Demonstrates how to generate and save an image of a model.

Overview

In this example we create a View_ImageWriter object which allows us to generate and save an image of ModelData_Model .

Implementation

The main function will have the following structure:

• Read a model file and transfer its data to a ModelData_Model object:

aModel =  mtk.ModelData_Model()
 
# Reading the file
if not mtk.ModelData_ModelReader().Read(mtk.UTF16String(theSource), aModel):
    print("Failed to read the file " + theSource)
    return 1

• Create an View_ImageWriter and set some parameters:

aWriter = view.View_ImageWriter()
aWriterParameters = view.View_ImageWriterParameters()
 
# Set writer parameters
aWriterParameters.SetImageWidth(1200)
aWriterParameters.SetImageHeight(720)
aWriterParameters.SetViewIsFitAll(True)
aBackgroundColor = view.View_ColorBackgroundStyle(view.View_Color(255, 255, 255))
aWriterParameters.SetViewBackground(aBackgroundColor)
 
aWriter.SetParameters(aWriterParameters)

• Generate an image of a model and save it into a file:

# Generate the model image and save it into the file
if not aWriter.WriteFile(aModel, mtk.UTF16String(theDest)): 
    print("Failed to write the image file " + theDest)
    return 1
