Moreover, it is not required for the - cluster values to be monotonically increasing, but pretty much all - of HB's tests are performed on monotonically increasing cluster - numbers. Nevertheless, there is no such assumption in the code - itself. With that in mind, let's examine what happens with cluster - values during shaping under each cluster-level. - </para> - <para> - HarfBuzz provides three <emphasis>levels</emphasis> of clustering - support. Level 0 is the default behavior and reproduces the behavior - of the old HarfBuzz library. Level 1 tweaks this behavior slightly - to produce better results, so level 1 clustering is recommended for - code that is not required to implement backward compatibility with - the old HarfBuzz. - </para> - <para> - Level 2 differs significantly in how it treats cluster values. - Levels 0 and 1 both process ligatures and glyph decomposition by - merging clusters; level 2 does not. - </para> - <para> - The conceptual model for what the cluster values mean, in levels 0 - and 1, is this: - </para> - <itemizedlist spacing="compact"> - <listitem> - <para> - the sequence of cluster values will always remain monotone - </para> - </listitem> - <listitem> - <para> - each value represents a single cluster - </para> - </listitem> - <listitem> - <para> - each cluster contains one or more glyphs and one or more - characters - </para> - </listitem> - </itemizedlist> - <para> - Assuming that initial cluster numbers were monotonically increasing - and distinct, then all adjacent glyphs having the same cluster - number belong to the same cluster, and all characters belong to the - cluster that has the highest number not larger than their initial - cluster number. This will become clearer with an example. - </para> -</sect1> -<sect1 id="a-clustering-example-for-levels-0-and-1"> - <title>A clustering example for levels 0 and 1</title> - <para> - Let's say we start with the following character sequence and cluster - values: - </para> - <programlisting> - A,B,C,D,E - 0,1,2,3,4 -</programlisting> - <para> - We then map the characters to glyphs. For simplicity, let's assume - that each character maps to the corresponding, identical-looking - glyph: - </para> - <programlisting> - A,B,C,D,E - 0,1,2,3,4 -</programlisting> - <para> - Now if, for example, <literal>B</literal> and <literal>C</literal> - ligate, then the clusters to which they belong "merge". - This merged cluster takes for its cluster number the minimum of all - the cluster numbers of the clusters that went in. In this case, we - get: - </para> - <programlisting> - A,BC,D,E - 0,1 ,3,4 -</programlisting> - <para> - Now let's assume that the <literal>BC</literal> glyph decomposes - into three components, and <literal>D</literal> also decomposes into - two. The components each inherit the cluster value of their parent: - </para> - <programlisting> - A,BC0,BC1,BC2,D0,D1,E - 0,1 ,1 ,1 ,3 ,3 ,4 -</programlisting> - <para> - Now if <literal>BC2</literal> and <literal>D0</literal> ligate, then - their clusters (numbers 1 and 3) merge into - <literal>min(1,3) = 1</literal>: - </para> - <programlisting> - A,BC0,BC1,BC2D0,D1,E - 0,1 ,1 ,1 ,1 ,4 -</programlisting> - <para> - At this point, cluster 1 means: the character sequence - <literal>BCD</literal> is represented by glyphs - <literal>BC0,BC1,BC2D0,D1</literal> and cannot be broken down any - further. - </para> -</sect1> -<sect1 id="reordering-in-levels-0-and-1"> - <title>Reordering in levels 0 and 1</title> - <para> - Another common operation in the more complex shapers is when things - reorder. In those cases, to maintain monotone clusters, HB merges - the clusters of everything in the reordering sequence. For example, - let's again start with the character sequence: - </para> - <programlisting> - A,B,C,D,E - 0,1,2,3,4 -</programlisting> - <para> - If <literal>D</literal> is reordered before <literal>B</literal>, - then the <literal>B</literal>, <literal>C</literal>, and - <literal>D</literal> clusters merge, and we get: - </para> - <programlisting> - A,D,B,C,E - 0,1,1,1,4 -</programlisting> - <para> - This is clearly not ideal, but it is the only sensible way to - maintain monotone indices and retain the true relationship between - glyphs and characters. - </para> -</sect1> -<sect1 id="the-distinction-between-levels-0-and-1"> - <title>The distinction between levels 0 and 1</title> - <para> - So, the above is pretty much what cluster levels 0 and 1 do. The - only difference between the two is this: in level 0, at the very - beginning of the shaping process, we also merge clusters between - base characters and all Unicode marks (combining or not) following - them.

If you want to + lay out text that includes a mix of Hebrew and English, you + will need to ensure that each buffer provided to HarfBuzz + has all of its characters in the same order and that the + directionality of the buffer is set correctly. This may mean + segmenting the text before it is placed into HarfBuzz buffers. In + other words, the user will hit the keys in the following + sequence: + </para> + <programlisting> + A B C [space] ג ב א [space] D E F + </programlisting> + <para> + but will expect to see in the output: + </para> + <programlisting> + ABC אבג DEF + </programlisting> + <para> + This reordering is called <emphasis>bidi processing</emphasis> + ("bidi" is short for bidirectional), and there's an + algorithm as an annex to the Unicode Standard which tells you how + to process a string of mixed directionality. + Before sending your string to HarfBuzz, you may need to apply the + bidi algorithm to it. Libraries such as <ulink + url="http://icu-project.org/">ICU</ulink> and <ulink + url="http://fribidi.org/">fribidi</ulink> can do this for you. + </para> + </listitem> + <listitem> + <para> + HarfBuzz won't help you with text that contains different font + properties. For instance, if you have the string "a + <emphasis>huge</emphasis> breakfast", and you expect + "huge" to be italic, then you will need to send three + strings to HarfBuzz: <literal>a</literal>, in your Roman font; + <literal>huge</literal> using your italic font; and + <literal>breakfast</literal> using your Roman font again. + </para> + <para> + Similarly, if you change the font, font size, script, + language, or direction within your string, then you will + need to shape each run independently and output them + independently. HarfBuzz expects to shape a run of characters + that all share the same properties. + </para> + </listitem> + <listitem> + <para> + HarfBuzz won't help you with line breaking, hyphenation, or + justification. As mentioned above, HarfBuzz lays out the string + along a <emphasis>single line</emphasis> of, notionally, + infinite length. If you want to find out where the potential + word, sentence and line break points are in your text, you + could use the ICU library's break iterator functions. + </para> + <para> + HarfBuzz can tell you how wide a shaped piece of text is, which is + useful input to a justification algorithm, but it knows nothing + about paragraphs, lines or line lengths. Nor will it adjust the + space between words to fit them proportionally into a line. </para> </listitem> </itemizedlist> <para> - If this is something that you need to do, then you need a text - shaping engine: you could use Uniscribe if you are using Windows; - you could use CoreText on OS X; or you could use HarfBuzz. In the - rest of this manual, we are going to assume that you are the - implementor of a text layout engine. + As a layout-engine implementor, HarfBuzz will help you with the + interface between your text and your font, and that's something + that you'll need—what you then do with the glyphs that your font + returns is up to you. </para> </section> + <section id="why-is-it-called-harfbuzz"> <title>Why is it called HarfBuzz?</title> <para> - HarfBuzz began its life as text shaping code within the FreeType - project, (and you will see references to the FreeType authors - within the source code copyright declarations) but was then - abstracted out to its own project.
