  I noticed that in online documentation (APIs -> Client APIs -> Remote object system -> Callback as function arguments) might have some outdated information. I was able to figure out, that app creates api function with signature sum: (a: int, b: int, success: (int) -> void, error: (int) -> void) -> void instead of sum: (callback: (int) -> void, a: int, b: int) -> void So in that case example would be POST /myobject/functions/sum HTTP/1.1 Host: localhost:2015 Client-ID: R4Nd0M Source-ID: 30 Content-Type: application/json Content-Length: 15 [1,2,314,315]

  @dantcamui This error generally means that the version of the engine that you have installed does not recognize some of the tools used in your app. Running it in the same (or newer) VisionAppster release as the one the app was created with should fix it.

  Yes, you can certainly use getPerspectiveTransform and warpPerspective functions if you know where the wanted corners are in the input image (like the corners of the credit card in your example.) It will work using either C or Python API. It all boils down to the question on how you can find the four corner points for the transform. Cheers, -- Keijo
