Editing Label (section)

=Settings=
Here are all the label settings and their general effect.  For each label setting, see the respective web page for more details.

'''[[label_angle_digits]]'''
:: sets the number of decimals in angle label.
'''[[label_distance_digits]]'''
:: sets the number of decimals in distance label.
'''[[label_shadow_mode]]'''
:: sets whether or not PyMOL will ray trace shadows for your label text.  Eg: <source lang="python">set label_shadow_mode, 2</source>
'''[[label_color]]'''
:: sets the color of the label text.  Note that you can have labels of different colors for different objects or selections. Some examples:
<source lang="python">
# per-object:
set label_color, color-name, object-name  #eg, set label-color, magenta, /protein

# per-atom:
set label_color, color-name, selection    #eg, set label-color, marine, /protein/A/A/23/CA

# another example
fragment arg
label all, name
set label_color, yellow, arg
set label_color, red, elem c
</source>

'''[[label_font_id]]'''
:: sets the font to render your label.  There are 12 different fonts from 5&mdash;16.  Numbers 15 and 16 are special for unicode.  Eg: <source lang="python">set label_font_id, 12</source>. See the [[label_font_id]] page for explicit examples on how to use unicode characters in PyMOL labels.
'''[[label_size]]'''
:: sets the size of the text.  You can use positive numbers 2, 3, 4, etc for point sizes, or negative numbers for Angstrom-based sizes. Default is 14 points. Labels in Angstrom-size scale with the distance from the front plane, labels in point-size don't.  Eg: <source lang="python">set label_size, -2  #results in a size of 2 Angstroms</source>
'''[[label_digits]]'''
:: sets the number of decimals in label. It affects all digits only if label_distance_digits or label_dihedral_digits or label_angle_digits are set to -1.
'''[[label_outline_color]]'''
:: each label is outlined (so you can do white-on-white labels, for example).  This options sets the color of the label outline.  Eg. <source lang="python">set label_outline_color, orange</source>
'''[[label_dihedral_digits]]'''
:: sets the number of decimals in dihedral label.
'''[[label_position]]'''
:: sets any offset from the original X,Y,Z coordinates for the label.  If you like to use the mouse, you can enter [[edit_mode]] and '''ctrl-left_click''' to drag labels around; '''ctrl-shift-left_click''' will let you move the labels in the z-direction. '''"Save labels"-workaround''' If you want to save the position of your labels, the best way might be to create a new object and move the atoms in this object. Since the labels are positioned from the atom positions this is an indirect way of moving the labels and being able to save them.
