About File Types
Images scanned with CapturePerfect can be saved as TIFF (*.tif), BMP (*.bmp), JPEG (*.jpg) or PDF (*.pdf)
files. However, please note that the JPEG file type can be selected only when the specified scanning mode
is 256-level Gray, 24-bit Color, or Auto Color Detection.
Note
The available scanning modes will differ depending on the scanner.
When the file type is JPEG File (*.jpg), the image quality set by the JPEG File setting in the Option menu
is applied. Refer to Setting JPEG File Image Quality

and white images are saved as TIFF files using CCITT Group 4 compression, regardless of the current
TIFF file compression settings in the Options menu. Color images are saved as JPEG files using the
JPEG file image quality settings in the Options menu.
When the file type is PDF File (*.pdf), the compression ratio set by the PDF File setting in the Options
menu is applied. Refer to Setting PDF File Saving Options
(P. 21) for details.
