Dialog Box: PDF
This dialog box allows you to specify PDF format settings.
Here you can select the standard to be used for the output file:
Here you can select the version of PDF to be used for the output file (1.3, 1.4, 1.5, 1.6, 1.7, 2.0). Select Auto if you want the program to make the choice for you.
Note. All items other than Auto specify the latest possible version of the PDF format. So if, for example, you select version 1.6, the output file will be saved in the earliest version of the format that supports all features of the document, but this version will not be later than 1.6.
Use this slider to select one of the three available image saving modes for PDF documents.
After selecting a suitable image saving mode, you can fine-tune individual image saving settings manually. Changing the saving mode again will reset these settings.
|Enhanced compression (MRC)
If this option is selected, images will be compressed using Mixed Raster Content (MRC) compression, which works better for some images than the commonly used JPEG compression method. For instance, MRC works better on good quality images with high-contrast text printed on a uniform background. Use MRC compression to produce smaller PDF files. The following MRC modes are available:
Note. Enabling MRC for low-contrast images and images with multi-colored backgrounds may result in undesirable artifacts.

Note. If you set this value to -300 dpi, the resolution of all pictures exceeding 300 dpi will be reduced to 300 dpi.
