0.85: No message box "...will lose all existing metadata"

Postby helmut » Sat Apr 15, 2017 2:05 pm

XnView: MP 0.85 - 64 bit
OS: Windows 10 - 64bit

When saving an image with meta data in a format that doesn't support meta data there is no warning message "Be careful, saving in this format will lose existing metadata!". The same happens when saving to a format that does support meta data but XnView doesn't support writing the metadata webp, JPG2000, and jxr.

Effect: Irritating behaviour

To reproduce:
1. Open a (JPG) image in XnView's viewer with EXIF meta data.
2. Save the image in PNG format.
Actual behaviour (bug): XnView saves the image. There is no warning that meta data is lost. :bug:

Expected behaviour: A message box (warning) with button to proceed or cancel is displayed.

I would vote for metadata support when converting to .flif and .webp.

Look, when you want to save your images in a format better (compressing) than .TIF or .PNG, in XnView/XnViewMP
you currently have no option to choose a format which preserves metadata.
And if you use another tool to create p.ex. WEBP with metadata, it is not shown in XnViewMP.
FLIF also supports metadata.

So if the libraries we are using in XnView/XnViewMP do not support metadata directly,
maybe a script with Exiftool (exiftool -tagsFromFile input.png output.flif) would do the job -
it can write tags to JP2, JXR, .PNG and FLIF;
writing to WEBP is currently not supported but WEBP itself supports metadata import.

O.k., thank you, I can also reproduce the problem. Issue 1205 is fixed in next version.

This problem is supposed to be fixed in XnView MP 0.87. Please check and confirm the bug fix here.
