I have create whit qgis essen various maps. Because i have memory limitation, i have spend a lot of cash for a new pc.
Now i have copied/migrate my file to the new pc (WIN10pro) and installed qgis madeira. If i now will export as png image, qgis crashes with follow crashlog:
**QGIS Info QGIS Version: 3.4.10-Madeira QGIS code revision: 3d97aaae88 Compiled against Qt: 5.11.2 Running against Qt: 5.11.2 Compiled against GDAL: 2.4.1 Running against GDAL: 2.4.1
System Info CPU Type: x86_64 Kernel Type: winnt Kernel Version: 10.0.18362**
In the composer/printer dialog, i are unable to set the image resolution (e.g. 5000x3000px): why that? All message window, that appear after click on ok in the composer window, will show wrong file info, e.g.crate file 3500x2500px, but in reality is it estimate 12'000x9000px.
After that, i have installed on the same new pc qgis essen. I have must set the resolution to 50px to export a map due the memory warning dialog. I have chek the taskmanager, and have noticed that qgis use max. 6% from the RAM (and i have spend a lot of cash for the new pc!!!!!). All exported images with 50px are unreadable/blured due low resolution. It seems, that also qgis essen have problem to reserve RAM on the new WIN10 computer.
After that, i have try again qgis madeira. After importing a print layout, qgis will export images, but they are all wrong (wrong image resolution e.g. 3700x2500px) and empty.
After that, i have create a new print layout, an qgis will crash when they will export the image (see crashlog above), and all info about the exported image are wrong (wrong image size and resolution).
Currently i are very frustrated, because i have spend over 4000 buks for the new pc with 192MB RAM, but qgis will not work: i assume that the OS (WIN10) are the cause.
Question: have anybody experience with ubuntu and qgis and printing large maps (over 5000x5000px and min. 150px resolution, if possible over 10'000x8000px)? Any suggestion and tip are wellcome!
In conclusion, i will advise all people, do not spend cash for qgis to print large maps, because at this time qgis on WIN10 is unable to export large maps as png. Franc
