Re: [Qgis-user] colorramp starting from white

[Thayer Young]

 Hi Raymond,
I agree with you that the color ramps should be easier to distinguish from the 
default background color. The workaround that I have been using recently is to 
set the background color to something else besides white. You can do this from: 
QGIS | Preferences | Canvas & Legend It is not very satisfying though, and does 
not solve the problem of what if you have more than one ramp on different 
layers on the same map canvas? I have actually been calculating ramps outside 
of QGIS and saving them as SLD files then load that style into QGIS.

Message-ID: 
Content-Type: text/plain; charset=utf-8; format=flowed

Am I the only one who would like the color ramps in QGIS to NOT start 
from (super nearly) white, but from a light version of the color?

For example, "Reds" should go from (light) pink to red.

Currently, the first class in my legend always looks white, as many 
other parts of my map often do. Therefore it is hard to see where my 
data is and where not.

Another thing, changing it manually is hard because of the 7 stops in 
the ramps.

I'm happy to figure this out and make a PR, but would like to know 
other's opinions first.

Regards,
Raymond

Re: [Qgis-user] [Qgis-community-team] Fwd: documentation v 3.10 - PDF ?

[Alexandre Neto]

Hi again,

Travis is returning an error because I have added pdflatex to the
requirements. I think the problem is that we are still using a 16.04
machine, with python 3.5 in Travis and PDFLAtex is only available on pip in
python >= 3.6

Is there a reason to keep this old setup for travis, would it make sense to
upgrade? at least for 18.04 now that 20.04 already available. Otherwise, I
can simply remove the requirement

https://travis-ci.org/github/qgis/QGIS-Documentation/builds/699870137

Thanks,

Alexandre Neto

Hi,

Based on some work done by Richard and Håvard, I have tried to revive the
ability to create PDFs for the main documents.

https://github.com/qgis/QGIS-Documentation/pull/5729

I only tested with English outputs, but I hope it works with most languages
too.

I have a virtual instance of Ubuntu 20.04 installed on my home computer and 
have successfully installed 3.10.4 from the standard Ubuntu 20.04 repositories. 
 I suspect that you have different libraries and versions of QGIS left over 
from your 18.04 installation and it may be complicated by the possibility that 
you may have used the UBUNTU GIS PPA to install your previous version.Hard 
for me to tell without more detail.

I would suggest that you use aptitude search to find all instances of gdal, 
grass, proj, and qgis that you may find and remove them with apt.  Then start 
with a simple qgis installation using apt.

You can also make a virtual instance of 20.04  ( using KVM) and install qgis 
there.  I nfs mapped my base systems drives to the virtual instance to access 
my data on the base system.

Good luck!

Re: [Qgis-user] How to determine the inner surface on a sphere or ellipsoid

[Tudorache, Marian]

I think I found a solution for this problem.
Instead of do the analysis over the entire polygon on the surface, I will do it 
over the three consecutive points from polygon vertices not colinear and the 
middle point is either most East, South, West or North.
detO = (bPoint.x() - aPoint.x()) * (cPoint.y() - aPoint.y()) - (cPoint.x() - 
aPoint.x()) * (bPoint.y() - aPoint.y())
The sign of the determinant will tell me the direction of the three points 
which coincides with the direction of the polygon.
In this way I can force the orientation of the polygon to match the one 
required by Intermaphics.

Thanks,
marian

That's just a convention -- it doesn't change what the boundary actually 
represents.

If you want to do analysis based on points which fall outside a digitized 
polygon, you should use a "disjoint" relationship. The alternative is to do 
what Nicolas suggested and make a polygon which covers the globe minus a small 
hole, but you'll get terrible performance with any analysis using that 
approach...!

[Qgis-user] How to change the color of the labels for features that are selected

[Tudorache, Marian]

Hi everyone again,

When I select in QGIS the selected features are highlighted in a different 
color but if the labels are turned on, they do not change the color.
Is it a way to change the color of the labels for the features that are 
selected and keep the others with the original color?

Thank you,
Marian

[Qgis-user] (no subject)

[Maria Fernanda Obando Picado]

Hi! Thanks for incluiding me.

I changed from Ubuntu 18.04 to Ubuntu 20.04, so I automaticly lost the qgis
software. When I tryed to install it again, many troubles came out, like
"qgis needs 'this' or 'this' but its not going to be install" or 'its going
to install 'this' in stand of 'this'; "E: the package its not found" and
also "you have broken packages". I tryed to erase old packages, tryed to
clean caché, tryed commands like "autoremove", "autoclean", "sudo apt-get
-f install' and i followed all the suggested steps from the qgis original
tutorial but nothing worked!

Its there any other suggestions about how to install qgis? this vertion is
actually working?  I even tryed to install qgis copying from the terminal
to the repository both latest versions (https//:qgis.org/ubuntu and https//:
qgis.org/ubuntu-ltr)

Please, anything will help, i'm in the middle of my final work to get a
master degree and i already lost 2 days trying to fix this. My plan B is
just, get back to Ubuntu 18, but its possible that that doesnt work easily
anyway.

Thanks for your atention!

To share the complete project with all layers and styles its best to ‘package’ 
up the whole project. Check out the qPackage plugin.
