Choose format or quality for "Save Canvas"?
-
Would it be possible in the future to allow us to choose a format (JPEG or PNG) or at least to specify the quality of the saved image? I'm seeing JPEG compression artifacts in some of the artwork I'm generating from Pythonista.
-
See Brumm's PhotoText.py... He does:
clipboard.set_image(background, format='jpeg', jpeg_quality=0.98) photos.save_image(clipboard.get_image())
-
Sorry, I should have specified that I'm working with the canvas library, which doesn't seem to have any affordances for getting the current canvas as an image to work with.

There is an undocumented console.save_raw_image_data() function that takes 5 arguments:
>>> import console >>> dir(console) """['__doc__', '__name__', '__package__', 'alert', 'clear', 'hide_activity', 'hide_output', 'hud_alert', 'input_alert', 'login_alert', 'password_alert', 'quicklook', 'save_raw_image_data', 'secure_input', 'set_color', 'set_font', 'show_activity', 'show_image', 'write_link']""" >>> console.save_raw_image_data() """Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: function takes exactly 5 arguments (0 given)"""
-
From Image.Py
console.save_raw_image_data(image_data, 'RGBA', image_to_save.size[0], image_to_save.size[1], filename)
-
Hmm, wondering if we can get the raw image data from canvas in the future.
