Underlined text disappears when zoomed out

Version of Archi

4.9.3

Operating System

Windows 10 Entreprise

Expected Behaviour

When zoomed out, name of elements should be displayed

Actual Behaviour

When zoomed out, name of elements when underlined is invisible. I've observed the same behaviour with all fonts I've tried.

Steps to Reproduce the Behaviour

1. Create any element in a view, set a name
2. Change Appearance > Font, check "underlined"
3. Zoom out the view until the name of the element disappears

Thanks for the report, which I can confirm (also with Strikeout)

It turns out that this is a side-effect of fixing problems with fonts not displaying properly when we stopped using the Draw2d class ScaledGraphics. See https://github.com/archimatetool/archi/issues/621

One of the things that the Draw2d class ScaledGraphics does is to handle scaling of fonts with with these text styles (but with certain problems which is why we no longer use it.)

Some observations:

• Underlined text is also not drawn when exporting to SVG (this has always been so)
• The Underline and Strikeout options in the font dialog do nothing on Mac and are not present on Linux (Mint) so this is Windows only
• The Modelio tool also encountered the same issue and doesn't use ScaledGraphics. See here. They have removed the additional font effects from the font dialog (Underline, Strikeout and Colour) probably for this exact reason.

So what can we do?

1. Go back to using ScaledGraphics, or
2. Remove the extra text style options from the font dialog as Modelio have done in their tool
3. Leave things as they are and note that underline only renders at 100% zoom

Option (1) is not going to happen. I'd have to reverse months of work and we'd be back to having issues with clipped fonts. So perhaps option (2) would ensure consistency among platforms.

Regarding the ScaledGraphics class, it seems that it was regarded as needing to be removed or replaced some time ago:

Remove the extra text style options from the font dialog

This is what I'll do for the next version. Pointless to have underline on only Windows and doesn't zoom.

I'll close this as can't be changed.
