Notes on Conversion to Flashpix
The data recording method in this standard makes it possible to convert from Exif to Flashpix format with no loss of
image quality, and retaining all attribute information. A file that is thus designed from the start for conversion to
Flashpix is called a Flashpix-Ready (FPXR) file.
There are three main Flashpix-Ready functions:
g) All Exif tag information is mapped to the Flashpix Image Info Property Set,
h) APP2 extended data can be converted to Flashpix extensions,
i)
JPEG images can be converted to the Flashpix tile structure without image quality loss, making use of restart
markers.
Figure 53 illustrates the conversion process.
