SYNOPSISxcoloredit [ standard X Toolkit arguments ] [ -silent ] [ -format "for‐
mat string" ] [ -text "example text" ][ {0-255} .. ]
DESCRIPTIONxcoloredit provides a graphical method of mixing the three primary col‐
ors available on a colour workstation. This mixing can be done using
the Red, Green and Blue slider controls on the left of the window or
using the Hue, Saturation and Value slider controls on the right.
The three boxes above the Red, Green and Blue slider controls are used
for linking the controls together via the fourth slider to the right of
the blue slider. Whilst in the slider controls the first mouse button
increments the colour components value, the third mouse button decre‐
ments the value (this only works with the Red, Green, Blue and Linked
sliders). The middle mouse button allows the user to continually
change the value.
The results of the colour mixing is shown in the four central squares.
The three smaller squares showing the intensities of the red, green and
blue components. The hexidecimal value below these squares is the cor‐
responding colour value which can be used in defaults files. This
value is also placed in the PRIMARY_COLOR selection property. If the
user presses the colour value button the button is highlighted and the
colour value is placed in PRIMARY_SELECTION as well (useful for pasting
into defaults files).
At the bottom of the main window are 36 colour cells. The current
colour cell is highlighted by box drawn around it. By clicking with
the first mouse button in another cell this new cell's current value
can be edited (if the cell has no defined value the current cells value
is copied to it and the cell is highlighted with a dashed box). These
colour cells can be connected to cells in the default colourmap of the
display. To do this the user must give the colourmap entry number(s)
(pixel number) as a command line argument(s).
The text shown in the mixed colour window can be displayed in one of
the 36 colour cell colours. Typing "c" or "t" in this window changes
the colour of the text to that of the currently selected colour cell.
This can be used to see what text will look like with different fore‐
ground and background colours. The example text can be modified using
the -text command line option.
OPTIONS
Apart from standard X Toolkit options, the following are available:
-silent
Do not print out the edited colour values when xcoloredit quits.
-text "example text"
This sets the example text to display in the mixed colour win‐
dow. Newlines are allowed in this string.
-format "format string"
This string is the format used to display the RGB value of the
colour. This format is used by the printf(2) function call. By
default the format is set to "#%02x%02x%02x" which is the stan‐
dard RGB format for X.
SELECTION ATOMS
The following selection atoms are used/defined:
PRIMARY_COLOR - current colour selection value
PRIMARY_SELECTION - current colour selection value when highlighted.
