Example 1 with ReplacementSpan

use of jp.sblo.pandora.jota.text.style.ReplacementSpan in project Jota-Text-Editor-old by jiro-aqua.

the class Styled method drawUniformRun.

/**
     * Draws and/or measures a uniform run of text on a single line. No span of
     * interest should start or end in the middle of this run (if not
     * drawing, character spans that don't affect metrics can be ignored).
     * Neither should the run direction change in the middle of the run.
     *
     * <p>The x position is the leading edge of the text. In a right-to-left
     * paragraph, this will be to the right of the text to be drawn. Paint
     * should not have an Align value other than LEFT or positioning will get
     * confused.
     *
     * <p>On return, workPaint will reflect the original paint plus any
     * modifications made by character styles on the run.
     *
     * <p>The returned width is signed and will be < 0 if the paragraph
     * direction is right-to-left.
