Greetings,
I've been playing around with displaying
text to a window using text objects.
The problem is that it is way too slow!!
(as an example)
I have a line of text that is made of 3 strings.
So I create a textobject, arranging the 3 strings
horizontally.(using /onglass)
I have 28 "lines" of text, so I make 28 text objects.
Now I want to display the text to screen (outwindow).
So I call a method that loops through the
text objects, and adds each object to a model.
(one model, with 28 text objects)
I then add the model to my view, and
draw the view (outview).
The command:
IDL> outwindow->Draw, outview
takes 3.7 seconds on my comp (winNT 400 mhz pc).
This is way too slow. Why does it take so long to
draw a screen of text??
I am playing around with making one text object,
made with a string array of 3 (columns) by 28 lines,
but I want to change font and colour of the individual
line based on user input.
How do you write textobjects quickly to the screen in IDL?
TIA
Cheers,
bob
