Editing Tgif (program) (section)

==Quirks ==
Because Tgif was developed long before a standard way for drawing programs to work, one might find it unfamiliar to use in a number of ways:
*Although Tgif mention point sizes, it uses a unit that is 1/128 of an inch for point sizes. 
*While there is an option to display font sizes in points, the sizes are still subject to rounding to the nearest 1/128".
*Unlike modern drawing programs, Tgif uses [[spline curve]]s instead of [[Bézier curve]]s.
*Also unlike modern drawing programs, Tgif does not allow the user to select a colour from a color wheel or through controls that allow the user to adjust colour values. Instead, Tgif provides a list with a short list of colours. If the user wishes to use a colour that is not in the list, they would need to add their desired colour to the list. This list is then saved with the currently-open drawing.
*Usable fonts are listed in a configuration file. If the user wishes to use fonts that are not on the list, they would have to change the configuration file.
*Only fonts in the [[ISO 8859-1]] encoding (i.e. "square") [[CJK]] fonts and [[Symbol (typeface)|symbols]] or [[dingbat]] fonts can be used.
*Rescaling can lead to ugly defect, which is most likely due to both the use of integer coordinates and roundoff errors.
*Because Tgif uses Xlib (which predated modern [[Unicode]] support) Tgif does not and cannot support Unicode.
