White Vertical Line through Viewport

leedeetee · 29 Nov 2010, 15:04

I'm encountering an annoying problem that whenever I print from Layout, I get a very noticeable white line down vertically, through the middle of each viewport.

I initially thought it was the axis somehow being printing out, but this in the wrong position for this to be the problem.

Any thoughts on this? It's extremely annoying!

IS this a LO error, or a Printer one?

(I could scan in an example if it was to help.)

If you export to PDF do you see this white line?
Depending on your PDF viewer you can select items in
the PDF file. In my viewer (Acrobat Reader) I can select
the SU model and it will highlight the SU model bitmap.
If you select your model, does it highlight a bitmap right where
the white line is showing up?

Thank you for getting back to me.

When I export to pdf, I do not get the white line, but when I click on the image, the SU model bitmap seems to be split into two halves, exactly where the line appears on the print-outs.

I have attached the .pdf for reference.

Thank-you.

The image is indeed exported split this way (I guess it has "economical" reasons and you can export quite large ones this way).

Anyway, just print your export as a workaround (I prefer exporting first anyway)

So is this split causing the white line?!

I don't know, Lee. I do not even have a printer and have never tried to print a LO document in my life.

I have not heard this yet however. Seems logical though but I do not know why it is happening. You know, I am one of those Joe Averages when it comes to technical details

The SU model is tile rendered, so there's 2 images in this case.
The models are tile rendered to get around memory issues, otherwise
the drawing/rendering of large bitmaps fails.
The white line is the space between the two images. Note that
you don't see a gap between the images in the PDF file. The
white line/gap is precision problems of the printer.
Does the white line show up when printing from the PDF viewer?

No it doesn't. So I'm guessing export to pdf is the answer. Or getting the printer guys out! Suppose this is a good workaround, albeit adding a few extra seconds to the workfklow and a few more megabytes to the project folder.

Thanks your your comments and help, really appreciate it.
