CEDIT(6D)							     CEDIT(6D)

NAME    [Toc]    [Back]

     cedit - edit colors on the	screen

SYNOPSIS    [Toc]    [Back]


DESCRIPTION    [Toc]    [Back]

     The frame buffer of the IRIS contains values which	are translated into
     RGB values	by a color map for applications	in color map mode.  Cedit
     changes the mapping of any	color index.  Three sliders are	displayed,
     along with	a sample patch of the color being edited. Normal operation is
     to	establish input	focus by placing the cursor within the cedit window
     then press	and hold the Alt key down.  While continuing to	hold the Alt
     key down move the cursor outside of  the cedit window and click the left
     button to pick up a color index to	be edited. The sliders indicate	the
     red, green, and blue components of	the current color. Once	the color map
     index has been picked, release the	Alt key	and return to the cedit	window.
  The color can then be changed by clicking down on a slider in
     cedit, and	adjusting the position of the control. Under each slider control
 is a number representing the current value of	that color component.
     The number	ranges from 0 (for least intensity) to 255 (for	most intensity).
  Under the color patch is a number that represents the current color
     index.  The user can toggle between decimal and hexidecimal representations
 of the current RGB values being displayed via the menu item "toggle

NOTES    [Toc]    [Back]

     It	is not possible	for cedit to know if the window	you are	selecting a
     color from	is single or double buffered. This can be a problem on
     machines that have	only 8 bitplanes. cedit	can be made to interpret data
     as	single or double buffered via the last item in the menu. This menu
     will toggle between choices. The menu shows up on 8 bit machines only,
     since it is not a problem on other	machines.

BUGS    [Toc]    [Back]

     If	another	process	changes	the color entry	being edited, the sliders of
     cedit do not indicate the correct positions for that color	index.

     This program must have input focus	in order to work properly.  See	the
     window manager documentation for a	discussion of input focus.

     cedit only	knows about the	frontbuffer. If	the queried pixel belongs to a
     double buffered window, it	is possible for	cedit to grab from the wrong
     buffer. When the window swaps buffers, cedit will be able to grab the
     correct color.

     Some applications use dithered colors so the index	and color of adjacent
     pixels will be different for some regions of the screen.

     Systems with multiple color maps are confusing. Cedit can only edit the
     color map currently installed in the hardware colormap.  Applications
     with their	own color maps cannot be edited	unless their colormap is
     currently installed.
