exported png file + draw format + file in gimp


Ubuntu 14.04 / LO

- create a document (page size A3) in draw
- export it to .png
- set size and resolution, no interleave, in dialog box

What I expect :

- a png file of same size and proportions,
- in that case a red rectangle with 1cm white border.
(or a red rectangle with 1cm transparent border)

What I get :

- the png export excludes the margins of the original A3 document but size remains A3 420x297mm so resolution lowered,
- in that case only a red rectangle.

…resolution lowered,


proportions of the image are not kept

(as you can see on attached gimp picture, horizontal and vertical resolution are different)

I wonder, if bug 91768 is related.

Win 7 Pro 64-bit Version:
Build ID: 902255645328efde34ddf62227c8278e8dd61ff0

Comment 3 Gérald Maruccia 2015-08-01 15:39:25 UTC
Indeed bug 91768 seems very similar.

If exported without keeping transparency, from the same image, you get 1cm white border, expected size and proportion.

So there is a confusion mixing :

- actual size of "page"

- margin/border of this page

- transparency


Transparency or not, in my mind, the size of the image should remain the size of the "page" it's on.

Comment 6 Gérald Maruccia 2016-09-20 12:45:13 UTC
Problem is still present in
Build ID: 1:5.1.5~rc2-0ubuntu1~trusty1

Attached are 3 png files in test_3_png_files.zip

Settings of the page are :
A4 size,
top and bottom margins 4cm
left and right margins 2cm

test_01 no transparency → ok
test_02 with transparency → not ok, stretched, wrong proportions
test_03 is what I expected, made with gimp from test_01.

This issue of margins left out in transparency exports is tracked in bug 89828.
