After years of functioning faultlessly I suddenly have a problem with a Pano X database and I am not able to detect the reason why. Maybe other eyes will see something I don’t.
Basics: Mac Mini (Mid 2011), OSX 10.13.6 (the last one this model accepts).
My database is for photos with the pertinent technical and subject data and each record contains a jpg of the photo. Each record is about only one photo, which has a unique number distinguishing it from others. This unique number consists of:
TP (Type or Format) = is empty in the case of 35mm film
R-NO (Archive number) = consecutive number given to each exposure
ES = error correction number (in the case of erroneous R-Nos). Empty when no error.
.YR = last 2 digits of the year when shot was taken
The unique number thus consists of: +TP+«R-NO»+ES+YR in 4 separate fields
This database is set up new for every calendar year resulting in a few hundred to several thousand records each. A folder
YYYY thumbs ƒ
holding the jpgs is accompanying every Pano X database. This whole package is within a yearly folder
Photo. YY ƒ .
Now to my problem:
In the folder Photo.71 ƒ there are 2 consecutive records 747.71 and 748.71 with the same subject (a chapel) taken within a few minutes from each other. When clicked on they came up with their respective jpgs with no problem at all.
Then, I decided to put a slightly larger scan into the jpg folder. This also worked without problems in all cases but for these 2 records: 747.71 shows the bigger jpg, 748.71 doesn’t show any image at all.
The procedure to call up the image is:
In the “BigPix” view of the record in Data Mode clicking on the image area to activate it, there is the following formula:
“1971 thumbs ƒ/”+TP+«R-NO»+ES+YR
This brings up the jpg scan in the record 747.71 and nothing at all in the record 748.71. As you will see the “fishing” formula doesn’t have the particular record’s number but grabs the pertinent parts of the unique number (see above) when the record is open.
This has me totally baffled, I can not find an explanation. Anybody to give it a try?
