31.2.5.2 Understanding FrameMaker export filter limitations
On Windows systems, FrameMaker export filters use the GDI image, not the original graphic. The exported graphics are created by GDI rendering, regardless of the original DPI of the graphic. In effect, images are resampled to screen resolution (96 DPI) no matter what DPI you set, which can degrade image quality. Adjusting the DPI at which the resampling is done can help for vector graphics, but not for bitmap graphics. You can get more pixels, but they are interpolated from the 96 DPI rendition.
