A customer wants to build his own GKS/PHIGS-like product. He explained
to me that all he needs to know is how to do the following under
DECWINDOWS:
1) Clear screen
2) Draw line
3) Fill Polygon
4) Define Colors
5) Write/read pixel/raster info
I would expect that this kind of info is in the documentation (which he
has) but he hasn't found what he is looking for. Can someone point me
in the right direction.
Thanks

| 2273.1 | doesn't sound like he's actually READ any of the documentation..... | PSW::WINALSKI | Careful with that VAX, Eugene | Wed Feb 14 1990 14:41 | 18 |
For VMS, it's in the Xlib Routines Reference Manual, volume 2A of the DECwindows Programming documentation set. Other sources of this information are the Guides to Xlib Programming for MIT C bindings and VAX bindings. See also books on Xlib programming such as Scheifler, Gettys, and Neumann. Places to start looking: clear screen: XClearWindow draw line: XDrawLine, XDrawLines fill polygon: XFillPolygon define colors: XAllocClor, etc., and the graphics context routines write/read pixel/raster info: XGetPixel, XPutPixel, XGetImage, XPutImage I found the above info in a table at the front of chapter 6 of the Xlib Routines Reference Manual. The chapter is titled "Graphics Routines." --PSW | |||||
