Access image height/width beyond EXIF tags

[PanierAvide]

Hello,

First thanks for your work on this library, which is super useful and we use it extensively on Panoramax, especially on a little lib to read GPS and dates from JPEG images.

I'm wondering if there is a way to read image height/width from file itself when the dimensions are not available in EXIF tags (we used Exif.Photo.Pixel[X|Y]Dimension or Xmp.GPano.CroppedAreaImage[Height|Width]Pixels for now). In this image, not EXIF tags seem to contain this information : example.jpg.zip

Extracted EXIF & all tags:

{'Exif.Image.Make': 'GoPro',
'Exif.Image.Model': 'GoPro Max',
'Exif.Image.ExifTag': '78',
'Exif.Photo.DateTimeOriginal': '2024:09:29 17:10:00',
'Exif.Photo.OffsetTimeOriginal': '+00:00',
'Exif.Photo.SubSecTimeOriginal': '293000',
'Exif.Image.GPSTag': '150',
'Exif.GPSInfo.GPSLatitudeRef': 'N',
'Exif.GPSInfo.GPSLatitude': '49/1 11/1 548764799/10000000',
'Exif.GPSInfo.GPSLongitudeRef': 'W',
'Exif.GPSInfo.GPSLongitude': '0/1 21/1 325688400/10000000',
'Exif.GPSInfo.GPSAltitudeRef': '0',
'Exif.GPSInfo.GPSAltitude': '6330/100',
'Exif.GPSInfo.GPSTimeStamp': '17/1 10/1 293000/1000000',
'Exif.GPSInfo.GPSImgDirectionRef': 'T',
'Exif.GPSInfo.GPSImgDirection': '7766/100',
'Exif.GPSInfo.GPSDateStamp': '2024:09:29',
'Exif.Photo.UserComment': 'Lavc58.134.100'}

Exiftool manages to detect image size :

$ exiftool -G image.jpg
[ExifTool]      ExifTool Version Number         : 12.93
...
[File]          Image Width                     : 128
[File]          Image Height                    : 96
...
[Composite]     Image Size                      : 128x96
...

I have no idea if this is feasible with pyexiv2 😅 Thanks for your help 😀

Best regards

Hi!
I just released v2.15.0, which adds img.get_pixel_width() and img.get_pixel_height().
It is not recommended to get the width and height from the image metadata, as the metadata may be falsified.

Works like a charm, thanks for your fast implementation 😀
