Map Backgrounds
One of the features of the NEM Network Browser is the ability to display background images for the network maps. The backgrounds might be a map of a country, region or city, or possibly of a building, etc.
There are a number of ways to generate your own backgrounds:
• use a scanner to scan some images.
• search the Internet for suitable maps.
• create your own backgrounds using a graphics tool.
Do not forget that most books and maps are protected by copyright.
Color images generally look better and can display more information, but note the following:
• Do not choose an image with too many bright colors, as you will not be able to see the NEs easily.
• Multi-color images use more file space and memory and so they are slower when they are being loaded. For each pixel there are 4 - 64 bits to describe the colors as opposed to 1 bit to describe the colors for a (black and white) bitmap.
• You may experience problems with images which have large numbers of different colors. Many workstations can only display a limited number of colors simultaneously, with a result that the backgrounds might not be displayed properly. In practice this often depends on which other applications are running on the workstation.
Please note:
The files must be in JPEG format. The only limit for image size is 120M pixels (120,000,000). This means “width-in-pixel” multiplied by “height-in-pixel” must not exceed this number. The file size and the DPI don’t matter.
