No Pentax K20D Exif Makernotes
Hallo,
I work with a Pentax K20D Camera. The makernotes from exif data in jpeg's become not displayed.
I think it's a bug.

Hi Nutznieser,
It isn´t a bug.
XnView support makernotes only for a few brands (see WhatsNew.txt) and Pentax isn´t included.
For makernotes you can:
- use K20D Bundled software (Pentax Photo Browser)
- use ExifTool (http://www.sno.phy.queensu.ca/~phil/exiftool/) + ExifToolGUI (http://freeweb.siol.net/hrastni3/)

Maybe this perl library from Phil Harvey can shed some light on the shuttercount subject. Follow a parcial extraction:xnview wrote:Yes, i have a problem with it
Code: Select all
# Encrypt or decrypt Pentax ShutterCount (symmetrical encryption) - PH
# Inputs: 0) shutter count value, 1) ExifTool object ref
# Returns: Encrypted or decrypted ShutterCount
sub CryptShutterCount($$)
{
my ($val, $exifTool) = @_;
# Pentax Date and Time values are used in the encryption
return undef unless $$exifTool{PentaxDate} and $$exifTool{PentaxTime} and
length($$exifTool{PentaxDate})==4 and length($$exifTool{PentaxTime})>=3;
# get Date and Time as integers (after padding Time with a null byte)
my $date = unpack('N', $$exifTool{PentaxDate});
my $time = unpack('N', $$exifTool{PentaxTime} . "\0");
return $val ^ $date ^ (0xffffffff - $time);
}

Hallo,
I have to say thankyou for implemented the makernotes for Pentax K20D!
But one value is still allways bad: The field shutter count.
Could you repair that? It would be perfect!

EXIF in XnView will not show shutter count for Pentax istDL. Shutter counts for Nikon D 50 and 70 display just fine. www.myshuttercount.com will display Pentax shutter count after you upload a photo. That's probably good enough for government work.
