[Qgis-user] Flatpak

[Raphael Das Gupta]

Heya all

I know that https://qgis.org/en/site/forusers/alldownloads.html#flatpak 
lists the flatpak for QGIS "Stable" (is that the same as LTR?) as 
"experimental", but does anyone at least read issues that are being 
filed? (No offense intended, just genuinely wondering whether this is 
still being maintained.)


I'd be particularly interested in the ones I've filed myself:

https://github.com/flathub/org.qgis.qgis/issues/24 make QGIS 3.4.5 
(latest LTR) available
https://github.com/flathub/org.qgis.qgis/issues/25 Can QGIS 3.6.0 
(latest non-LTR) be installed through flatpack?


I'd like to help with updating the flatpack to QGIS 3.4.5, but can't 
even get its current version (3.4.4) nor the flatpak repo's master 
branch (QGIS 3.6.0) to build locally, yet. 
(https://github.com/flathub/org.qgis.qgis/issues/26 ; though maybe 
that's due to my kinda exotic operating system. But I guess issues with 
the build process are more a topic for qgis-develo...@lists.osgeo.org 
than for qgis-user, anyway?)


Cheers,
Raphael

[Qgis-user] TIFF with paletted band and alpha band interpreted as "multiband color" by default (instead of "paletted")

When I drag-and-drop this file into QGIS (I tried 2.18 and 3 with
identical results) to add it as a raster layer, it is displayed in
bright green: https://i.stack.imgur.com/F6Op8.png

The automatically set display mode (to be found in the "style"
properties) is "multiband color". Only if I manually set this to
"paletted" is the TIFF displayed as intended:
https://i.stack.imgur.com/GNJGs.png

Other software (e.g. GIMP) displays the TIFF as intended without need
for manual color interpretation adjustment.

Is that a bug in QGIS or am I doing something wrong? If a TIFF like this
is valid (I've asked at https://gis.stackexchange.com/q/279584/51574
whether it is), it seems clear to me that a band with a palette should
default to be interpreted according to that palette and an alpha-band as
opacity/transparency, not as e.g. red and green channel.

Raphael Das Gupta


* the linked example image only contains fully opaque pixels but has the
same band structure as the real data that also has fully transparent pixels
