AddPDFRRasterPageFromStream

Compliance, raster exchange, stream input

Description

Reads a binary stream and adds one full-page PDF/R raster strip

Syntax

Delphi

Function AddPDFRRasterPageFromStream(InStream: TStream; Width, Height, BitsPerComponent, ColorModel, Compression: Integer; HorizontalDPI, VerticalDPI: Double; Rotation: Integer): Integer;

Parameters

InStream	Non-empty seekable stream containing raw packed samples, CCITT Group 4 data or a complete JPEG sequence; reading starts at byte zero
Width, Height	Raster dimensions in pixels
BitsPerComponent	1, 8 or 16 as permitted by the selected colour model and compression
ColorModel	`PDFR_COLOR_BITONAL`, `PDFR_COLOR_GRAY` or `PDFR_COLOR_RGB`
Compression	`PDFR_COMPRESSION_RAW`, `PDFR_COMPRESSION_CCITT_G4` or `PDFR_COMPRESSION_JPEG`
HorizontalDPI, VerticalDPI	Positive pixel resolutions
Rotation	0, 90, 180 or 270

Return value

The one-based page number on success, or 0 on failure

Remarks

The method preserves ownership of InStream, resets its position to zero and otherwise applies the same validation and direct-embedding rules as AddPDFRRasterPageFromString
