Struct pdfium_render::color::PdfColor

pub struct PdfColor { /* private fields */ }

A 32-bit RGB color value with an optional alpha channel.

Certain basic primary colors are available as const values on this struct.

Note that when used as a form field highlight color, a solid color with no opacity will overprint any user data in the field. Use the PdfColor::with_alpha() function to apply an alpha channel value to an existing PdfColor.
