Saving file causes print scale issue #1588

Closed dnlombard closed 4 months ago

Expected behavior

File->Save does not corrupt print scale

Observed behavior

Attached is viewed on screen. Page size is "Letter/ANSI A". Select File-Print Preview or select Print Preview from toolbar. Observe scale is 1:1 in the print scale option menu in the toolbar. This is different from the maximum printable scale, 1.63268:1 for attached drawing. Also observe page rectangle is correctly sized relative to drawing. Exit Print Preview. Select FIle->Save or Save from toolbar. Select File-Print Preview or select Print Preview from toolbar. Observe print scale is still shown in the print scale option menu as 1:1, but the page rectangle is now consistent with the maximum scale. Also observe that the maximum scale is no longer included in the print scale option menu. Select 1":1" from print scale option menu and observe that page rectangle changes to expected (larger for attached drawing) size.

While the above discusses Print Preview, the same behavior is observed when the file is printed, i.e., the drawing is printed at the maximum scale (1.63268:1 for attached drawing).

It may well be that Print Preview is intended to always change the scale to maximum and the error is the print scale option menu is not correctly updated.

I cannot reproduce this. Fitting the drawing on page shows a scale of 46.05:1. Version: 2.2.0-alpha Compiler: GNU GCC 11.3.0 Compiled on: Jan 7 2023 Qt Version: 5.15.3 Boost Version: 1.74.0 System: Ubuntu 22.04.1 LTS

The Print Preview is done before printing but it depends on the paper size selected in Current Drawing Preferences which may be not saved to the DXF file. Then it looks normal to set the Print Preview for each LibreCAD session.

I cannot reproduce this. Actually, this was a known issue that was fixed in an older version.
