Memory Map

Can you copy and paste parts of a map into a bmp or jpeg?

As Dean says, I think print-screens are the only option. Certainly,
in the version I've got there's no "export" option. Probably the OS's
crappy licensing scheme again.

A decent screengrabbing program like Hypersnap is better, you can set it
to grab precise tile areas to make for easy stitching later.

Screengrabbing is one way, but you are limited to the resolution of
your monitor/video card. If you want an image of a sizeable area, to
get decent quality you have to zoom in and hence capture only a small
area at a time, which in turn means more pieces to glue together.

A good alternative is a Virtual Printer with imaging capability. This
sits logically between MMN and your real printer. When you print, it
intercepts the print request and presents you with a raft of options,
one of which is to save as an image file. The important thing is that
the saved image is at high resolution, regardless of what you see on
the screen. So in MMN, you can zoom out to frame a large map area in
the window, and the details are so small you can barely see them if at
all, but the image file will be at high resolution, and you can just
use your Graphics App to select the exact area you want at high
quality, with no gluing of pieces involved.

Yes, just set the MM magnification accordingly and use a screen-dump
utility to capture a number of screens; then use a photo-stitch utility
to glue them together.

However, what would you do with the resulting image? If it's a modern OS
map, then the OS still retains copyright on the contents of the final
image -- do they not?

Actually it wouldn't matter if the maps were > 50 years old, the fact
that they've been digitized means that they are new works and therefore
protected by copyright for another 50 years. But it might mean that the
new owners were less restrictive in their usage licences.

Yes but I have a licence to use them on any non-commercial site. See them at

AIUI this is only true if the digitisation process required a
substantial art in its own right.

You're kidding.

I've found the best way, is to generate a screen grab, then paste to
'Paint' and immediately save as a bitmap.

I then use ACDSee to edit and crop the map, then save and finally
convert to either a GIF or JPEG.

The size and resolution can be adjusted in ACDSee.

Hope this might be useful to you.

Purchasing a complete series of 50 year old paper maps and digitizing
and calibrating them in order to make a single seamless map would be a
substantial investment of someones time and money and therefore would
deserve protection.

Is this so? Does the video card make a difference?

The higher the screen res, the larger the area you can grab at one time.
I use at least 1280x1024. 1600x1200 would be better if you can see it
clearly enough.

I assumed that if
you grabbed the image (zoomed to 100%) with printscreen and save this
as a .bmp then each pixel in the image corresponded to each pixel in
the saved file??

Yes.

Yes.

If you use a program like Hypersnap, you can specify the area to grab
(using the zoom window and pixel readout to position the cursor
accurately) then use the repeat grab function to grab exactly the same
area. Thus you start by defining exact grid squares, then grab, scroll
the map, grab again, scroll the map and so on. Provided the program
scrolls in grid square increments each grab is easy, you never have to
fiddle with the positioning again.

The other part of the equation is piecing the grabs together. With
Photoshop this is easy, you just set up a grid with 200 or 400 pixel
squares (50k or 25k) and set it to "snap to grid". Hypersnap can be set
up to grab directly to the clipboard, so after grabbing it's ready for
instant pasting into Photoshop, which can be done quickly because the
pieces just snap into place.

So the you simply grab, paste into the grid, scroll the map, grab again
and so on. It takes a little while, but so long as you set up the first
grab accurately it all fits together perfectly.

I have looked at the memory map and screen grabbed images, it looks to
me that at the highest magnification there is some sort of
extrapolation.

You've zoomed in too far. You can tell the correct size, it "looks"
right. Just check the size of each grid square to be sure, 200 pixels
wide for 50k squares, 400 wide for 25k.

For this purpose it hardly matters whether you can see it clearly,
other than to ascertain you have the right area,

Exactly, that's what you need to see it clearly for, to set the
screengrab area precisely.
