Converting to Flashpix Extensions (APP2)
The extended data recorded in APP2 marker segments can be converted readily to Flashpix extensions.
First of all, Figure 56 shows the conversion process when APP2 is recorded as one Interoperability per stream of
data.
An area with data size of 8000.H, Default value 00.H is allocated to the stream name "/¥005MyPropertySet" (¥005
means 005.H) in the Flashpix file Structured Storage structure, and the stream data recorded in APP2-2 is copied
to offset 00000000.H, that is, the start of the allocated area.

Figure 56 Conversion to Flashpix Extensions (1)
Next, Figure 57 shows the conversion process when one Interoperability per two streams of data is recorded in
APP2.
This time an area with data size of 10000.H, Default value 00.H is allocated to the stream name
"/¥005MyPropertySet" in the Flashpix file Structured Storage structure, and the stream data recorded in APP2-2 is
copied to offset 00000000.H, that is, the start of the allocated area, while the stream data recorded in APP2-3 is
copied starting from offset 00008000.H.
