:wc: relfile 00-WikiIndex ---3 Xannotate, a desktop annotation tool I like [[http://www.home.unix-ag.org/simon/gromit/] gromit]. It is a tool to do desktop/screen annotation - you can draw on your screen as if it is a big canvas. It is useful to direct attention when you're doing presentation - instead of waving your mouse, just draw a big circle on the items you want to talk about. Well at least, I like the idea. Because it is not working from me, and as much as I tried, I can't get it to work correctly. The code itself is good; the problem is probably the change in the underlying GDK/GTK that it depends on. So I decide to write one myself; this time it depends only on Xlib (the basic X11 library). Picture is worth a thousand words, so here is a screenshot: %center= (m# /wiki/main/images/xannotate00001.png #) %= ---* Features: - Three pens with different colour to use. - Comes with an eraser (and bulk clear command) - You can show or hide your annotation - You can capture a screenshot with or without your annotation. - If you use a compositing manager (kwin, xcompmgr, compton), use the "-a" switch to make it run faster. . Interested? Get is from [[/wiki/main/files/xannotate-2016-10-21.tar.bz2] here]. The package also contains [[./Xscreenshot] Xscreenshot]. ---4 From the README: %wikiseq= To use xannotate, just launch it. It is controlled by a hotkey. This hotkey, along with shifted versions of it, control various aspects of xannotate. By default, this hotkey is the "Pause" key. ---* Keys usage - Hotkey - toggle annotate/normal mode - Shift-hotkey - show/hide annotation - Ctrl-hotkey - clear annotation - Ctrl-Shift-hotkey - terminate xannotate - Alt-Shift-hotkey - take screenshot (when compiled with screenshot support) . ---* Button usage - Left-click - pen: press to start, move to draw, release to stop - Right-click - eraser: press to start, move to erase, release to stop - Shift-Left-click - switch pen . ---* Command line options There are a few aspects of the program you can control by passing options. ---== -h : brief help -k key : use 'key' as the hotkey (default is 'Pause') -w width : use 'width' as the default pen width (default is 5) -e width : use 'width' as the default eraser width (default is 20) -p path : path/filename for screenshot (default is $HOME/xannotate) -n index : the starting index used for screenshot filename -a : enable alpha for use with XRENDER composite. You must be running an X composite manager (xcompmgr, compton, kwin) for this to work. -1 colour: colour for pen1 (default red) -2 colour: colour for pen2 (default green) -3 colour: colour for pen2 (default blue) ---= ---* BUGS: - The program makes use of SHAPE extension, so it can get slow. You can make it faster by using the alpha (-a) option but you must be running a window manager with composite ability (kwin) or running an independent X composite manager (xcompmgr, compton) otherwise you will get a black screen. - The screenshot only support direct/truecolor, 15/16/24-bit RGB pixel (with LSB first). - Sometimes the shift key can get stuck, just press and release it a couple of times to make it work again. . %=
