ImageIO.getPixelsize#
- ImageIO.getPixelsize(diff=1e-06)#
Return pixel size at the specimen level in nanometers.
For mrc files, it returns a single pixelsize if it’s the same for all dimensions, otherwise a list of pixelsizes for each dimension is returned. Pixelsizes are considered the same if they do not differ more than the specified difference.
- Parameters:
- difffloat, optional
The threshold for pixel size difference to be considered the same, by default 1e-6.
- Returns:
- float or list of float
Pixel size(s) in nm.
- Raises:
- ValueError
If the file format is neither ‘em’ nor ‘mrc’.
