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 | |
| –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 |
| –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 |
| –pdfMrcBackgroundDownSampling | ||
--pdfMrcBackgroundFormat
-
This key specifies the background format.
| Key | Parameters | Default |
|---|---|---|
| -pmbf | JpegColor, JpegGray (see descriptions in ExportPictureFormatEnum) |
JpegColor |
| –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 |
| –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 |
| –pdfMrcColorMaskDownSampling | ||
--pdfMrcColorMaskFormat
-
This key specifies the color mask format.
| Key | Parameters | Default |
|---|---|---|
| -pmcmf | JpegColor JpegGray ZipColor (see descriptions in ExportPictureFormatEnum) |
ZipColor |
| –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 |
| –pdfMrcColorMaskQuality | ||
--pdfMrcCompressionLevel
-
This key specifies the MRC compression level.
| Key | Parameters | Default |
|---|---|---|
| -pmcl | LowCompression AvgCompression MaxCompression Custom (see descriptions in PDFMRCCompressionLevelEnum) |
AvgCompression |
| –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 | |
| –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 | |
| –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 | |
| –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 |
| –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 | |
| –pdfMrcTextMaskDownSampling | ||
--pdfMrcTextMaskFormat
-
This key specifies the text mask compression algorithm.
| Key | Parameters | Default |
|---|---|---|
| -pmtmf | CCITT4 JBIG2 (see descriptions in ExportPictureFormatEnum) |
JBIG2 |
| –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 |
| –pdfMrcTextMaskQuality | ||
