[darktable-user] Using a Wacom tablet

[Johann Spies]

I bought myself a Wacom tablet and am learning how to use it.

One thing I could so far not figure out is how to imitate the scrolling
(mouse wheel) to resize for example the brushes when using a drawn mask.

How can I change the size of those brushes with a Wacom stylus and tablet?

I work on Debian and did not see any options in the Darktable preferences
regarding the Wacom tablet/stylus as input device.

Regards
Johann

Re: [darktable-user] Manual in EPUB format

[J Albrecht]

Tony,

You don’t have to save it as an EPUB. Calibre indexes and opens pdfs without a 
problem! Furthermore, by not converting to EPUB, you’re avoiding the funky 
formatting that often happens as a result of the process.

Re: [darktable-user] Parametric Mask Question

[Ulrich Pegelow]

These are offered in modules that work in the RGB color space.

The grayscale value g is calculated as 0.3*R + 0.59*G + 0.11*B - that's 
a simple and rather common way of weighting the individual channels to 
get a grey image.


OTOH the L value is calculated out of a RGB -> HSL color space 
conversion. We could have left L out of the offered channels but as we 
anyhow wanted to allow users to select on Hue and Saturation the L 
channels came as a cheap add-on.

In some instances (for instance the channel mixer) the parametric masks
offer scales in both 'g' (gray-scale) and 'L' (lightness). How do these
scales differ?

[darktable-user] Manual in EPUB format

[Tony Arnold]

Is there an EPUB (or other ebook format) version of the darktable manual 
available? Or how might I go about creating such a version?

I ask, as every now and again I take a look at Calibre to organise documents. 
It can handle PDF docs, but I think EPUB or some such may be better suited.

Any help greatly appreciated as always.

Regards,
Tony.
