TC10.50b5: Lister help about printing picture is incomplete

The behaviour described in the bug report is either by design, or would be far too complex/time-consuming to be changed

TC10.50b5: Lister help about printing picture is incomplete

Post by *Slavic »

Currently, there is a few info in Help about printing a picture from Lister:
Furthermore, pictures can be printed too. In the mode 'Shrink bitmap' the picture is shrunk to the size of the available print area, and also enlarged, if it was smaller. Otherwise it is printed in 1:1 size.
First of all, currently there is no "Shrink bitmap" mode, we have two fit options instead. Apparently "shrink" means the "Fit image to window" mode.

Now about printed size:
From my test (Print to XPS in Windows 8.1, format A4 portrait) with default Lister settings, large pictures are always resized to paper size, no matter whether one of two Fit modes is selected or not. Enlarging a small picture happens only for "Fit image to window" mode when the picture is also shown enlarged on the Lister's screen. In "Fit only larger images to window" mode the small pictures are printed 1:1 like without a fit.
Finally, any user-selected zoom does not affect printing at all.

It would be reasonable to improve the help section about printing to reflect existing rules.

Well, that's what "Fit only larger images to window" means: Larger images are shrunk to the window/print area, while smaller images are not.
Finally, any user-selected zoom does not affect printing at all.
Zoom mode is new and doesn't support printing yet. I agree that the situation isn't good - better use a program with print preview for images like Irfanview.

In TC10.50b6, the Print... part of Lister menu help is extended, it describes the printing as it is implemented now.
So, the Help is fixed, thanks!

As for changing of printing logic in the case of user-selected zoom, it's not a bug rather than a suggestion.

Supporting zoom without preview would be a bad idea, a lot of wasted paper until the right size is achieved.
