Map-Printing Program

Simple program to print 2x1 maps, with a border for printer error. Choose printer from folder, inkjet printing works well because mosaics of maps align well when printed with them. Select map and press print. Do next in the list. The picture here shows a section of a 1:50,000 scale map that will print well, though if the same map were reduced to 4 by 8 squares or 3 by 6, the quality would be better. This picture does not show the high quality of the same one printed. 

You first need to acquire maps that have widths double that of their height - screen snips from your own program and trimmed with simple photo software.

The result can be a large area of a wall covered with the most fascinating wallpaper. You may spend a long time pondering, getting to know your locality and countryside for example.

Some printers may need setting on landscape as default, in case they don't accept commands from this program. printing

GPS Mapping for Laptop

Uses a USB GPS module. Use maps, aerial views or sketches, calibrate and watch dot move around on screen. This is quite hard to use, needs simplifying. Will use a GPS module made for it if upgraded, though a fully portable one would be better, using bitmaps and a graphical LCD. The GPS Recorder mapping is better than this one.

Please contact for info. The GPS Recorder is a better system and uses a separate program. For easiest mapping, download your GPX files to Google Earth or mapping from other firms/systems.

Video Stills Position

Place program in same folder as video files (avi, mpg, mpeg), use the program to more accurately position the video for grabbing screen snips than when pausing standard media players. Because the video window is large the resolution of your screen snips is good, whereas when using video editing software, the preview panes are usually small. The program needs Windows Snipping Tool (C:\Windows\System32\SnippingTool.exe), or alternatively you can create your snips with the standard PrintScreen command on PC keyboards.
