MSI UI Icon

[tmontes]

Follow-up from #90.

• The minimal MSI installation progress UI displays a generic icon.
• It would be nice for it to include the given application's icon, if any.

(maybe addressing #91, requiring changes to the install progress UI, helps us understand how to attain this) :)

NOTE:

• While addressing Optional license agreement #91 under Optional license agreement requirement #105, learned that we will need two bitmaps for the MSI UI.
• Per the WiX docs at https://wixtoolset.org/documentation/manual/v3/wixui/wixui_customizations.html:
  • WixUIDialogBmp is a 493×312 pixel bitmap.
  • WixUIBannerBmp is a 493×58 pixel bitmap.

IDEA:

• Maybe we could use pillow to auto-generate such bitmaps if/when an icon is given.
• How hard can that be? :-)

PROGRESS:

• Played around a bit with pillow.
• This mini program produces a simple banner given an ICO file.
• Pimping things up a bit could be nice... (how?)

#!/usr/bin/env python3.7

from PIL import Image


BANNER_WIDTH = 493
BANNER_HEIGHT = 312
BANNER_LEFT = 164

BANNER_BACK = 'white'

ICON_WIDTH = 64
ICON_HEIGHT = 64

ICON_X = (BANNER_LEFT - ICON_WIDTH) // 2
ICON_Y = 24


if __name__ == '__main__':

    ico = Image.open('mu.ico')
    ico64 = ico.resize((ICON_WIDTH, ICON_HEIGHT))

    banner = Image.new('RGBA', (BANNER_WIDTH, BANNER_HEIGHT), BANNER_BACK)
    banner.alpha_composite(ico64, (ICON_X, ICON_Y))

    banner.save('banner.png')

NEXT:

• Let's try and integrate such a banner into the MSI files, shall we?

CLOSING:

• Just merged PR Generate bitmaps with the given logo for Win MSI UI. #172.
• One less thing todo under Better MSI Packaging #85.
