I just tried ximtool with the new 256 color mode and it does not work
properly. Ximtool is a display tool for astronomy which operates only in
256 color mode. Normally when you put your mouse within the window the
color map gets switched to 256 greys, when you go out of the window the
colors get remapped to the color mode used by the active window. With the
latest release of X11 the color map will not switch when you activate the
ximtool window. It will switch if you use the mouse to draw a cursor on the
image, then the redrawn area within the cursor will have the correct color
map. But it will not automatically switch when the mouse enters the window.
There is another feature of ximtool which also does not work and is probably
related. When the cursor is within the image area and you press on the
right mouse button and move the mouse the color map is supposed to update in
real time changing the greyscale mapping (it adjusts the contrast and
display range). The right mouse button does get sent to the program because
other right mouse button functions work as expected but the remapping of the
colors does not function.
Jeremy, I apologize for not testing this during the rc phase but I was using
X11 for some critical work and I did not want to take the chance of breaking
anything. This is not a critical issue for me because I have migrated to
ds9 for most display tasks but I would like to see ximtool work once again
if possible (it has not worked since the old tiger 256 color mode was
nixed).
