/*
* PDF blend modes:
+ *
* The following blend modes have been taken from the PDF ISO 32000
* specification, which at this point in time is available from
- * http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf
- * The relevant chapters are 11.3.5 and 11.3.6.
+ *
+ * http://www.adobe.com/devnet/pdf/pdf_reference.html
+ *
+ * The specific documents of interest are the PDF spec itself:
+ *
+ * http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/PDF32000_2008.pdf
+ *
+ * chapters 11.3.5 and 11.3.6 and a later supplement for Adobe Acrobat
+ * 9.1 and Reader 9.1:
+ *
+ * http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/adobe_supplement_iso32000_1.pdf
+ *
+ * that clarifies the specifications for blend modes ColorDodge and
+ * ColorBurn.
+ *
* The formula for computing the final pixel color given in 11.3.6 is:
- * αr × Cr = (1 – αs) × αb × Cb + (1 – αb) × αs × Cs + αb × αs × B(Cb, Cs)
- * with B() being the blend function.
- * Note that OVER is a special case of this operation, using B(Cb, Cs) = Cs
- *
- * These blend modes should match the SVG filter draft specification, as
- * it has been designed to mirror ISO 32000. Note that at the current point
- * no released draft exists that shows this, as the formulas have not been
- * updated yet after the release of ISO 32000.
- *
- * The default implementation here uses the PDF_SEPARABLE_BLEND_MODE and
- * PDF_NON_SEPARABLE_BLEND_MODE macros, which take the blend function as an
- * argument. Note that this implementation operates on premultiplied colors,
- * while the PDF specification does not. Therefore the code uses the formula
- * Cra = (1 – as) . Dca + (1 – ad) . Sca + B(Dca, ad, Sca, as)
+ *
+ * αr × Cr = (1 – αs) × αb × Cb + (1 – αb) × αs × Cs + αb × αs × B(Cb, Cs)
+ *
+ * with B() is the blend function. When B(Cb, Cs) = Cs, this formula
+ * reduces to the regular OVER operator.
+ *
+ * Cs and Cb are not premultiplied, so in our implementation we instead
+ * use:
+ *
+ * cr = (1 – αs) × cb + (1 – αb) × cs + αb × αs × B (cb/αb, cs/αs)
+ *
+ * where cr, cs, and cb are premultiplied colors, and where the
+ *
+ * αb × αs × B(cb/αb, cs/αs)
+ *
+ * part is first arithmetically simplified under the assumption that αb
+ * and αs are not 0, and then updated to produce a meaningful result when
+ * they are.
+ *
+ * For all the blend mode operators, the alpha channel is given by
+ *
+ * αr = αs + αb + αb × αs
