Hello

I am using ImageJ to add a scale bar to JPEG files taken with a digital
camera. These are 2048x1536 pix images that are rendered as 17.34 x 13 cm,
300 pix/in images (these data from Photoshop). When I apply a scale bar to
them in ImageJ and save them in Jpeg (at 100 quality) they become
2048x1536 pix images that are rendedreed at 72.25x54.19 cm, i.e. 72 pix
per inch (data also from Photoshop). This is problematic because they are
to go inserted as linked files in a Word document and when I update the
Word field to point to the new images with the scale bars they blow up.
Could anyone let me know if there is an easy fix for this? Is there a
global parameter that makes Imagej save the Jpegs at 300 pix/inch? Thanks
in advance

Manuel
