Hi António:
I have just pushed your (modified) commit plplot-5.14.0-12-gaa0dd85fc.
(By the way, "plplot-5.14.0-12-gaa0dd85fc" is the result of
"git-describe aa0dd85fc" which is a convenient way to show aa0dd85fc
is the 12th commit after plplot-5.14.0.)
Congratulations on this result! Your code
Hi Alan
glad things have solved out. You gave a full explanation my approach was
more intuitive.
as for testing I haven't performed nothing formal. in fact I have a qt gui
application with the ex01c and i usually play with it to figure things up.
Not a standard plplot way of doing things
but here

Just one more thing
the fact that a single RGB seems to work when you have a kind of
semi-transparency a layer is easily explained because one is saving only
the RGB resulting from the merge operation no need to save the alpha value

Hi Alan
you must revisit the -bg comand argument.
you are right with your command either with the changed version or with the
original version one gets the opaque blue
but let us put exactly the same directly in code.
plscolbga(0,0,255,0.1);
plinit();
and then perform the command
./x30c

I'll try to answer your question. But first a little clarification in my
system example 30 works exactly the same way with my changes or without
them.
But really that was not the question. just try to put in xo1c example

Here are two alternative suggestions:
"Fix background transparency in the raster qt Drivers"
or
"Fix transparency in the raster qt Drivers"
Let me know which of these you prefer.
P.S.
That should have been "raster qt devices" rather

Hi Alan
I think the small change I purpose will do the trick. In no way it will
mess up with the normal functionality of the driver but it will allow all
qt drivers to be used inside a qt
program. I've tested it.
I Think Alban Rochel never considered necessary to use the drivers from a
qt program

Glad to be of some help.
Really that empty string in family name especially when the matchof name is
not an exact match could have strange results and could vary from system to

still need different things as

Hi Alan thanks for this detailed explanation. The inclusion of helvetica
