| # 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>; | |

| # 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.
