Scaling to pivot point

[Buro LST]

Our company works with complex drawings and sometimes we need to place 2 drawings onto each other. most of the time they have different scales.

The fastest way for us to scale those drawings is to pick one point and match those and then scale the image to that point.

In PSP u can move the pivot point to rotate around it but i haven't found how to scale toward that point.
In photoshop u just hold the "Alt" button when scaling and it scales around the pivot point. That is what i want.

I've contacted the official help but they could not help me (they don't explain the working of their program )

I've attached a image that explains what we try to do. The above is what happens in PSP and the lower part is what we want to happen.
As is visible in the upper images the cross moves out of the pivot point while in the lower part the cross stays in place.

Hopefully this is a bit clear and somebody knows an anwer.

If you're using a raster drawing I don't believe there is a built-in way to do that. PIck tool can't do that.

Offhand, I think it might be possible to fake it using scripts. You'd have to use a custom dialog with a scale factor instead of dragging. But you might be able to make that work. I'm not familiar with all of the math behind it but I think it could work.

Vectors, however, can scale around the exact center of the object by using a vector tool in edit mode and holding CTRL as you scale. You can't move the center point to another location. But it can scale all four points at once.

Just checked and a possible scaling might be to use a selection positioned where you want the resized image and then do a copy of the other image and paste into selection.

Thanks for the replies.

We almost always get raster images and i don't think i'll be scripting much.

I've tried hartpaul's suggestion and it gets close but is a bit of work.
The best way i can think of for now is choosing a point as close to a corner as possible and then scaling toward that corner.
