'''Pegasus PIC2''' (or whatever it's called) is a raster image format associated with some products from Pegasus Imaging Corporation. It is presumably the successor to [[Pegasus PIC]], which we'll refer to here as "PIC".

Like PIC, it is possibly a version of the format/technology named '''ePIC'''.

== Disambiguation ==
Not related to [[PIC2|Yanagisawa PIC2]].

See also the [[PIC]] disambiguation page.

== Format details ==
Like PIC, a portion of a PIC2 file resembles [[JPEG]] data. But PIC2 does ''not'' resemble [[BMP]] format.

While PIC uses the same fundamental compressed data format as standard JPEG, that's apparently not the case for PIC2.

Except for the first 4 and last 4 bytes, a PIC2 file seems to consist of a sequence of tagged segments. A segment consists of 1 byte for the segment type, then 4 bytes for the data size, then the data. Type 0 marks the end of the sequence.

Technical note: PIC2 apparently uses nonstandard JPEG segment type 0xb9 for its "SOF" segment.

== Identification ==
PIC2 files start with ASCII signature "{{magic|PIC2}}". The next byte might always be {{magic|0x01}}, the type of the first segment.

The string "{{magic|JPGE}}" appears somewhere near the beginning of the file, with byte {{magic|0x05}} appearing 5 bytes before it. In known files, it's observed to be at offset 22, but more than likely it's allowed to be somewhere else.

== Software ==
* Konica PC PictureShow v4 ([https://web.archive.org/web/20040213073356/http://www.konica.com:80/downloads/files/pcps4.exe pcps4.exe, archived]) reportedly supports the format
* PICPress probably supports it [{{DiscMasterURL|browse/29931/ibm3150-3159/ibm3157.tar/ibm3157/LXTPP383.ZIP}}]
* Possible decompression code: [https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/elsdec.c elsdec.c from FFmpeg]

(More research needed, to figure out what can decode PIC2.)
