AddPDFRRasterPageFromJPEGFile

Compliance, raster exchange, file input

Description

Adds a greyscale or RGB JPEG file as one PDF/R raster page without recompressing its DCT data

Syntax

Delphi

Function AddPDFRRasterPageFromJPEGFile(Const FileName: WideString; HorizontalDPI, VerticalDPI: Double; Rotation: Integer): Integer;

Parameters

FileName	Path to a greyscale or RGB JPEG file
HorizontalDPI, VerticalDPI	Explicit resolution, or a value less than or equal to zero to use JPEG density metadata and then the 300 DPI fallback
Rotation	0, 90, 180 or 270

Return value

The one-based page number on success, or 0 when the file is missing, unsupported or malformed

Remarks

The method reads dimensions, colour components and density from the JPEG header, validates the complete byte sequence through the PDF/R image path and embeds it with DCTDecode without transcoding
