[news.eclipse.tools] Re: GC.drawImage()

[Thomas Mäder <thomas_maeder@xxxxxxx>]

I'm not an SWT hacker, but you could try this:

1) use GC.copy(int, int, int, int, int, int, int, int) to copy the area of the
image that is still visible in the new scroll position
2) only draw the part of the image that has become newly visible because of
the scrolling.

but perhaps an SWT guy has a better way?
