LPub3D 2.0 Released

[Jaco van der Molen]

Fix: Page size and orientation processing update (r826/833)
* Further industrialization of the print/export module. This update streamlines the process and realizes some performance gains. There are some key changes. Notably, page orientation and page size are now mutually exclusive. This means when switching from Portrait to Landscape, accompanying the orientation meta with a transposed page size meta no longer required or managed. Here is an illustration:
Previous behaviour when editing a page size change required the following meta commands:
0 STEP
0 LPUB PAGE ORIENTATION LOCAL LANDSCAPE
0 LPUB PAGE SIZE LOCAL 11.0000 8.5000
Note that the page width and height have been transposed. Going forward, transposition of the page width and height when switching from Portrait to Landscape is automatically managed by LPub3D.
NOTE: This update is NOT backward compatable. An accompanying transposed page size meta to indicate the switch from portrait to landscape as shown above will be treated as a new page size meta for that page. Consequently, using this meta to 'switch' orientation will actually result in NOT switching the orientation as LPub3D will automatically switch again the switched page size meta.
If the user is only interested in changing the orientation, the proper meta command going forward will be:
0 STEP
0 LPUB PAGE ORIENTATION LOCAL LANDSCAPE
To help with accurately displaying the page size identifier in the setup and context menus, the standard page identifier is now appended to the page size meta command. For example:
0 LPUB PAGE SIZE 8.5000 14.0000 Legal
0 LPUB PAGE SIZE LOCAL 8.5000 11.0000 Letter
0 LPUB PAGE SIZE LOCAL 5.8000 8.3000 A5
0 LPUB PAGE SIZE LOCAL 5.8678 8.3456 Custom
Along with the width and height values, if the page size is non-standard, the identifier "Custom" will be automatically used. Additionally if an identifier is not present, the identifier "Custom" will automatically used. The page identifier is displayed in the Page Setup dialogue and Size/Orientation change context menu dialogue.
Also, the LPub3D print/export function no longer needs to parse the model file to capture, in advance, page sizes. This capture is performed during the existing page parse and load functions and is exposed to the print routines during printing/exporting. This change was necessary to better enable mixed-size page export/printing where it is necessary to 'look ahead' to get the next page's size and orientation parameters in order to configure the printer engine before processing the page.

Hi Trevor,

I am experiencing difficulty with the page size and orientation.
Setting things up in a new LDraw file does not give the meta for page size like you describe.
In my file setting up the page size A4 and orientation landscape gives this:

0 !LPUB PAGE ORIENTATION GLOBAL LANDSCAPE
0 !LPUB PAGE SIZE GLOBAL 8.3000 11.7000

Opening the page setup dialog sets it to custom size.

My model is rather big (32 by 48 studs). Scaling the assem size to 0.7 should fit, but the image is cut off.
This cut off seems exactly the way it should when the orientation is portrait. So I guess there's something wrong there?
