Xnconvert bug and feature

[nonwo]

Leave this with bug and features at evaluation for excellent xnconvert and xnview


Xnconvert v1.51 "bug"

When use action IPTC/XMP and enabled option is "Keep and add new value ...." (with replace all values disabled), when modify a single field almost all other fields are erased.

Made 2 tests with option set "Keep and add new value ...." and mode used is IPTC only

1) Photos have many Iptc fields written, whit Xnconvert change only City name (leaving all other fields blank), then all fields are erased except object name.

2) Photos have many iptc fields written, with xnconvert change only "original transmission reference", then all other iptc fields are erased except object name.


Xnconvert suggestions

* in action TEXT, in Fill will be useful option for customize fill size with selection width and height that exceed the edges of the text. maybe also fill feature for use texture/picture
* in Text, when insert IPTC tags option for write text in Uppercase
* option for erase/blank selected iptc/xmp fields, leaving others untouched
* batch edit exif (similar to xmp-iptc) using exiftool
* when work in batch mode and want overwrite all files with same name from dialog can be useful option "Yes to All"
* xnconvert/xnview: support read/write/preserve exif/iptc/xmp tags in jpeg xr/hd photo and .png formats using exiftool that support this
* option in crop for select automatic crop in various AR 4:3 3:2 16:9 16:10 ...
* in borders option for preserve original aspect ratio (proportional margins), using different size for vertical and horizontal (auto-adapted) and/or option for write borders inside picture
* feature for tag video files for formats like avi mkv mp4 ogg mov vob mpg ..

Xnview maybe bug

when save photo to jpeg xr using Z...r 14 and file is saved with embedded Xmp tags, if file is saved with extension .jxr or .wdp xnview do not open it, but if the same file is renamed with extension .hdp xnview open it (but not read xmp embedded tags)
