[Python] Python PIL image text overlay not displayed with expected color on white background...

Python PIL Image not working properly with overlay text image. I am trying to use FPDF image to convert an overlayed text png image to pdf file. However, the overlay text is not in expected colour (looks transparent) on a white background image. However, the same logic works in a zebra pattern background image.

Source background image:



Text overlayed image:



Code used for overlayed text: Python Image AttributeError: 'ImageDraw' object has no attribute '__array_interface__'

code:

fontuse = "D:/Ubuntusharefolder/CustomFonts/EnglishFonts/NotoSans-Medium.ttf"
font_color_bgra = (0,0,0,0)#black #(0,255,0,0)#green
font = ImageFont.truetype(fontuse, 32 * int(2), layout_engine=ImageFont.LAYOUT_RAQM)

src_img_use = np.array(Image.open(os.path.join(input_subfolder_path, filename) ) ) #(511, 898, 4)
print('src_img_use gen size: ',os.path.join(input_subfolder_path, filename), src_img_use.shape)
src_img_pil = Image.fromarray(src_img_use)
print('src_img_pil gen size: ', src_img_use.size)

img_pil_4dtxt = ImageDraw.Draw(src_img_pil)
img_pil_4dtxt.text(textpos, subjectuse, font = font, fill = font_color_bgra) #fill = "black" )

src_img_pil.save(output_folder_final_path + '/updtxtimg/' + str(imgidx) + '_' + filename)
print('label_img_withtxt drawtext saved subjectuse idx', imgidx, subjectuse)


Note sure whether there is a problem with input image or overlay code logic. The same image has to be used in FPDF.image but same behavior noticed.
