CHAPTER 8

Text and Ink Input and Display

Using Text 8-17

You can modify the size at which ink words are displayed in two ways: by

changing the scaling percentage or the font size. For example, suppose that you

draw an ink word and the system calculates its font size, as written, at 36 point. If

your ink text scaling is set to 50 percent, the ink word is displayed at half of the

written size, which makes its font size 18 point. If you subsequently change the

scaling of that ink word to 100 percent, its font size changes to 36 point.

If the user applies deferred recognition to the ink words, the recognized text is

displayed in the current font family, size, and style, as speciﬁed in the Styles menu.

Note

There is a maximum ink word size. Ink words are scaled to the

smaller of what would be produced by the selected scaling

percentage or the maximum size.

Constraining Font Style in Views 8

You can override the use of styles in a paragraph view so that all of the text in the

paragraph is displayed with a certain font speciﬁcation. To do this, use the

viewFont slot of the paragraph view along with two of the text view flags.

If you include

vFixedTextStyle in the text ﬂags for a paragraph view, all

recognized text in the view is displayed using the font family, point size, and

character style speciﬁed for viewFont. This is the normal behavior for input ﬁelds.

If you include

vFixedInkTextStyle in the text ﬂags for a paragraph view, all

ink words in the view are displayed using the point size and character style

speciﬁed for

viewFont. Note that the font family does not affect the display of

ink words.

Note

Using the vFixedTextStyle or vFixedInkTextStyle ﬂags

does not modify the

'styles slot of the view. However, if you

use either of these ﬂags, the system does not allow the user to

change the text style for your paragraph view.

◆

The text view ﬂags are described in “Text Flags” (page 7-2) in Newton

Programmer’s Reference.

Using Fonts for Text and Ink Display 8

Whenever recognized text is drawn on the Newton screen, the system software

examines the font speciﬁcation associated with the text to determine how to draw

the text. The font speciﬁcation includes the font family name, the font style, and

the point size for the text. You can specify a font with a font frame or with a packed

integer; both of these formats are described in this section.
