Appearance (Apparenza)

Le preferenze in Appearance permettono di cambiare alcuni aspetti visivi di Haiku .

Colori

Nella prima tab, Colori, puoi cambiare i colori di diverse parti dell'interfaccia utente. Il colore accetta anche drag&drop da altri programmi, permettendo di prendere colori da, per esempio, WonderBrush, Icon-O-Matic o dal pannello di Backgrounds.

Antialiasing

The second tab, Antialiasing, provides different settings for how things are rendered on screen.

Glyph hinting

An activated Glyph hinting aligns all letters in such a way that their vertical and horizontal edges rest exactly between two pixels. The result is a perfect contrast, especially when dealing with black on white. Text appears crisper. There's also a setting for Monospaced Fonts Only that's especially helpful with low resolution devices like netbooks. Small fonts can look pretty bad when hinting is turned on, but with this setting you still have the advantage of hinting for text editors and Terminal.

See the difference hinting makes with these magnified screenshots:

Hinting: off

Hinting: on

It should be pointed out that all the Magnify windows on this page are of course rendered themselves with the different options as well. So, you get a real world impression of the settings by comparing, for example, the bold yellow tab title or the text "33 x 15 @ 8 pixels/pixel".

Antialiasing type

Another technique to improve rendering is Antialiasing, which supports all vector graphics as well as text. It smooths lines by changing the color of certain pixels. There are two methods for that:

Grayscale changes the intensity of pixels at the edge.
LCD subpixel does an even better job, especially with (high resolution) LCD monitors. Instead of the intensity of a pixel, it changes its color which moves an edge by a fraction of a pixel, because LCD displays produce every pixel with a red, green and blue component.

Again, the two different methods with magnified screenshots:

Grayscale, Hinting: off

LCD subpixel, Hinting: off

Subpixel based antialiasing adds a slight colored shine to objects. Something not everyone tolerates. In Haiku you can mix the two antialiasing methods and find the right setting for you by using a slider.

If you do activate hinting plus LCD subpixel rendering by changing the source and recompiling, this is how it looks compared to hinting with Grayscale:

Grayscale, Hinting: on

LCD subpixel, Hinting: on

Nel fondo del pannello ci sono due pulsanti:
