Colour/tint built-in Images

[m_doyle04]

Hi All,

I'm 99.99% sure I've read something about changing the colour/tint of Pythonista's in-built images somewhere in this forum but I've spent a long time searching and can't find it. Hopefully this post will appear more easily in searches in the future with some appropriate tags for the benefit of others.

I thought changing the colour of the in-built images would be as simple as accessing the "tint" or "tin_color" attributes of the Image object but it isn't. It's actually a real pain in the proverbial. For those interested you can do so by using the ImageContext as follows:

import ui

with ui.ImageContext(100, 100) as ctx:
	ui.set_color('red')
	img = ui.Image('iob:arrow_down_a_256').with_rendering_mode(ui.RENDERING_MODE_TEMPLATE).draw(0,0,100,100)
	img = ctx.get_image()
	img.show()

@m_doyle04, changing the tint works when the image is on a button, but not stand-alone:

from ui import *

v = Button(image=Image('iob:arrow_down_a_256'))
v.background_color = 'white'
v.tint_color = 'red'
v.present('sheet')

@enceladus thanks, I knew I'd seen that somewhere before!
