NAME
xcoloredit - find colour values by graphical colour mixing
SYNOPSIS
xcoloredit [ standard X Toolkit arguments ] [ -silent ] [ -format
"format string" ] [ -text "example text" ][ {0-255} .. ]
DESCRIPTION
xcoloredit provides a graphical method of mixing the three primary
colors 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
decrements 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
corresponding 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
foreground and background colours. The example text can be modified
using the -text command line option.
