Description renn0xtek9 2015-01-06 10:27:21 UTC
1)Draw whatever with libreoffice
2)Export it to png with default settings.
3)Open the .png
4)See how you entered the 22nd century with pixels almost as big as an apple.

I am sure it is thinkable to do so that defaults settings save in High Definition (At least Microsoft Office can think of doing that)


Second nobody understand how to change the settings 
(Why the fuck changing pixel per centimeters should change the size of the image???) 
in other word, if I want to increase the pixel density the image size MUST stay identical !

Best regards

TESTING with LO 4.3.5.2 + Ubuntu 14.04

I drew a big smiley face

> 2)Export it to png with default settings.

8.5" x 11" image, with resolution of 37px/cm
(Side note: I filed bug 88132 re: mixed units)

> 3)Open the .png

I used GNOME's eog.

As in an Apple computer, or the pomaceous fruit?

The pixels don't look too huge to me, but maybe I don't have a huge/high-res screen?

Defaults can always be changed, but there's a trade-off between resolution and file size. What would you suggest for a default resolution?

Status -> NEEDINFO

(Please change status to UNCONFIRMED after you've provided the info)

If I open the export dialog (File -> Export -> (choose in the drop-down) PNG), then I can change the Width, Height, or Resolution.

Changing the Width/Height does not affect the Resolution, but changing the Resolution does cause the Width/Height to change. I agree that this doesn't seem optimal to me, but I believe I've seen this behavior with other programs that handle raster images, so perhaps there's a good reason?

Well if you want to print it, ti me 37px/cm is far too low.
If you insert the png in a pdf, one will see that it is not sharp at all
