This actually is the best way to do it, because you can use the image
to write it e.g. to file
There is one thing though which I don't understand.
I adjusted my script the way you described and it works fine.
Like:
data2 = Options(data2,"rendering mode","hardware");
data2 = Options(data2,"line width",2);
data2 = Options(data2,"antialias","lines");
and then
where2 = Display(data2,camera);
image2 = ReadImageWindow(where2);
However, I wanted to add a Caption by adding before the Display command
the following
caption = Caption("Fat line");
data2 = Collect(data2,caption);
This give a error message in the ReadImageWindow module:
0: WARNING: 51::/ReadImageWindow:0 internal error: module return value was
not ERROR
0: ERROR: 51::/ReadImageWindow:0: Internal error: X Error: BadValue (integer
parameter out of range for operation)
0: ERROR: 54::/Display:0: Error code not set:
Isn't it allowed to add captions in the hardware rendering mode ?
Finally, another small question
Is it possible to create dashed or dotted lines in DX ?
ThanksB
Eelco
PS: I added the adjusted script that produces the error messege to the mail
The error is produced when the
data2 = Collect(data2,caption2);
line is un-commented.
When I want to add Caption, however, I get the following error
