TransformMask.scaleNode assistance

I’ve been working on a quick demonstration of a mockup generator for Krita using 5.2. I can’t seem to get the TransformMask.scaleNode to actually scale the imported FileLayer. I’m hoping someone on here can point me in the right direction. I really like simplicity if possible.

The code is pasted below with a highlight on the line of code that doesn’t seem to be working at all…no errors, just doesn’t scale the transform mask.

from krita import *
import os
import time

def import_images_into_mockup(mockup_path, images_directory, output_directory):
    application = Krita.instance()
    currentDoc = application.activeDocument()
    currentLayer = currentDoc.activeNode()

    
    configParameters = InfoObject()
    configParameters.setProperties({
            'alpha': True,
            'compression': 1,
            'forceSRGB': True,
            'indexed': True,
            'interlaced': True,
            'saveSRGBProfile': False,
            'transparencyFillcolor': [255,255,255]
    })        

    # Loop through image files in the directory designated from the prompt
    for filename in os.listdir(images_directory):
        if filename.endswith(".png") or filename.endswith(".jpg"):
            image_path = os.path.join(images_directory, filename)

            # Create a new layer with the imported image but allow the mockup to be on top with transparent section
            scalingMethod = "none"
            new_layer = currentDoc.createFileLayer(filename, image_path,scalingMethod)
            root = currentDoc.rootNode()
            root.addChildNode(new_layer,currentDoc.nodeByName("Root"))
            
            # Create a transfrom mask to resize the image
            mask = currentDoc.createNode('Transform', 'transformmask')
            new_layer.addChildNode(mask, None)
            transform_mask = currentDoc.nodeByName("Transform")
            
            print(transform_mask.type())
            
            # Set the position and size of the new layer to match the mockup layer
            # ------------------PROBLEM LINE BELOW--------------------------
            transform_mask.scaleNode(QPoint(207,126),593,419,"Bicubic")

            # Export the mocked up image to the designated directory            
            output_name = output_directory + "/Mockup_" + filename 
            print(output_name)
            currentDoc.exportImage(output_name,configParameters)

            # Remove the image layer from the template to prepare for the next iteration
            new_layer.remove()


def main():
    # Ask the user for paths
    mockup_path = "C://Users//lv2sr//Documents//Home//ART//Mockups//Mockup Room1.kra"
    images_directory = QFileDialog.getExistingDirectory(None,"Select Image Directory", "*")
    output_directory = QFileDialog.getExistingDirectory(None,"Select Export Directory", "*")

    # Calls the function to import images into the mockup template
    import_images_into_mockup(mockup_path, images_directory, output_directory)

if __name__ == "__main__":
    main()

Transform Mask does not take scale Node. It uses toXML and fromXML

Thanks for the reply! In the meantime I circumvented the need for the transform mask by directly converting the file layer to a paint layer. however I did run into another hurdle…the currentDoc.setActiveNode seems to be anything but reliable in order to do the action conversion reliably. I may give the fromXML a shot with my original code above. So much for a quick demonstration…

If you want setActiveNode guarantees:
