Colorbar
The Colorbar
plugin shows a colorbar indicating the colormap applied
to the image and showing the example values along the range.
Plugin Type: Global
Colorbar
is a global plugin. Only one instance can be opened.
Usage
Clicking and dragging in the Colorbar
window will shift the colormap
left or right. Scrolling will stretch or shrink the colormap at the
cursor position. Right-clicking will restore the colormap from any
shift or stretch.
If the focus shifts to another channel, the colorbar will be updated to reflect that channel’s colormap and value information.
It is customizable using ~/.ginga/plugin_Colorbar.cfg
, where ~
is your HOME directory:
#
# Colorbar plugin preferences file
#
# Place this in file under ~/.ginga with the name "plugin_Colorbar.cfg"
# Set colorbar height, if default is too big or little
cbar_height = 36
# size of font used in the color bar
fontsize = 10
