# 1. Picasa Section | |
# | |
# The picasa section contains album-related metadata. | |
# Obviously, it is only present if the image folder was | |
# converted to a picasa album or if it was created during | |
# an import of images from a digital camera. | |
#--------------------------------------------------------- | |
[Picasa] | |
# the name of the album | |
name=Foo Bar birthday | |
# category: "Folders on Disk" for local albums | |
category=Folders on Disk | |
#if album was downloaded from picasa web albums, a key in this format | |
# is stored | |
P2category=Downloaded Albums~otheruserid | |
#if the album was uploaded, the username and album id are referenced in this format: <picasa user name>_lh=<picasa web album id> | |
joedoe_lh=5620038667642797505 | |
#------------------------------------------------------------- | |
# 2. Contacts Section | |
# | |
# the contacts section matches the recognized faces of | |
# persons to the contacts of the picasa user. | |
# format <person_id>=<picasa user name>_lh,<picasa contact id> | |
# TODO: what about not-yet confirmed or unidentified faces | |

# 3. Photo Entries | |
# | |
# each photo found in the current directory gets one ini section | |
# in the file, named after its filename. depending on the file | |
# type (jpeg vs camera raw), different metadata is stored in the | |
# section. | |

# 3.2 FILTER SETTINGS | |
# all applied filters per photo are recorded to .picasa.ini | |
# to provide an editing history and/or an easier undo facility. | |
# Basic filter key format: | |
# the filters key of each photo stores a semicolon-separated list of filter entries: | |
filters=enhance=1;crop64=1,45930000ba03defe; | |
# each entry follows the format | |
# <filter identifier>=1,<filter value 1>,<filter value 2>,<..filter value n>; | |
# Here is a list of valid filter identifiers | |

# APPENDIX | |
# | |
# A.1 DATA TYPES | |
# A.1.1 CROP BOX RECTANGLES (*) | |
# Picasa uses a special string format to store crop boxes of | |
# detected faces and from an applied crop filters. The number encased | |
# in the rect64() statement is a 64 bit hexadecimal number: | |
# rect64(3f845bcb59418507) | |
# break this number into 4 16-bit numbers by using substrings: | |
# '3f845bcb59418507'.substring(0,4) //"3f84" | |
# '3f845bcb59418507'.substring(4,8) //"5bcb" | |
# '3f845bcb59418507'.substring(8,12) // "5941" | |
# '3f845bcb59418507'.substring(12,16) // "8507" | |
# convert each obtained substring to an integer and divide it | |
# by the highest 16-bit number (2^16 = 65536), which should give 0 < results < 1. | |
# these are the relative coordinates of the crop rectangle (left,top,right,bottom): | |
# parseInt("3f84",16)/65536 //0.24810791015625 - left | |
# parseInt("5bcb",16)/65536 //0.3585662841796875 - top | |
# parseInt("5941",16)/65536 //0.3486480712890625 - right | |
# parseInt("8507",16)/65536 //0.5196380615234375 - bottom | |
# for absolute coordinates, multiply the left/right coordinates with | |
# the image width and the top/bottom coordinates with the image height | |
# A.1.2 FRACTIONAL FLOATS (!) | |
# floats between 0 and 1 with a precision of 6 digits, e.g. 0.306743. | |
# Often used to encode relative settings or mouse positions. | |
# A.1.3 FLOATS (!!) | |
# arbitrary floats with a precision of 6 digits | |
# A.1.4. COLORS (#) | |
# colors are stored as 32-bit hex string, e.g. ff5bfff3 |
I think Contacts2 is version 2 of the Contact data.
I think 'redo' are commands that have been undone and can now be redone. I will add those to command stack.
I have not seen the link command. I wonder if they are active since they point to picasa web. Do those links work for you? I suspect I should ignore that field.
I can't figure out the moddate format, which I assume is modification date.
geotag looks like longitude/latitude
Can you post a photoid header? I have not seen that one.
I'm guessing width/height are just image info
I'm ignoring all the hash commands since I have no idea what they are.
I'm wondering about the encoding of these files. Is it UTF-8?
@Philipp91 In English language Windows, .picasa.ini files are encoded in UTF-8
Other languages will probably need a different encoding to support the character set for the file names.
@SlimJimPoisson Thank you. I will use these as test cases. I appreciate you taking the time to do this.
