The following options determine how image files are converted
to PDF. For instructions about accessing these settings, see Create or edit file type settings.
- Filename Extensions:
- Comma-separated list of filename extensions that can be converted.
- Try Fallback Converter:
- PDF Generator can use either Java™ or
Acrobat to convert image files to PDF. When this option is selected
and a conversion fails or reaches the specified time-out limit,
PDF Generator attempts the conversion by using the alternate method.
If alternate method fails or reaches the specified time-out limit,
an exception is written to the log file.
Note: JPEG
2000 files can only be converted using Acrobat.
- Use OCR:
- Specifies whether to apply OCR (optical character recognition)
to the PDF. OCR software enables you to search, correct, and copy
the text in the PDF.
Note: The OCR PDF (searchable PDF) feature
is supported only on Microsoft Windows.
- Primary OCR Language:
- Specifies the language for the OCR engine to use to identify
the characters.
- PDF Output Style:
- Determines the type of PDF to produce. All formats apply OCR
and font and page recognition to the text images and convert them
to normal text.
- Searchable Image:
- Ensures that text is searchable and selectable. This option keeps
the original image, deskews it as needed, and places an invisible
text layer over it. The Downsample Images option determines whether
the image is downsampled and to what extent.
- Searchable Image (Exact):
- Ensures that text is searchable and selectable. This option
keeps the original image and places an invisible text layer over
it. Recommended for cases that require maximum fidelity to the original
image.
- ClearScan:
- Synthesizes a new Type 3 font that closely approximates the original,
and preserves the page background by using a low-resolution copy.
- Downsample Images:
- Decreases the number of pixels in color, grayscale, and monochrome
images after OCR is complete. Choose the degree of downsampling
to apply. Higher-numbered options do less downsampling, which produces
higher-resolution PDFs.
