points
Character size in points (1/72nd inch) or pixels
Description
The routine gSetCharSizePoint() sets the point size of subsequent characters and is used on Windows and Windows-based devices.
The routine gSetCharSizePoint() sets the size of subsequent character/font output in physical points or pixels, without regard to the character mode, any transformation or viewport. The value of points is usually only accurate to the nearest integer value but can be given as a real or integer. On screen devices, the units used are measured in pixels (not true points) and this can be used in conjunction with the routine gSetLineWidthPixel(). If GINO is currently in hardware, software or mixed character mode, a temporary switch is also made to 'point character mode' as if gSetPointChars() had been called, and remains in that state unless a call to gSetCharSize() is made.
The character size setting reverts to current units if the routine gSetCharSize() or any of the character mode setting routines are called.
If points is less than or equal to zero, the current character size is reset to the default character size and a warning message is output.
