How to view large images
Viewing large images can be quite tricky. Maps and other outputs of OpenStreetMap tools can sometimes be in the form of really large images. You could try to look at the whole picture and pan and zoom in the various picture viewers, but this can require a lot of memory and may be quite slow.
Slice up the image
One workaround is to slice the picture into pieces and start a slide show and lean back.
Here is one way to do this:
- create an empty folder
- copy big file here
- use imagemagick's convert to convert to jpg format
- use imagemagick's convert -crop to slice the picture
- now select the first picture and start the slide show
Installation for Ubuntu
sudo apt-get install imagemagick
Convert image format
convert file.png file.jpg
convert file.jpg -crop '1024x768' out.jpg
