wrong error message?

[paolobenve]

I have a python app that uses GExiv2 to add gps info to the images.

It modifies the image with teself.exif.set_gps_info(self.longitude, self.latitude, self.altitude)

self.exif[IPTC + 'City'] = self.names[0] or ''
self.exif[IPTC + 'ProvinceState'] = self.names[1] or ''
self.exif[IPTC + 'CountryName'] = self.names[2] or ''
self.exif['Iptc.Envelope.CharacterSet'] = '\x1b%G'

then it saves the file.

When trying to write a CR3 raw image I get the error "Setting Image comment in BMFF images is not supported".

However, the image hasn't any comment changed.

I'd expect a "Setting metadata in BMFF images is not supported" error message.

You are correct, the error message is wrong. Currently we are throwing a kerInvalidSettingForImage which has an error message of

exiv2/src/error.cpp

Line 51 in d2253c9

N_("Setting %1 in %2 images is not supported"), // kerInvalidSettingForImage %1=metadata type, %2=image format

Instead this should be a kerWritingImageFormatUnsupported id which has an error message of

exiv2/src/error.cpp

Line 50 in d2253c9

N_("Writing to %1 images is not supported"), // kerWritingImageFormatUnsupported %1=image format

I will try and find time during the week to work on this. Once the fix for the main branch has been merged, I will add it to the 0.27-maintenance branch and then this issue can close.

Thanks for reporting this.
