Bitmap navigating - preview window for large images
Posted on 2003-12-08
I have a large bitmap which is placed on image in a scrroll box.
I want to have another, small image with scaled down version of the same bitmap, which will allow me to select area to be displayed in the large bitmap.
The small bitmap should have a rectangle which will represent the area displayed in the large bitmap.
Draging this rectangle within the small bitmap will result in scrolling into view corresponding area of the large bitmap.
I'm sure someone has done it already but I can't find it anywhere.
I need working example or a link to working example.
