Image scaling Macro

the finished page
Image scaling
with both images, available for corrections, if necessary

Very nice and useful.
I have done a short movie to illustrate the workflow:
Given the blueprint of a model create it again .. https://youtu.be/2iFE40uHrA8

Making the Image half transparent would be helpful ...

Good video!

Yes.
Also noted from your video that a "move to origin" function would be useful. You click on the point in the image that you want to be in the 3D-origin and its moved there.

It seems to me that the Image Workbench can be improved a lot with a number of useful but not too complicated tools.

Yes, indeed.

* Position markers/move to origin
* Change the transparency of images (its possible in open inventor)
* and cuted images

are interesting next steps.

The workbench is written in c++ so it's not as easily accessible as if it was coded in Python. The image importer seems to use alpha-cannel for the displayed image but it's not exposed to the user-interface so you need to change the c++ code to enable setting semi-transparent images if I understands how it works.

[microelly2]

Programming in C++ is to to time consuming for me.

I see two steps
First have a prototype in pyhton with one or more macros
Then finding somebody who will port it into c++ and intergrate it to the workbench

Or replace the workbench with python alltogether. I mean it only has two tools with very little functionlity, this could easily be done in python too, if someone is willing to put work into this.

This is probably the best solution

I registered on this forum simply to say thank you for this macro. I have to use reference drawings a lot and this will save me sooo much time. Well done.
