All that is gold does not glitter.
This is a demo of how you can do a magnifying glass/telescope effect.
I've put some images down the left-hand side to illustrate the process, which is basically as follows.
1. Copy the section of the image you want to magnify.
2. Erase a hole in it.
3. Copy a magnified version of the section.
4. Put the image with a hole in it on top of the zoomed copy.
5. Put the image over the corresponding part of the big map
6. Draw a rim over the top.

I just realised that it would be more efficient to erase the outside of the circle of a zoomed image rather than the inside of the unzoomed one. The
area that needs to be erased is reduced to about a quarter this way. The steps in the process would be fewer too.
1. make a zoomed copy
2. erase the area outside the circle.
3. put it over the map
4. add the rim.

This version lights up the area under focus a bit, but be careful not to set fire to the map.

Thanks Mike,
And treat yourself to a new computer, you deserve it.

Wow, i try it.... When I have the time I would like to implement some of your programs using div dlls if you allow me.

Of course, that would be great. I'd like to do that sort of thing myself but I'm clueless when it comes to the low level stuff. I've got quite a few
ideas for dlls that would enhance DIV. Maybe we could work together on this.
By the way did you manage to burn the map?
Vortigano - 11-3-2019 at 01:18 PM
I tryed it. It looks very good. The map burned from the right side.
