Scan Lines when inserted into Open Office Doc.

Curt Y Jan 31, 2014 11:25 AM

When I insert a picture into Open Office I see pronounced scan lines, even though the picture is only 3x5 inches on a 27 inch screen. If I view same image full screen in photoshop or with Bridge I do not see the scan lines. Have to enlarge photo considerably to see them.

I uploaded the picture to this note and no scan lines were visible. I deleted it as it shows nothing.

So question is does anyone know if Open Office does something to the picture when inserted?

Which program in open office are you using?

What file format is the picture in?

Using Win 7 and jpg picture. It is 3896 x 2672 pixels at 1.9 mb. A little overkill for quality of 110 year old picture.

Here is a reduced quality jpg. It shows lines when inserted into Open Office.

It looks like it's something particular to that file.

If i turn off Use Graphics Processor in photoshop, then i can see the same thing as open office shows, depending on the view % in photoshop.

If in photoshop i run the Filter>Pixelate>Facet one or two times and then save the file as a tif, it looks much better in open office.

Ran filter/pixelate/facet once and saved as jpg and it cured problem.

You are a storehouse of knowledge.

Thanks.

The image is a scan of a halftone -- it really does have lines if you look closely.

The pixelate filter stills leaves some of the lines, so you might try some gaussian blur (just enough to get rid of the lines) and then some smart sharpen set to gaussian blur with a radius equal to or less
than the gaussian blur amount to compensate for the blurring.

I saw some of the lines in photoshop cc, but it wasn't till i opened up the jpeg Curt posted in photoshop 6, that i really could see the lines clearly.

After i turned off Use graphics processor in photoshop cc, then i could see the lines clearly.
