Global Mapper User's Manual
should be specified in the current global projection. For example, if you have a UTM/meters
projection active and want to expand the bounds retrieved from the LAYER_BOUNDS parameter by
100 meters on the left and right, and 50 meters on the top and bottom, you could use
LAYER_BOUNDS_EXPAND="100.0,50.0". You can also specify a single value to apply to all 4
sides, or supply 4 separate values in the order left,top,right,bottom.
• ANTI_ALIAS - specifies whether to remove jagged edges by making a subtle transition between
pixels. Turning off this option helps maintain the hard edges of the pixels as they are rasterized. Use
ANTI_ALIAS=YES to turn on. Anything else turns it off.
• CONTRAST_MODE (raster only) - specifies the type of contrast adjustment to apply to the data.
♦ NONE - no contrast adjustment applied (this is the default)
♦ PERCENTAGE - apply a percentage contrast adjustment. The
CONTRAST_STRETCH_SIZE parameter can be used to override the number of standard
deviations from the mean to stretch to.
♦ MIN_MAX - apply a min/max contrast stretch, stretching the available range of values in
each color band to the full range of 0-255. For imagery which contains both black and white,
this will have no affect.
• CONTRAST_SHARED (raster only) - specified whether or not the contrast adjustment for this layer
will share the adjustment with other contrast-adjusted layers in order to ensure a consistent
modification across layers. Use CONTRAST_SHARED=YES to enable contrast sharing.
• CONTRAST_STRETCH_SIZE (raster only) - specifies the number of standard deviations from the
mean to use in a PERCENTAGE contrast adjustment. The default is 2.0.
• AUTO_CONTRAST (raster only) - DEPRECATED, use CONTRAST_MODE instead - specifies
whether to automatically calculate and apply a 2 standard deviation contrast adjustment to the image.
Use AUTO_CONTRAST=YES to turn on. Anything else turns it off.
• COLOR_INTENSITY (elevation and raster only) - specifies the color intensity to use when adjusting
the brightness of pixels in the overlay. Valid values range from 0 to 20, with 0 being completely
black, 10 being no alteration, and 20 being completely white. For example, to make an image slightly
darker, you could use COLOR_INTENSITY=7. (NOTE: This parameter has been deprecated in favor
of the COLOR_INTENSITY_FULL parameter).
• COLOR_INTENSITY_FULL (elevation and raster only) - specifies the color intensity to use when
adjusting the brightness of pixels in the overlay. Valid values range from 0 to 512, with 0 being
completely white, 256 being no alteration, and 512 being completely black. For example, to make an
image slightly darker, you could use COLOR_INTENSITY=300. (NOTE: This parameter replaces
the COLOR_INTENSITY parameter).
• TEXTURE_MAP - specifies that this image should be draped over any elevation data loaded before
it. Use TEXTURE_MAP=YES to turn on. Anything else turns it off.
• TRANSPARENT_COLOR - specifies the color to make transparent when rendering this overlay. The
color should be specified as RGB(,,). For example, to make white the
transparent color, use TRANSPARENT_COLOR=RGB(255,255,255). If you do not wish any color
to be transparent, do not use this parameter.
• TRANSLUCENCY - specifies the level of translucency (i.e. how "see-through" the layer is). Value
values range from 0 to 512, with 0 meaning the layer is completely transparent (i.e. invisible) and 512
meaning the layer is completely opaque (this is the default).
• BLEND_MODE - specifies the blend mode to use for combining this overlay and any previously
loaded overlays
♦ NO_BLEND - no blending is done, this is the default
♦ MULTIPLE
♦ SCREEN
♦ OVERLAY
♦ HARD_LIGHT
♦ COLOR_BURN
