can I set numeric value to variable?

[Sahar Vilan]

Hello,

I'm new to ImageJ and I try to write a simple macro to open raw image.

It works with fixed values (1) but not with variables (2).

1)       run("Raw...", "(open image=[16-bit Unsigned] width=3072 height=3072
offset=0 number=1 gap=0 little-endian");
         OK!

2)       w = 3072;
run("Raw...", "(open image=[16-bit Unsigned] width=w height=3072 offset=0
number=1 gap=0 little-endian");
         ERROR!

Can anyone help me with this?

Thanks,
Sahar Vilan

Hello Sahar,

You have to break the string with this concatenation syntax

"string" -> "st"+variable+"ring

will put the contents of 'variable' between "st" and "ring".

 > 2)       w = 3072;
 > run("Raw...", "(open image=[16-bit Unsigned] width="+w+" height=3072
offset=0


The new string is then passed to the function.
