Smaller problems with Edit Comment

[herb]

Hello Pierre,

(1)
XnViewMP has the feature to store some text in file descript.ion.
With menu Edit -> Edit Comment the "Edit Comment" window is opened. In field "description" the text has to be entered.
This info is displayed in "Information" window - Properties - File - Annotation.
I would like to propose to use identical words for this field.

And sometimes I found some unprintable characters at end of last line in this file.

(2)
In case of the field Comment (stored inside a *.jpg file) contains a NEWLINE (0x0A0D = \r\n) its value is displayed with 2 NEWLINE in "Edit Comment" window. I guess one for \r and one for \n

Thanks in advance
Herb

Annotation is best?

And sometimes I found some unprintable characters at end of last line in this file.

At the end of descript.ion?

NEWLINE was written by XnViewMP?

Hello Pierre,

sorry for my late reply.

(1)
In case of I see "unprintable" characters in file desript.ion they are stored at end of file - this means at end of last line of file descript.ion.

(2) ad annotation
In window "EditComment" the field is called: Embedded Comment
In Info panel - properties this embedded comment is shown as "annotation".

I stored the following in field Embedded Comment: <unicode-character> NEWLINE <unicode-character>.
In Info panel - properties annotation contains only <unicode-character>
In info panel - Exiftool displays the value properly -but with NEWLINE displayed as 1 dot.
- That NEWLINE is displayed as dot is an Exiftool feature.
- But because we have only 1 dot, it is clear that XnViewMP writes only LF (line-feed) or CR (carriage return).

In case the comment field inside th image contains LFCR as NEWLINE - which is default on Windows systems - XnViewMP shows 2 NEWLINE inside field EmbeddedComment.

Do we need an option to define whether XnViewMP writes NEWLINE as CR, as LF or as CRLF ?

I hope I have described all detailed enough.

Best regards

'Annotation' is best to use anywhere?

In case of I see "unprintable" characters in file desript.ion they are stored at end of file - this means at end of last line of file descript.ion.

how do you reproduce?

could you send me the file?

Hello Pierre,

First I want to wish you a Happy and Prosperous New Year 2020.
Then I have to say thanks for your great work on XnViewMP during 2019.

'Annotation' is best to use anywhere?

Exiftool calls this tag: -file:comment
So "Annotation" is also ok for me.

how do you reproduce?

I still try to find a golden rule how to reproduce.

could you send me the file?

Attached please find such a *.jpg-image as zip-file.

Hello Pierre,

I tried to find a way to reproduce the problem with "unprintable characters.

I started in a directory with 2 jpg images:
- file1: name contains only ascii characters
- file2: name contains ascii and also unicode characters (in my case some chinese characters)

(1) I assigned a description (annotation) to file1 with only 1 line and only ascii characters.
File descript.ion is written properly.
(2) I assigned a description to file2 with also chinese characters.
File descript.ion is NOT written properly: chinese characters are stored as ? This is also discussed in another post.
(3) I edited file description with a text-editor, wrote proper chinese characters - in filename itself and also in annotation -
and I stored the file in UTF-8 with BOM:
XnViewMP read this file properly when I tried to edit description/annotation again.
(4) I edited description with chinese characters: In detail I added another line and some more text.
NEWLINE was stored as \n by XnViewMP. And at lineend I found these unprintable characters.
(5) I removed the unprintable characters with my text-editor.
Now XnViewMP read this file not properly: the \n did not become a NEWLINE in description-field; it is shown as \n in printable form.

Hoping this helps
Best regards

Ok, i can reproduce. Not really a bug. By default, descript.ion file created is ANSI (for compatibility). If you create an empty unicode descript.ion file, it will be used.
