Step 3: Export to PDF - MRC

PDF Standard Keys – PDF MRC Standard Keys

Note: If you would like to tune PDF Mixed Raster Content parameters manually, please use the following order of MRC keys in your CLI command:

if needed, specify MRC compression level using -pmcl key;
specify other MRC keys.

--pdfMrcMRCEnabled

This key specifies whether tuning Mixed Raster Content (MRC) parameters is enabled. By default, MRC is disabled.

Key	Parameters	Default
-pmrc	no
-pmrc	–pdfMrcMRCEnabled

--pdfMrcBackgroundColor

This key specifies the background color. You can use -pmbc key with original parameter. In this case, the background color will be detected automatically based on the original background. By default the background color is white or RGB(255,255,255).

Key	Parameters	Default
-pmbc	lor in RGB format or original string parameter	0xffffff
-pmbc	–pdfMrcBackgroundColor

--pdfMrcBackgroundDownSampling

This key specifies the down sampling rate of the background. Only a positive rate makes sense.

Key	Parameters	Default
-pmbds	background down sampling rate	4
-pmbds	–pdfMrcBackgroundDownSampling

--pdfMrcBackgroundFormat

This key specifies the background format.

Key	Parameters	Default
-pmbf	JpegColor, JpegGray (see descriptions in ExportPictureFormatEnum)	JpegColor
-pmbf	–pdfMrcBackgroundFormat

--pdfMrcBackgroundQuality

This key specifies the value of JPEG compression for background color in percentage points.

Key	Parameters	Default
-pmbq	background JPEG quality in percent	5
-pmbq	–pdfMrcBackgroundQuality

--pdfMrcColorMaskDownSampling

This key specifies the down sampling rate of the color mask. Only a positive rate makes sense.

Key	Parameters	Default
-pmcmds	color mask down sampling rate	4
-pmcmds	–pdfMrcColorMaskDownSampling

--pdfMrcColorMaskFormat

This key specifies the color mask format.

Key	Parameters	Default
-pmcmf	JpegColor JpegGray ZipColor (see descriptions in ExportPictureFormatEnum)	ZipColor
-pmcmf	–pdfMrcColorMaskFormat

--pdfMrcColorMaskQuality

This key specifies the color mask JPEG quality in percentage points. The bigger the value, the better the quality.

Key	Parameters	Default
-pmcmq	color mask JPEG quality in percent	30
-pmcmq	–pdfMrcColorMaskQuality

--pdfMrcCompressionLevel

This key specifies the MRC compression level.

Key	Parameters	Default
-pmcl	LowCompression AvgCompression MaxCompression Custom (see descriptions in PDFMRCCompressionLevelEnum)	AvgCompression
-pmcl	–pdfMrcCompressionLevel

--pdfMrcDoNotKeepBackground

This key specifies not to keep the original background during export to PDF/A. If -pmnkb key is not used, the original background is retained.

Key	Parameters	Default
-pmnkb	no
-pmnkb	–pdfMrcDoNotKeepBackground

--pdfMrcNotMonochromeText

When this key is not used, the recognized text is monochrome. Also if you do not use -pmnmt key, you can specify the text color using -pmtc key.

Key	Parameters	Default
-pmnmt	no
-pmnmt	–pdfMrcNotMonochromeText

--pdfMrcPicturesInBackground

This key specifies whether pictures should be considered as parts of the background. If you use -pmpib key, the background compression options are used for the pictures. When you do not use this key, pictures are not considered as parts of the background.

Key	Parameters	Default
-pmpib	no
-pmpib	–pdfMrcPicturesInBackground

--pdfMrcTextColor

This key specifies the text color in monochrome mode, i.e., only when -pmnmt key is not used. By default, the text color is black or RGB(0,0,0).

Key	Parameters	Default
-pmtc	color in RGB format	0x000000
-pmtc	–pdfMrcTextColor

--pdfMrcTextMaskDownSampling

This key specifies the down sampling rate of the text mask. Only a positive rate makes sense.

Key	Parameters	Default
-pmtmds	text mask down sampling rate
-pmtmds	–pdfMrcTextMaskDownSampling

--pdfMrcTextMaskFormat

This key specifies the text mask compression algorithm.

Key	Parameters	Default
-pmtmf	CCITT4 JBIG2 (see descriptions in ExportPictureFormatEnum)	JBIG2
-pmtmf	–pdfMrcTextMaskFormat

--pdfMrcTextMaskQuality

This key specifies the text mask quality in percentage points. The bigger the value, the better the quality.

Key	Parameters	Default
-pmtmq	text mask JPEG quality in percent	75
-pmtmq	–pdfMrcTextMaskQuality
