899.0. "Non-Horizontal Text" by TEACH::ART (Think the UNTHINKABLE) Wed Jun 07 1989 15:10

	Am I missing something obvious, or is there no built in way
	to write a a text string that is rotated away from the horizontal 
	in DECW ?  Other windowing systems provide some way to specify an 
	angular offset for text.

	It seems to me that, if I want a string of characters
	going up the side of a graph (for instance), I actually have
	to use a font that's already rotated.  Is that the case ?
	If not, what am I missing ?

	Thanks,

899.1	A limitation of the X drawing model	SDSVAX::SWEENEY	Gotham City's Software Consultant	`Wed Jun 07 1989 15:18`	6
	This is a limitation of the X drawing model. Potentially a font could be composed of rotated text, but that would need to be specially done. The general solution to this will be Display Postscript, quo vide the note I wrote earlier today.
899.2	not with vanilla X	NEURON::NICHOLSON	A belly as big as an oil spill	`Wed Jun 07 1989 15:21`	9
	X gives you basic functionality (all the flash will come from extensions) so you can't rotate text (or rectancles or elipses) with it. I've assumed that the display post-script extension will do rotating text, but I'm not sure. Mark
899.3	How DECterm (slowly) rotates ReGIS text	HANNAH::MESSENGER	Bob Messenger	`Wed Jun 07 1989 17:48`	11
	DECterm draws rotated text by writing each character to a pixmap, calling XGetImage to read the bitmap pattern, rotating the pattern in memory, and then drawing the rotated character with XPutImage. This is on monochrome systems; on color systems it's even worse, because it has to draw the (single plane) pattern to a pixmap and then use that pixmap as a stipple pattern to draw in the main window. A server extension would speed this up quite a bit... -- Bob

	Gee, I seem to remember this conversation 2� years ago...
899.5	DPS will, uh, would do it all right	DECWIN::FISHER	Burns Fisher 381-1466, ZKO3-4/W23	`Thu Jun 08 1989 12:49`	4
	If we had Display Postscript, that would definitely rotate text :-) Burns
