Wireless bitmap (WBMP)

A WBMP image can be used in& WAP pages to display charts on the wireless devices. Currently, there is only one type of WMBP specified by the Wireless Application Environment Specification. This format supports only monochrome images.

 

When WebCharts3D produces a WBMP image it automatically substitutes colors with black and white patterns in the following way:
  1. Every color is split into red, green and blue components. If the value of the component is more than 128, the component color is selected, otherwise it is ignored.
  2. The eight possible combinations of the component colors are mapped into eight distinct patterns (including empty pattern for the white and filled pattern for the black colors).

The wireless devices' screens are usually small. When you display the WBMP images, you might want to select small fonts, turn the axis labeling off and/or use ratio parameter to scale the image. The image in this page shows a 300x200 pixel chart scaled by 50%.

WebCharts 3D Design-Time Control does not support WBMP images. To develop pages that contain these images you need to use either Standard Components or Image Server/Components API.
