This panel allows you to tune the visual attributes of the screen menus within T/HIS and save them if you wish.

Display Factor

Lies in the range 0.5 to 2.0, default 1.0. Values < 1.0 reduce the apparent size of the screen so that menus and text become larger. Values > 1.0 act in the opposite sense. This is the simplest way of taking into account the display size.

Font Size, Quality and Scaling

On most displays the Default font size will give the best appearance in menu interface panels, but occasionally Small or Large fonts may look better. It is recommended that you set the Display Factor first in order to get the best overall layout on your display, then adjust the font size if necessary.

Font quality improvements were made for T/HIS 17.0, and on most displays Proof quality will look best. However on low resolution displays it may look a little fuzzy due to the anti-aliasing process, and Anti-alias (coarser) or Plain (not anti-aliased) may give a crisper result.

Font scaling (Permit scaling) can be useful when your choice of font is a bit too large for the buttons in the user interface, since it allows the default font size to be reduced where text would overflow the space in a button. However it can result in a mixture of font sizes in a panel, which might improve legibility but looks untidy, so it is generally better to choose a Display Factor and Font Size that work well together on your display, and turn Scaling off.

Cached fonts is an obscure setting that will only apply on Linux systems where the "core" X11 font package has not been loaded, and the software reverts to cached bitmaps. If you have font problems on Linux please contact Oasys Ltd Support for advice and help.



Font selection

Historically T/HIS only provided Helvetica, Times and Courier fonts, but from T/HIS 17.0 a wider range of fonts has been made available.

The default for the User interface is still Helvetica for menu panels (the "Menus font") and Courier for listings (the "Listing font"), but you can use the popup menus to select from any of the fonts on your computer. The range of fonts available will depend both on the operating system and what has been installed, but typically there can be many. To try to make the choice manageable these are separated into

Proportionally spaced fonts, where character width varies. This is preferred for GUI panels with buttons.
Monospaced fonts, where each character width is the same. This is preferred for text listings.

Within each category fonts are also sorted by weight, with "normal" being the most commonly used. "Light" options tend to be narrower, permitting more characters to fit in a button, "Heavy" options tend to use bold text, and can be useful when using very large fonts - perhaps on a projector or when setting up the user interface for someone who is visually impaired.
Brightness

Lies in the range 0.0 to 1.0, default 1.0. Controls the brightness of the menu interface only (it will not affect displayed graphics).

Saturation

Lies in the range 0.0 to 1.0, default 1.0. Controls the colour saturation of the menu interface. (Again it will not affect displayed graphics.)

Left Handed

The software uses mouse buttons and keyboard 'meta settings keys (<shift> & <control>) in a handed way that is set up by default for right-handed use. It is possible to configure either or both for left-handed use.

Save Settings

Once you have adjusted the above to your taste you can save these settings in your 'oa_pref' file for future use with the Save_Settings button. If you do not save settings they will be lost when this session exits.
