Bug report #6185

Updated by Alister Hood almost 2 years ago

Make a jpeg file read-only.

Load the jpeg into QGIS.

Right-click the jpeg layer in the TOC

Choose Properties>Pyramids

Select a pyramid resolution and click the "build pyramids" button.

You will get an error message: "Write access denied>Adjust the file permissions and try again".

But the file permissions on the jpeg file should not matter, because the pyramids would be saved in a separate .ovr file!

I believe the same should apply regardless of the image format, as long as the option "Build pyramids internally if possible" is not selected.
