Image Quality and Processing
If ePublisher cannot use an original image in the output, or if ePublisher determines it needs to modify the image based on how it is included in the source document, ePublisher rasterizes the image using the options you define for your graphic styles in Style Designer. For example, you can define the dots per inch (DPI) and format for the final images. Rasterization of an image can cause the image to be blurry or distorted in the output.
For more information and specific considerations about your images, see “Image Formats and Considerations in FrameMaker” and “Image Styles and Considerations in Word”.
