Print bug with differently sized subsheets [fix requires wxWidgets 3.1.1]

[Chris Pavlina]

An interesting thing happens if you print with certain combinations of differently sized subsheets - but not all combinations. Try this:

Make a schematic with a root sheet and two subsheets.
Set the root schematic and the *second* subsheet (in the order of the hierarchical list) to USLetter.
Set the *first* subsheet to A4.
Print.

The third page will be blank.

It seems to me that the error occurs when you start with a smaller page, move to a larger page, and then go back to a smaller page, but I haven't tried enough combinations to know for sure. This doesn't happen on Plot, only Print (though it does happen if you print to PDF, so no need to waste paper).

Looks like a strange behavior of wxWidgets print system.
It happens also on Windows.

[jean-pierre charras (jp-charras)]

I committed a workaround in revision 5747.

I leave this report open, because the issue is not fixed (I am thinking this is a wxWidgets issue).
At least, with this workaround, the printing does not print a blank page.

I have a similar bug. I have a project containing a sheet and four sub-sheets. when I want to print all sheets in a PDF file, I have the main sheet, the first two sub-sheets, an empty page, and it lacks the fourth sub-sheet (fifth page).
By cons, if I select a single page in the preview, this page will not print.

[jean-pierre charras (jp-charras)]

Without the kicad version, a bug report is not very useful.
This bug is more than one year old.

I have project with the main sheet format A2 and two subsheets A1 and A3

[Dan Weatherill (dan-weatherill)]

I'm not able to reproduce this on current master.
What happens for me is that all three pages have content, but they are all set to US Letter. The A4 page has A4 sized content but printed on a US Letter size page

I believe we can use a DC transform matrix to fix both these issues. Sadly it's only available on MSW until wxWidgets 3.1.1.

Note that the issue in #7 is by-design. If you tell the printer to print on US Letter paper, then we have to scale A4 content to fit.

Scaling the content is good, but also should be rotated in the case you
have some sheets in landscape and some other in portrait mode in the
same schematic.

Now if you have two sheets, one portrait, one landscape, both A4, one is
printed correctly and the other is not rotated but scaled (so the drawn
area ends up being an A5 portrait drawn on an A4 landscape or vice-versa).

Using "plot" to create a pdf does not have the issue.

-Tested on tagged version 5.1.4.
-Also tested on commit 17d015ed5d662ca06b446fda0f84524f8e92006b.

P.S.: I did not test today's commits so if this has been fixed yet...
just drop ths message.

Cheers,
Dino.

[Jeff Young (jeyjey)]

@Dino, the rotation thing has been "fixed", but requires us to move to a more recent version of wxWidgets everywhere except MSW. (I think, anyway. I've no MSW to test it on.)

[Wayne Stambaugh (stambaughw)]

@Jeff, I think this is broken on Windows with wxWidgets 3.0.4 as well. I did some testing and the scaling different sheet sizes and the portrait rotation do not appear to be correct. I've attached images of the print preview of the issues.
