Text fonts.
Portability notes:
- X11 does not directly support font rotation so
createFont
andmkFont
always ignore the rotation angle argument in the X11 implementation of this library. - Many of the font families typically available on Win32 are not available on X11 (and vice-versa). In our experience, the font families courier, helvetica and times are somewhat portable.

:: Size | size of character glyphs in pixels |
-> Angle | rotation angle |
-> Bool | bold font? |
-> Bool | italic font? |
-> String | font family |
-> IO Font |
Create a font.
The rotation angle is ignored if the font is not a "TrueType" font
(e.g., a System
font on Win32).
deleteFont :: Font -> IO ()Source
Delete a font created with createFont
.
selectFont :: Font -> Draw FontSource
Set the font for subsequent text, and return the previous font.
:: Size | size of character glyphs in pixels |
-> Angle | rotation angle |
-> Bool | bold font? |
-> Bool | italic font? |
-> String | font family |
-> (Font -> Draw a) | |
-> Draw a |
Generate a font for use in a drawing, and delete it afterwards.
The rotation angle is ignored if the font is not a "TrueType" font
(e.g., a System
font on Win32).
