Change units (in, px, mm, cm) permanently
Is it possible to change units (in, px, mm, cm) permanently for all images?

The dimensions displayed in the crop tool will depend on the units chosen in the crop tool. So if you choose the crop tool you will see size. You can choose the units as px, in, mm, or cm. BUT they will also depend on the options chosen in the active process recipe. So for instance I have an image that shows as 5568x3712 px. If I change the units to inches, to shows as 18.56 x 12.37, because my process recipe specifies a resolution of 300px per inch. (18.56 x 300 = 5568). If I change the resolution in the process recipe to 200 px per inch, the crop tool now shows the size as 27.84 x 18.56 inches (because 27.84 inches x 200 px per inc = 5568 pixels).

Edited to add: here's another complication. I have other recipes that specify a size in pixels. For example I have a recipe that produces JPGs with 1600 px on the longest side (for putting online). If that is the active recipe, I can't change the units in the crop tool to anything apart from pixels.0 -

Thanks for your reply. So I gather it isn't possible to once and for all select, say, pixels as the overall unit for all images.0 -
Hi Thomas,
When you select the crop tool, you have the choice of the unit. I have chosen "pixels" once for all, and every time I use the crop tool, I get units in pixels, provided you select "unconstrained" in the Ratio field of the crop tool, and provided the scale field in the process recipe (basic) is selected as "fixed".

Hi Robert,
Thanks for the reply. So this this would only work with "unconstrained"?

No Thomas, this is my choice, but it certainly works with others. 0 -
But if I have a recipe that is intended for a print that is, for example, 8x10 inches, and set the crop ratio to Output, I will still see the dimensions of the crop displayed in inches.

Right !! I never use the output recipes for direct printing, actually, that's why...0 -

No neither do I. But I might use such a recipe to create a file to be printed for example by a print lab.

I do something similar to Ian (apparently we stick together). I have a recipe that I normally have selected for when I'm working editing images - it has the minimum dpi I can tolerate for medium sized prints. That way when I'm cropping I can see the dimensions in inches as I crop and make sure I don't crop things too much to be printed later (or at least know when I am creating an image that will be online only 😊 . That recipe is not one I actually use for any real output - its just the one I use by default so I can see the numbers I want to see in the crop too. 0 -

Good idea !! I'll do it, but in cm rather than in inches 😄0 -

Glad you found it helpful. Yeah I'd rather in in cm too and officially Canada is metric but there is just no getting totally away from the imperial system here especially when buying lumber and photographic prints. 😄thomaskyhn wrote:

Welcome - someone else mentioned it here or I read about it on a blog post I cannot remember who to credit with it but it has proved very useful.0 -
Hi,
In my experience, when the crop tool is selected, the displayed dimensions get the unit of the process recipe selected (C1 20 13.1.1)
I don't know if it's documented, but there is a trick to determine which unit is the unit of a particular recipe :
1 select the desired recipe in Process Recipes
2 Basic > Scale: choose Dimensions
3 choose the desired unit (cm)
4 Basic > Scale: choose the desired scale (Fixed)
And voilà. From now on, when the recipe is selected (not necessarily ticked), the dimensions are shown in centimeter0
