I have a problem where I’m not able to load my RAW-file for generating a multispectral image.

The RAW-file is a .CR3 from a Canon R5.

I use a Macbook Air M2 (2022); OS: Sonoma 14.2.1

ImageJ is 1.54g; and the one made for the ARM Mac’s.

I have no problems with using the test images: “Rudbekia Flower Sample”, but the .CR3 file will not load when promted to choose the file.

The following windows pop op after it tries to load the file:

1st small window “No image”:

There are no images open in line 63

run (”32-bit” <)> ;

2nd small window “No image”:

There are no images open in line 367

photoID = getImageID ( <)> ;

3rd larger window “Exception”:

ImageJ 1.54g; Java 13.0.6 [64-bit]; Mac OS X 14.2.1; 275MB of 3000MB (9%)

Macro line number: 55

java.lang.NegativeArraySizeException: -256945280
