[Qgis-developer] Printing 25k raster maps

[uk52rob]

Hi Marco,

Interestingly, I have done some research on this last night and this
morning, and it appears to be an issue with the rendering of the print.

For some reason, the 25k raster layer is only filling the top 1/3 of the
print, with the 250k raster layer underneath then becoming visible for the
other 2/3.

I have created a new project, put the 25k raster in, created a new print
composer and printing the map alone works fine.

However, I have just created my current project again from scratch to ensure
no project file errors occurred when moving from 1.6 to 1.7, and the same
happens!

If I remove the underlying 250k raster layer, the lower 2/3 of the print
becomes blank, with only the vector shapefiles displayed.

When I export this to a PDF, it turns out fine, but you can see Acrobat
Reader rendering the first 250k layer, then the overlaying 25k layer, so I
wonder..

I printed another project fine, so I just don't know what to do with this
one!

Cheers,

Rob

Hi Rob


Just tested here and I can print my 1:25k maps here (geotiff though).

Do you have the possibility to make an example available (or send it to me 
privately)? Please open a bug ticket with exact description of steps (e.g.
if 
you print to printer, export as pdf, export as image, operating system
used).

Regards,
Marco
