Hello all!

I'm pretty sure I've seen this haggled over in the fourms before, but I'm not sure that I've seen a solution.

In my application I draw a listbox using lines, boxes, and then text. As the list grows, however, it takes longer to process, and slows the program down a bit.

In an attempt to optimize this, I wrote the code so it would use GET IMAGE to take a "snapshot" of the listbox. If the user hasn't scrolled or clicked on an item, I simply show the snapshot. If there is user interaction, I actually draw all items again, then take another snapshot.

This works good and well, but the snapshot image looks terrible!!! Fuzzy!!
Does anyone know what can be done about this? I have tried two different computers with 2 different video cards.

Thanks!

get image #,x,y,x2,y2,1

The bit in the bold is the key bit.

Cheers,

Rich

Thanks Rich. This solved the blurry prob... The GET IMAGE seem to have slowed it down, however... Interesting... I'll have to experiment more.

when you load the imge type

load image "imagename",1,1

again the bit in bold is important
also remember not to use jpg files ( they are quite crappy ) i would say bitmap images are the sharpest

I have a word of advice...
..don't piss on an electric fence!

Now we are talking about it... What is the last bit for? Why isn't it on as default?
