Bug: Maps Editor, Changing Scale

[Jordan-Pierce]

There was a request to change scales of a map after making segmentations. I see that the option to edit is there, however, there was a crash in RasterOps.py in the function update; essentially a field (that doesn't exist in some cases) was trying to be accessed. I just added that None be a default value, and skip if None. This works in the next loop, as if value is None it's already skipped:

    def update(self, ann, scale_factor):

        self.clear()

        self.ann = ann

        if type(ann) == Blob:
            for field in self.fields:
                value = getattr(ann, field)
                if field == 'area':
                    value = round(value * (scale_factor) * (scale_factor) / 100, 2)
                if field ==  'surface_area':
                    value = round(value * (scale_factor) * (scale_factor) / 100, 2)
                if field ==  'perimeter':
                    value = round(value * scale_factor / 10, 1)
                if type(value) == float or type(value) == np.float64 or type(value) == np.float32:
                    value = "{:6.1f}".format(value)
                if type(value) == int:
                    value = str(value)

                self.fields[field].setText(value)
        else:
            for field in self.fields:

                value = ""
                if field == 'id' or field == 'class_name' or field == "note":
                    # Returns None instead of Error
                    value = getattr(ann, field, None) # <------ Added
                    # If None, skips (see below)
                    if value is None: # <-------- Added
                        continue
                    if type(value) == int:
                        value = str(value)

                self.fields[field].setText(value)


        for input, attribute in zip(self.attributes, self.region_attributes.data):
            key = attribute['name']
            if not key in ann.data:
                continue
            value = ann.data[key]
            if value is None:   # <-------------- Already here
                continue;
            if attribute['type'] == 'string':
                input.setText(value)
            elif attribute['type'] == 'integer number':
                 input.setValue(value)
            elif attribute['type'] == 'decimal number':
                input.setValue(value)
            # elif attribute['type'] == 'boolean':
            #      input.setChecked(value)
            elif attribute['type'] == 'keyword':
                input.setCurrentText(value)

Lemme know if this might mess with something downstream somewhere.
