Hello everybody, I have some problems with PI7.

1. I save a page of a pdf file as tiff (monochrome, fax 4 compression, 300 dpi). Upon opening the picture in PI7 it says that is of 301 dpi resolution. Why is that?

2. A tif file saved from PI7 with abovementioned settings appear inverted when opened with IrfanView, although when inserted in a word document appears correctly.

3. *most important*
After editing the picture from pt. 1 (added some text on it) and saving it, PI7 cannot open the picture anymore. If I modify the resolution to 300 dpi, PI7 opens the picture.

what should be the problem?

Thank you very much
