Graphics.HGL.Draw.Font

Description

Text fonts.

Portability notes:

X11 does not directly support font rotation so createFont and mkFont 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.

Synopsis

Documentation

data Font Source

createFont Source

Arguments

:: 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 Font Source

Set the font for subsequent text, and return the previous font.

mkFont Source

Arguments

:: 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).
