Image Transparency Color in FireMonkey (FMX) with Python

Question

I know that the Image component support transparency in the FMX library with Python as long as the image has transparency built into the image, but what if you want to set a certain color to be the transparency color?

As an example. Let's say I have a PNG Image and I want all white ($FFFFFFFF) colors to be transparent, is this possible to do? If yes, then how?

In short, I've created a basic app with a PNG Image on it that has white in it. I want all the white in the image to be transparent. Here's a screenshot of my app:

The white part around the circle is supposed to be transparent. I want to set that white color as the transparent color.

It seems like it's definitely possible in the FireMonkey (FMX) framework if you're using C++ Builder or Delphi due to this question and answer. Looks like it can also be done in design time using the Delphi or C++ Builder IDE from this answer.

If I do this during design time in a Delphi IDE, then it works fine. I can then also check the .fmx code for it and I see there's this line: MultiResBitmap.TransparentColor = 16777215. Here's the full .fmx code and IDE screenshot for that:

object MyImg: TImage
    MultiResBitmap.Height = 55
    MultiResBitmap.Width = 70
    MultiResBitmap.TransparentColor = 16777215
    MultiResBitmap = <
        item
        Width = 70
        Height = 55
        PNG = {

        end>
    Position.X = 1156.000000000000000000
    Position.Y = 1785.000000000000000000
    Size.Width = 64.000000000000000000
    Size.Height = 50.000000000000000000
    Size.PlatformDefault = False
end

But how is this done in Python via code during runtime?

Currently, I am loading the Image by going self.myImg.Bitmap.LoadFromFile(). Maybe there is a property in Bitmap or a way to set this transparency color?

Here's my full Python code:

from delphifmx import *
import os

class frmMain(Form):
    def __init__(self, owner):
        self.Caption = 'My Form with Transparent Image'
        self.Width = 800
        self.Height = 500

        self.myImg = Image(self)
        self.myImg.Parent = self
        self.myImg.Position.X = 100
        self.myImg.Position.Y = 100
        self.myImg.Width = 300
        self.myImg.Height = 300

        path = os.path.dirname(os.path.abspath(__file__))
        self.myImg.Bitmap.LoadFromFile(path + '\Win64\Debug\Assets\Dam.png')

def main():
    Application.Initialize()
    Application.Title = "My Application"
    Application.MainForm = frmMain(Application)
    Application.MainForm.Show()
    Application.Run()
    Application.MainForm.Destroy()

main()

I also tried doing it the way it seems like it is done in the .fmx code by using the MultiResBitmap Bitmap instead of normal Bitmap, but that doesn't work either:

path = os.path.dirname(os.path.abspath(__file__))
self.myImg.MultiResBitmap.TransparentColor = 16777215
self.myImg.MultiResBitmap[0].Bitmap.LoadFromFile(path + '\Win64\Debug\Assets\Dam.png')
