Cartographer: PaintShop Pro: to convert color bitmap into grayscale

Thanks to Donald McLennan for this section

1st method:

Edit the file containing your map in PaintShop Pro:
Transform a color map into a 16 colors (4 bits depth) or 2 colors (1 bit depth) bit map as you wish - select the menu Color Gray Scale. Then,

• Select the menu Color Decrease color depth 16 colors (4 bits) for gray scale bit maps (Palm III or equivalent only)
  or,
• Select the menu Color Decrease color depth 2 colors (1 bit)" for black and white bit maps.

In the dialog window, choose the option Palette Windows.
Save the picture - use the File Save As... option and choose the Windows Bit map (.bmp) format.

2nd method

When importing the map image from the clipboard, the image resolution will be set to your current Windows desktop configuration. PaintShop Pro or other graphics utilities provide powerful tools to convert these high resolution, multiple colors to the black and white or greyscale images supported by the Pilot. We’ve found that a 2 step reduction allows us to maintain the proper level of information. Depending on the mapping software, the colors for streets, highways, etc., are red, gray, blue, black, etc. When reducing the colors, it is likely that the red and blue values will be converted to white. We recommend the following procedure:

• First reduce the image colors to 16. This reduces the color palette to a manageable set of colors. From the PaintShop Pro Menu, Colors Decrease Color Depth to 16.
• Once the number of colors have been reduced to 16, then it is often necessary to convert the gray, light blue, white or red color values to black. To do this, edit the color palette. From the Paintshop Pro menu, Colors, Edit Palette.
  Double clicking the selected color, allows you to change the image color. We’ve found that changing the grays, light blues, and red values to black provides an excellent quality map image.
• Once the colors have been converted to mostly black and white, then simply reduce the image colors to 2. From the PaintShop Pro Menu, Colors, Decrease Color Depth to 2.
