cgsnapshot-->dialog_pickfile:Bad initial filename [message #90592]

I used the following code to extract my images as tif files

directory = 'C:\Users\Images'

file_mkdir, directory

write_tif, directory + '\' + name, tvrd ()

I overlaid a grid on the top of the images. When the images exported as tif files the grid was not red any more, it appears in white colour. To keep the colour of the grid I used the cgsnapshot instead

directory = 'C:\Users\Images'
void = cgsnapshot(/tif, filename= directory + '\' +name)

But I got the following system error

cgsnapshot-->dialog_pickfile:Bad initial filename: C:\Users\

Can anyone help with this?

Define the "name" variable.

Cheers,

I'm sure you *thought* you had, but the error message testifies
otherwise. :-)

Cheers,
