Description wotan 2014-06-17 14:36:09 UTC
Create a drawing on a A4 page
go to File export
export to png
save the file

Open the file with an image viewer
1) The resolution is more or less similar to the very first Game boy that is to say pixel as big as an Apple. This is not what the user is awaiting from its 4 core computer HD graphic card
2) The default exporting parameter should perform high resolution exporting. User should not play with parameters for doing this
3) Exporting parameters are abstruse anyway, it is impossible to understand how it works
Comment 1 Regina Henschel 2015-01-19 18:19:46 UTC
The default resolution is that of your monitor, for me 120dpi. I see no error in using the monitor resolution as default.

I do not think, that the default should be a resolution for printing, which would be at least 300dpi. If you have got a content, which does not compress well, the file size will be large. For which purpose do you need such a large resolution?

First set the desired resolution, then width or height. That is not difficult. But perhaps someone likes to add a wizard for exporting images.

The purpose: 
1) you draw something,
2) you export it in png
3) you import the image in writer

( 2) +3) ) are becasue generally importing draw document into writer is a fail...

4) you don't wan to see big pixel in the image that bring you back in the 80s... 

About resolution:

Basically we shall just copy the behavior of MS Office. When Visio export a drawing to image, it works well, no one complain about, no one need wizard and tuning dodgy parameters.

TESTING with LO 4.4.0.2 + Ubuntu 14.04

REPRO Steps
> The purpose: 
> 1) you draw something,

- Open Draw
- Create 'test-document-in-draw_fdo80138.odg' (attachment 112622 [details]) that contains 
  - A smiley face
  - A triangle
  - A 5-point star

> 2) you export it in png

File -> Export -> PNG (attachment 112623 [details])

Default options are:
 Width: 8.5"
 Height: 11"
 Resolution: 37 px/cm

 Filesize is 43.4K

> 3) you import the image in writer

- Create new Writer document
- Insert -> Image -> (select file) test-document-in-draw_fdo80138.png

> 4) you don't wan to see big pixel in the image that bring you back in the
> 80s... 

Image looks a bit distorted, so
- (right click) -> Image -> Type -> Size -> (click button) "Original Size"
- Save file  (attachment 112624 [details])

That looks MUCH better.

The image quality looks pretty good, and the same in LO and EOG (attachment 112625 [details]). I don't see any huge pixels, etc.

So NOREPRO from me.


wotan: What do you see here? Is this a HIDPI issue?
