You can set default values for all of the HSV and RGB
modification controls in the x v color editor window via X
resources. The easiest way to explain this is with an example.
- Start xv and put it in the background by typing 'xv
&'.
- Type the command 'cat >foo' in an active xterm
window
- Bring the xv color editor window up.
- Issue the Cut Resources command.
- Click your middle mouse button in the xterm
window. A set of resource lines describing the current
state of the xv color editor controls will be
'pasted' into the window.
- You could type <ctrl-D> in the xterm
to complete the cat command, edit this file, and
put it in your .Xdefaults or .Xresources
file.
The lines generated by Cut Resources will look like this:
xv.default.huemap1: 330 30 CW 330 30 CW
xv.default.huemap2: 30 90 CW 30 90 CW
xv.default.huemap3: 90 150 CW 90 150 CW
xv.default.huemap4: 150 210 CW 150 210 CW
xv.default.huemap5: 210 270 CW 210 270 CW
xv.default.huemap6: 270 330 CW 270 330 CW
xv.default.whtmap: 0 0 1
xv.default.satval: 0
xv.default.igraf: S 4 : 0,0 : 64,64 : 192,192 : 254,254
xv.default.rgraf: S 4 : 0,0 : 64,64 : 192,192 : 254,254
xv.default.ggraf: S 4 : 0,0 : 64,64 : 192,192 : 254,254
xv.default.bgraf: S 4 : 0,0 : 64,64 : 192,192 : 254,254
These lines completely describe one state of the xv color
editor controls. There are five different states that you can
specify via X resources. The 'default' state (as shown)
holds the settings used whenever the program is first started,
and whenever the Reset command is used. You can also store
settings in one of the four xv presets (accessed via the 1,
2, 3, or 4 buttons in the xv color editor) by
changing the string 'default' in the above lines to 'preset1',
'preset2', 'preset3', or 'preset4'
respectively.
There are four types of resource described in these lines: huemap
, whtmap , satval , and graf .
The huemap resources describe the state of the hue
remapping dials. There are six huemap resources per state of the xv
color editor. These huemap resources are numbered 'huemap1',
through 'huemap6', and correspond to the '1'-'6'
radio buttons under the hue remapping dials.
Each huemap resources takes six parameters:
- The 'starting' angle of the From range, in degrees
(integer).
- The 'ending' angle of the From range, in degrees
(integer).
- The direction of the From range. Either 'cw'
(clockwise) or 'ccw' (counter-clockwise).
- The 'starting' angle of the To range, in degrees
(integer).
- The 'ending' angle of the To range, in degrees
(integer).
- The direction of the To range. Either 'cw'
or 'ccw'.
The whtmap resource describes the state of the white
remapping control. There is one whtmap resource per state of the xv
color editor controls. The whtmap resource takes three
parameters:
- The hue to remap 'white' to, in degrees (integer).
- The saturation to give to the remapped 'white', in
percent (integer).
- A boolean specifying whether the white remapping control
is enabled. If '1', the control is enabled. If '0', the
control is disabled.
The satval resource describes the value of the
Saturation dial. There is one satval resource per state. The
satval resource takes a single integer value, in the range 100,
which specifies how much to add or subtract to the overall image
color saturation.
The graf resources describe the state of the four
'graph' windows in the xv color editor window ( Intensity,
Red, Green, and Blue). The graf resources
can be in one of two formats, 'gamma' and 'spline/line'.
In 'gamma' format, the graf resource takes two parameters:
- The letter 'G', specifying 'gamma' mode
- A single floating point number specifying the gamma
value.
In 'spline/line' mode, the graf resource takes a variable
number of parameters:
- The letter 'S' specifying 'spline' mode, or the letter
'L' specifying 'line' mode.
- An integer number indicating the number of handles
(control points) that this graph window will have. (Must
be in the range 2-16, inclusive.)
- For each handle, there will be a ':', and the x
and y positions of the handle, separated by a
comma. The x and y positions can be in the
range 0-255 inclusive.
- autoApply
- A boolean resource that sets the default condition of the
Auto-Apply HSV/RGB Mods checkbox in the xv
color editor window.
-
- displayMods
- A boolean resource that sets the default condition of the
Display With HSV/RGB Mods checkbox in the xv
color editor window.
-
- dragApply
- A boolean resource that sets the default condition of the
Auto-Apply While Dragging checkbox in the xv
color editor window.
-
- autoReset
- A boolean resource that sets the default condition of the
Auto-Reset On New Image checkbox in the xv
color editor window.
-
- saveNormal
- A boolean resource that sets the default condition of Normal
Size checkbox in the xv save window.
-
- pspreview
- A boolean resource that sets the default condition of Preview
checkbox in the xv postscript window.
-
- pscompress
- A boolean resource that sets the default condition of Compress
checkbox in the xv postscript window.
-
- print
- A string resource that sets the default command that
shows up in the Print dialog box.
-
- pspaper
- A string resource that sets the default paper size
selected in the xv postscript window. Valid
settings are: 8.5x11, 8.5x14, 11x17, 4x5 35mm a3 a4
b5
-
- psorient
- A string resource that sets the default image orientation
in the xv postscript window. Valid settings are: portrait
and landscape
-
- psres
- An integer resource that sets the default image
resolution in the xv postscript window. Valid
settings are in the range 10 through 720 dpi.
Window Classes
xv defines the following 'class' names for its various
top-level windows:
- XVroot
- for the xv image window
-
- XVcontrols
- for the xv controls window
-
- XVdir
- for the xv load and xv save windows
- XVinfo
- for the xv info window
- XVcedit
- for the xv color editor window
- XVps
- for the xv postscript window
- XVjpeg
- for the xv jpeg window
- XVtiff
- for the xv tiff window
- XVconfirm
- for all the pop-up windows
You may be able to use these class names to do something nifty
with your window manager. For instance, with mwm you can
control which controls you'll get in the window frame, on a
per-window basis. For example, to turn off all the mwm
doodads that normally are tacked onto the xv image window,
you could put this in your .Xdefaults file:
Mwm*XVroot*clientDecoration: none
