Text

A Text object contains text.

new Text()

Constructor method.

Create a new empty text object.

Returns:

Text.

EXAMPLE

var text = new mupdf.Text();

Instance methods

showGlyph(font, transform, glyph, unicode, wmode)

Add a glyph to the text object.

Transform is the text matrix, specifying font size and glyph location. For example: [size,0,0,-size,x,y].

Glyph and unicode may be -1 for n-to-m cluster mappings. For example, the “fi” ligature would be added in two steps: first the glyph for the ‘fi’ ligature and the unicode value for ‘f’; then glyph -1 and the unicode value for ‘i’.

Arguments:
  • fontFont object.

  • transform[a,b,c,d,e,f]. The transform matrix.

  • glyphInteger.

  • unicodeInteger.

  • wmode0 for horizontal writing, and 1 for vertical writing.

EXAMPLE

text.showGlyph(new mupdf.Font("Times-Roman"), mupdf.Matrix.identity, 21, 0x66, 0);
text.showGlyph(new mupdf.Font("Times-Roman"), mupdf.Matrix.identity, -1, 0x69, 0);
showString(font, transform, string)

Add a simple string to the Text object. Will do font substitution if the font does not have all the unicode characters required.

Arguments:
  • fontFont object.

  • transform[a,b,c,d,e,f]. The transform matrix.

  • string – String content for Text object.

EXAMPLE

text.showString(new mupdf.Font("Times-Roman"), mupdf.Matrix.identity, "Hello");
walk(textWalker)

Call the showGlyph method on the textWalker object for each glyph in the text object.

Arguments:
  • textWalker – The text walker object. A user definable JavaScript object which can be used to trigger your own functions on the text methods.

EXAMPLE

text.walk({
    beginSpan: function (font, transform, wmode, bidilevel, markupdirection, language) {
        // ... do whatever ...
    },
    showGlyph: function (font, transform, glyph, unicode, wmode, bidilevel) {
        // ... do whatever ...
    },
    endSpan: function () {
        // ... do whatever ...
    },
});
