Hi there,
I'm trying to work with some edits spherical still photography and uploading to Google Street View and Facebook (now that Facebook supports 360 images). Running into a small issue because of editing software I use (Snapseed) removes some of the meta data related to the image being a spherical image (in particular, GPANO tags). Without these tags in place, Google Street View and Facebook don't recognize the images as 360/spherical images (and either reject the image or just post as a regular image).
Right now, my only work-around relies on Photoshop. Using Photoshop, I have to export the .XMP from the original image and then import that .XMP file into the edited version of the image (and I need to select "Clear existing properties and replace with template properties"). Then, when I upload the edited image, it's recognized as a spherical image.
I was hoping to use exiftool to automate this process (and not need Photoshop).
Basically, I want to wipe the meta data from the destination and replace it with the source's data. This is what I tried...
exiftool -all= -tagsfromfile original.JPG -all:all destination.JPG
But, when I do this, not all of the tags in the source are copied to the destination? For example, this is the relevant data that I need to copy (from the original JPG):
<GPano:ExposureLockUsed>False</GPano:ExposureLockUsed>
<GPano:StitchingSoftware>Street View - 2.3.0</GPano:StitchingSoftware>
<GPano:CaptureSoftware>Street View - 2.3.0</GPano:CaptureSoftware>
<GPano:CroppedAreaLeftPixels>0</GPano:CroppedAreaLeftPixels>
<GPano:CroppedAreaTopPixels>392.3809523809524</GPano:CroppedAreaTopPixels>
<GPano:CroppedAreaImageWidthPixels>5120</GPano:CroppedAreaImageWidthPixels>
<GPano:CroppedAreaImageHeightPixels>1768.571428571428</GPano:CroppedAreaImageHeightPixels>
<GPano:FullPanoWidthPixels>5120</GPano:FullPanoWidthPixels>
<GPano:FullPanoHeightPixels>2560</GPano:FullPanoHeightPixels>
<GPano:ProjectionType>equirectangular</GPano:ProjectionType>
<GPano:UsePanoramaViewer>True</GPano:UsePanoramaViewer>
<GPano:PoseHeadingDegrees>194</GPano:PoseHeadingDegrees>
<GPano:FirstPhotoDate>2016:07:27 13:52:55-04:00</GPano:FirstPhotoDate>
<GPano:LastPhotoDate>2016:07:27 13:54:24-04:00</GPano:LastPhotoDate>
<GPano:SourcePhotosCount>34</GPano:SourcePhotosCount>
But, after running the above command, the meta data in the destination looks like this:
<GPano:CaptureSoftware>Street View - 2.3.0</GPano:CaptureSoftware>
<GPano:CroppedAreaImageWidthPixels>5120</GPano:CroppedAreaImageWidthPixels>
<GPano:CroppedAreaLeftPixels>0</GPano:CroppedAreaLeftPixels>
<GPano:ExposureLockUsed>False</GPano:ExposureLockUsed>
<GPano:FirstPhotoDate>2016-07-27T13:52:55</GPano:FirstPhotoDate>
<GPano:FullPanoHeightPixels>2560</GPano:FullPanoHeightPixels>
<GPano:FullPanoWidthPixels>5120</GPano:FullPanoWidthPixels>
<GPano:LastPhotoDate>2016-07-27T13:54:24</GPano:LastPhotoDate>
<GPano:PoseHeadingDegrees>194</GPano:PoseHeadingDegrees>
<GPano:ProjectionType>equirectangular</GPano:ProjectionType>
<GPano:SourcePhotosCount>34</GPano:SourcePhotosCount>
<GPano:StitchingSoftware>Street View - 2.3.0</GPano:StitchingSoftware>
<GPano:UsePanoramaViewer>True</GPano:UsePanoramaViewer>
For some reason, the following two tags aren't being copied...
<GPano:CroppedAreaTopPixels>392.3809523809524</GPano:CroppedAreaTopPixels>
<GPano:CroppedAreaImageHeightPixels>1768.571428571428</GPano:CroppedAreaImageHeightPixels>
Without these two tags, the upload fails. If I manually insert this data into the destination, the upload succeeds.
Any ideas as to why these two tags aren't been copied from the original to the destination?
Thanks,
Kristin.
Hi Kristin,
This is because ExifTool expects an "integer" value for these tags. You will see warnings like this if you add the -v3 option:
Not an integer for XMP-GPano:CroppedAreaTopPixels
I will change this to support "real" values in the next release (10.25), but until then you may be able to work around the problem by copying the XMP as a block. This will overwrite all XMP in the target image, but will copy all XMP verbatim from the source image:
exiftool -tagsfromfile original.JPG -xmp destination.JPG

Ah, makes sense. And thanks—copying the block totally worked! Thanks!
