- Background
- ~~~~~~~~~~
- While writing my desktop themes manager, someone asked if it was
- possible to grab colours from the desktop. I didn't know of anything
- that did this, but thought it couldn't be too hard... Yeah right.
- Anyway, this is a stand-alone version used to test the code, which I'll
- no doubt retro-fit into all my other programs at some point.
- ----------------------------------------------------------------------
- Use
- ~~~
- Simplicity itself! Just load the program, click on it's iconbar icon,
- and click anywhere on the desktop with the left mouse button! You can
- carry on using your computer pretty much as normal, but the best match
- for the pixel underneath your mouse pointer is displayed in the ColGrab
- window.
-
- Dragging might be disrupted when ColGrab is working, so to temporarily
- disable ColGrab simply close the ColGrab window!
-
- Points to be aware of:
-
- 1. Dithering: sometimes you'll get colours that don't appear to
- match what you're seeing, and when you move across that same
- "colour" ColGrab will sometimes flick between different shades;
- if this happens, chances are the colour you're looking at isn't
- available in the screen mode you're in, and RISC OS is making it
- out of several colours put very close together to fake it.
-
- 2. Selection: if, when clicking with the left mouse button, the thing
- you click on changes colour (perhaps a filer icon is inverting, or
- the icon changes to something else as with radio buttons) then
- you'll probably get the "after" colour (the inverted colour, or the
- colour of the new sprite as opposed to the old). This can be fixed
- if I add an "always on" option (no need to click on the mouse
- button), but this will slow the desktop down even more.
- 3. Dragging: if you drag an object, or drag a bounding box around
- objects, similar "strange" colouring might happen.

- Release history

- 0.01 First release
-
- Spent the evening getting it to work in a "print directly to the
- screen" kind of way; this application is basically an attempt to put
- a desktop front-end on to it.
