WinMagnification

Python wrapper for Windows Magnification API

pip install WinMagnification

Covered functions:

• MagInitialize
• MagUninitialize
• MagGetFullscreenColorEffect
• MagSetFullscreenColorEffect
• MagSetFullscreenTransform
• MagGetFullscreenTransform
• MagSetColorEffect
• MagGetColorEffect
• MagSetWindowTransform
• MagGetWindowTransform
• MagSetWindowSource
• MagGetWindowSource
• MagSetWindowFilterList
• MagGetWindowFilterList
• MagGetInputTransform
• MagSetInputTransform
• MagShowSystemCursor

You may use old-style function names:

import win_magnification as mag
import win_magnification.old as old_mag

old_mag.MagInitialize()
old_mag.MagSetFullscreenColorEffect(mag.const.COLOR_INVERSION_EFFECT)
old_mag.MagSetFullscreenColorEffect(mag.const.DEFAULT_COLOR_EFFECT)
old_mag.MagUninitialize()

Or you may use more pythonic function names:

import win_magnification as mag

mag.initialize()
mag.set_fullscreen_color_effect(mag.const.COLOR_INVERSION_EFFECT)
mag.reset_fullscreen_color_effect()
mag.finalize()

Or... you can even use Object-Oriented wrapper:

import win_magnification as mag

api = mag.WinMagnificationAPI()
api.fullscreen.color_effect.raw = mag.const.COLOR_INVERSION_EFFECT
api.fullscreen.color_effect.reset()

Restrictions

There are 3.5 groups of functions:

• Fullscreen (nothing required, call and chill) have limited functional, but simple:
  • get/set_fullscreen_color_effect
  • get/set_fullscreen_transform
  • get_input_transform
• Window (requires window creation as shown in example), more powerful, but requires such things like custom window creation (hello from pywin32), UiAccess (Hard to obtain) if you need your magnifier above everything, but you can simulate all fullscreen functions too:
  • get/set_color_effect
  • get/set_transform
  • get/set_source
  • get/set_filters (supports exclusion only, looks like excluded windows never exist for magnifier)
• UiAccess required:
  • set_input_transform
• Other:
  • initialize
  • finalize
  • set_cursor_visibility (cursor stay hidden until active)

Known alternatives

Pymagnification

I can't actually use this lib, I don't know why, it just does nothing and imports nothing. Also, it doesn't support fullscreen* functions

Known issues

Working from different threads is pain, and I'm trying to solve/restrict this somehow

PyWin32 Integration?

This package uses ctypes only, so no pywin32 required. But, well, you can use pywin32 for creating magnifier windows and so on (see example)
