This command is a Tcl wrapper of some OpenGL functions. It allows to use OpenGL commands directly from GiD-Tcl.
For example, for C/C++ is used:
...
- doscrzoffset <boolean> Special trick to avoid the lines on surfaces hidden by the surfaces.
- font push pgfont pushfont <font_name font_size>|pop|measure <text>|current|metrics ?-ascent|-descent|-linespace|-fixed?
...
- type>|popfont|print <text>|dimensions <text>|foreground <red> <green> <blue> <alpha>|background <red> <green> <blue> <alpha>
Push sets the current OpenGL font, pop restores the previous one
measure <text> returns the amount of space in pixels to display this <text>
current returns a list with the current font name and size
metrics returns a list with current font metrics information: -ascent -descent and -linespace in pixels, -fixed is 1 if all characters have equal size . These commands push/pop must be always paired
font types: DefaultFont, AxisFont, LegendFont, LabelFont, GraphFont, AsianFont, TkdrawoglFont, PmFont
Example:
