined by the font size.

For readable text output the line height should typically be about 25 % higher than the font size.

If you need more details about the currently selected font, you can use method GetDescription of the wxPdfFont class, which returns a wxPdfFontDescription object.

Regards,

Ulrich
