[GR32] How to get image resolution

[Klaus01]

N'Abend,

is does not make any sense do put the resolution px/inch into the exif.
The resolution is depending on the device where the image will be displayed or printed.

The screen resolution is between 72 and 96px/inch.
A printer can have a resolution of 150,300 or 600 dots(px)/inch.

So an image with an width of 1000 pixels has width on the screen of round about 10 inches.
Printed it is physicaly much smaller.

Hope it helps.

Klaus
