Cropping tool

At the moment (unless I am missing something!) when you want to crop you need to draw the box around the cropping area. That doesn't allow fine adjustment and can also make very fine cropping almost impossible. 

I'd like to see that the box size can be changed on each line independently and that you can also use this on a zoomed in version. That way if you want to crop as little as possible you can be very precise and accurate with your cropping tool.

Hi Sara,

Currently there are 2 ways to make crops:

  1. drawing crops
  2. providing offsets for all borders, the number you enter are pixels. With positive values, you crop, with negative values you uncrop.

Making the crops while being zoomed in or making fine adjustments using values that are shown would be something for my RFC list. I'll write it down.

In cases where I needed very fine cropping, I usally cropped a previously cropped image. So I would use it iteratively.

@ancalime Gideon, a little more info would be appreciated. What version of APP are you using? How are you trying to crop images?

Version 1.082 and I am trying to crop in tab nr 9. Draw box, press crop image, save image, and see that image has not changed (stacking artifacts are still there)

@ancalime The cropped and saved file has a slightly different name than the original. Do the sizes of the two files differ? A very obvious question but I have to ask it: is the file saved in the directory where you expect it to be saved or perhaps in a different one? Please check the working directory and make sure it is there.

It is.... I seemingly have to click on the picture itself down below in the list. I thought that went automagically. It works. Thanks for the pointer! I also figured out the debayering process. Files show as GBRG, whilst camera is RGGB. Selecting RGGB in Tab 0 and force CFA did the trick. No idea why the fits indicate GBRG. Lekker prutsen, dan kom je er wel 😉 Thanks Wouter
