I am currently programming in sunview(sunwindows) for a class project. I
created a canvas window of size 1100(height), 700(width) with
CANVAS_AUTO_SHRINK set to FALSE to edit & view a canvas of size 2500, 1100
(width, height). I am drawing onto the canvas using the canvas' pixwin.
I want to SAVE my drawing on the CANVAS into a FILE(People familiar with
'fig' may know that it is similar). I used pw_read to read the flowchart
into a pixrect and then used pr_dump_image to dump the pixrect into a
file. It did not work. I tried many variations but could not get it to
save.
I went thro' the sunview system's programmer's manual also and did not
find a way to do it (I don't know if I missed any info' :-)).
Also I want to LOAD the drawing from the FILE onto the CANVAS.
If Anyone has worked on this particular aspect in sunview, please send me
your suggestions/methods to do it(save canvas onto a file & load onto the
canvas from a file) and save this soul!!
PLEASE mail your suggestions to me at the earliest possible.
Thanx in advance,
