Drawing a image with a "tint_color" in an ImageContext
Like every thing else, this is not my strong suit. I would just like to render/draw the built in images as @omz does with a tint_color
In the code Snippet below, you can see I have been trying some things. I am sure it's so easy if you know how. I really do try before asking here. Then the brain just gets full.
if self.image_name: with ui.GState(): ui.set_color('blue') #ui.set_shadow() #ui.set_blend_mode(30) #print(ui.BLEND_DESTINATION_IN) img = ui.Image.named(self.image_name) img_rect = ui.Rect(*bounds).inset(*self.image_margin) if img: img.draw(*img_rect)
Edit. Black and white pictures from Pythonista selection render fine, but only in black or white
have you tried the ui.Image method
with_rendering_mode(ui.RENDERING_MODE_TEMPLATE)? I believe this is what ui.Button's use to do the tinting (the image must have an alpha channel)
img=ui.Image.named('iow:alert_32') with ui.ImageContext(100,100) as ctx: ui.set_color((1,0,0)) img.with_rendering_mode(ui.RENDERING_MODE_TEMPLATE).draw() out=ctx.get_image() out.show()
@JonB , thanks.
Works perfectly. In this case drawing to the screen from the draw method
Ok, to be more correct if someone following this thread.
I am sort of using like this. not saying it's good. Just wanted to show for completeness.
import ui class MyClass(ui.View): def __init__(self, image_name, tint_color = 'black', shape_bg_color = 'orange', *args, **kwargs): super().__init__(*args, **kwargs) self.image_name = image_name self.image_margin = (20, 20) self.tint_color = tint_color self.shape_bg_color = shape_bg_color def draw(self): with ui.GState(): ui.set_color(self.shape_bg_color) shape = ui.Path.oval(*self.bounds) shape.fill() ui.set_color(self.tint_color) img = ui.Image.named(self.image_name) img_rect = ui.Rect(*self.bounds).inset(*self.image_margin) if img: img.with_rendering_mode(ui.RENDERING_MODE_TEMPLATE).draw(*img_rect) if __name__ == '__main__': wh = 300 mc = MyClass('iow:ios7_stopwatch_256', frame = (0, 0, wh, wh), bg_color = 'purple', shape_bg_color = 'white', tint_color = 'black') mc.present('sheet')
