Automatically rotates pages according to the direction of text.
Auto-Rotate Pages
• Rotates all pages to match the orientation of the majority of text in the document.
Collectively By File
• Rotates each page based on the orientation of the text on that page.
Individually
• Prevents pages from rotating.

Note: If Process DSC Comments is selected in the Advanced panel and if %%Viewing Orientation comments are
included, these comments take precedence in determining page orientation.
Specifies whether to display a PDF with left-side or right-side binding. The Binding setting affects the

display of pages in the Two-Up Continuous view and the display of thumbnails side by side.
Use for PostScript files to emulate resolutions based on the printer they are printing to. Permitted values
Resolution
range from 72 to 4000. Use the default setting unless you plan to print the PDF on a specific printer while emulating
the resolution defined in the original PostScript file.
Note: Increasing the resolution setting increases file size and may slightly increase the time required to process some files.
Specifies which pages to convert to PDF.

Images panel options
The options in the Images panel specify compression and resampling for color, grayscale, and monochrome images.
You may want to experiment with these options to find an appropriate balance between file size and image quality.
The resolution setting for color and grayscale images should be 1.5 to 2 times the line screen ruling at which the file
will be printed. The resolution for monochrome images should be the same as the output device, but be aware that
saving a monochrome image at a resolution higher than 1500 dpi increases the file size without noticeably improving
image quality. Images that will be magnified, such as maps, may require higher resolutions.
Note: Resampling monochrome images can have unexpected viewing results, such as no image display. If this happens,
turn off resampling and convert the file again. This problem is most likely to occur with subsampling, and least likely
with bicubic downsampling.
The following table shows common types of printers and their resolution measured in dpi, their default screen ruling
measured in lines per inch (lpi), and a resampling resolution for images measured in pixels per inch (ppi). For
example, if you were printing to a 600-dpi laser printer, you would enter 170 for the resolution at which to resample
images.
