Privacy policy. Your applications can use Uniscribe API functions to support typography and the display and editing of international text. Uniscribe uses the paragraph as the unit for text display, and the Uniscribe functionality must be used for the entire paragraph.
When using Uniscribe for display of text, an application must go through a formatting "layout" process, typically using Uniscribe. The application divides a text paragraph into strings of characters with the same style, called "runs". The style is determined by the particular implementation, but typically includes such attributes as font, size, and color.
In defining runs, the application can also apply other information, such as language and locale data maintained for use with lexical tools. For example, an application might treat as a separate run a passage in a primarily English text that is rendered in French. Once it has determined the runs for all paragraphs, the application divides each paragraph into strings that have the same script and direction "items". The application applies the item information to produce runs that are unique in script and direction and fall entirely within a single item "ranges".
The breakdown of an item into ranges is somewhat arbitrary, although a range should consist of one or more consecutive script-defined, indivisible character groupings, called "clusters. However, in languages such as Thai, a cluster is a grouping of glyphs and corresponds to multiple consecutive characters or code points. For example, a Thai cluster might contain a consonant, a vowel, and a tone mark. So that it does not break clusters, the application typically should either use the longest ranges it can or use its own lexical information to break between ranges in places that are not in the middle of a cluster.
When it has identified the clusters in each range, the application must determine the size of each cluster. It uses Uniscribe to sum the clusters to determine the size of each range. Then the application sums the sizes of the ranges until they overflow a line, that is, reach the margin. The range that overflows the line is divided between the current line and the next line.
For each line, the application builds a map from visual position to logical position for each range. Then the application shapes the code points for each range into glyphs, which it can subsequently position and render. An application does text layout only one time. Afterwards, it either saves the glyphs and positions for display purposes or it generates them each time it displays the text, with the tradeoff being speed versus memory.
A typical application implements the layout process once, then generates the glyphs and positions each time it displays the text. An application that uses complex scripts has the following problems with a simple approach to layout and display. The fact that Uniscribe uses the paragraph as the display unit helps the application deal adequately with these complex script issues.
Uniscribe must be used for an entire paragraph, even if sections of the paragraph are not complex scripts. As shown in the following table, Uniscribe version 1. They can be substituted for the corresponding regular Uniscribe functions.
Generally your applications should work entirely with functions from one set or the other and should not attempt to "mix and match" functions. Your application can use the following steps to lay out out a text paragraph with Uniscribe. This procedure assumes that the application has already divided the paragraph into runs. Optional Call ScriptIsComplex to determine if the paragraph requires complex processing. For information about digit substitution, see Digit Shapes.
