SetFont -- Set the text font and attributes in a RastPort.
SetFont(rp, font)
A1 A0
void SetFont(struct RastPort *, struct TextFont *);
This function sets the font in the RastPort to that described
by font, and updates the text attributes to reflect that
change. This function clears the effect of any previous
soft styles.
rp - the RastPort in which the text attributes are to be changed
font - pointer to a TextFont structure returned from OpenFont()
or OpenDiskFont()
This function had previously been documented that it would
accept a null font. This practice is discouraged.
o Use of a RastPort with a null font with text routines has
always been incorrect and risked the guru.
o Keeping an obsolete font pointer in the RastPort is no more
dangerous than keeping a zero one there.
o SetFont(rp, 0) causes spurious low memory accesses under
some system software releases.
As of V36, the following Amiga font variants are no longer
directly supported:
fonts with NULL tf_CharSpace and non-NULL tf_CharKern.
fonts with non-NULL tf_CharSpace and NULL tf_CharKern.
fonts with NULL tf_CharSpace and NULL tf_CharKern with
a tf_CharLoc size component greater than tf_XSize.
Attempts to SetFont these one of these font variants will
cause the system to modify your font to make it acceptable.
Calling SetFont() on in-code TextFonts (ie fonts not
OpenFont()ed) will result in a loss of 24 bytes from
the system as of V36.
This can be resolved by calling StripFont().
