SET_BG_COLOR
The SET_BG_COLOR command sets the color to use for any background pixels when rendering layers. The
following parameters are supported by the command.
• COLOR - specifies the background color to use. The color should be specified as
RGB(,,). For example, to make white the background color, use
COLOR=RGB(255,255,255).
SET_LOG_FILE
The SET_LOG_FILE command sets the name of the file to log status, warning, and error messages to. If the
log file specified already exists, the messages will be appended to the end of it. The following parameters are
supported by the command.
• FILENAME - full path to log file to write messages to
SET_VERT_DISP_OPTS
Global Mapper User's Manual
The SET_VERT_DISP_OPTS command allows you to modify the options used when rendering elevation
layers, such as the shader to use, if any, as well as the lighting and water setup. The following parameters are
supported by this command:
• ENABLE_HILL_SHADING - this setting controls whether or not hill shading (i.e. lighting,
shadowing) will be done. Use YES to enable hill shading, and NO to disable hill shading.
• SHADER_NAME - this sets the name of the shader to use when rendering elevation data. This must
be one of the names displayed in the shader drop down in Global Mapper, such as "Atlas Shader" or
"Global Shader" or the name of a custom shader.
• AMBIENT_LIGHT_LEVEL - this sets the ambient lighting level. The valid range of values is [0.0,
1.0], with smaller numbers meaning completely black (i.e. no light) and 1.0 being full lighting.
• VERT_EXAG - this sets the vertical exaggeration to use when rendering elevation overlays. This
effects the hill shading. The valid range of values is (0.0, 100.0].
• LIGHT_ALTITUDE - this sets the altitude angle of the light source that creates shadows on elevation
data. The valid range of values is [0.0, 90.0], with 0.0 meaning a light source at the horizon and 90.0
meaning a light source directly overhead.
• LIGHT_AZIMUTH - this sets the direction angle of the light source that creates shadows on elevation
data. The valid range of values is [0.0, 360.0), with 0.0 meaning a light source from the top of the
screen (i.e. north), 90.0 meaning from the right (i.e. east), etc.
• SHADE_DARKNESS - this sets the minimum black level that a shadow can create. The valid range
of values is [0,255], with 0 allowing complete blackness from a shadow, and 255 allowing no shadow
at all.
• SHADE_HIGHLIGHT - this sets the level of white highlight applied to terrain areas directly facing
the sun/light angle. The valid range of values is [0,255], with 0 applying no highlight and 255 making
the direct areas always brightened completely to white.
• ENABLE_WATER - this setting controls whether or not water will be displayed on top of elevation
values at or below the currently configured water level. Use YES to enable water display, and NO to
