Intermediate images do not have a transparent background

[leoheck]

Only the final image has this transparent bg.

The default viewer shows this composition of images with the diff image in the center.

Using my own img-diff here to store temporary images does not have the new background, unfortunattely =/

Could you propagate this to the source image?

[leoheck]

Ah, a flag to keep the originals would be super good to have! I am using my own git-imgdiff just to save these files.

[leoheck]

This flag one could keep the originals too.

-k, --keep
by default, the svg diff files are deleted after launching the
viewer; this option lets the files in place after viewing them.

Oh, I already have an issue with this, #52

This change involves more rework than what I expected.

[leoheck]

My bad!

I am following your changes. It looks like you have to change a lot of files for every small feature. Is this something related to the OCaml itself or the features you are changing are not small as I was thinking.

[jnavila]

The span of changes is mostly due to the chain spanning from commandline argument to low level kicadlib stuff. It seems a lot of volume but it's not a big deal.

This one is more complicated, because the color scheme option is tied to the diffing process when it's internal. What the feature requests is a change in how the schematics are drawn, which is different. In fact, these should be two separated options.

Since this is pretty hard to implement I am going to close this issue now. This can be addressed externally in the git-imagediff script, for instance by just replacing the color in the generated images, directly.
