2. The Problem
4. . .
5. . .
6. Solution Part 1
9. . . 5 shapes
10. . . 5 shapes top top w/red bottom middle “standalone”
11. . . 3 states
12. . . 3 states regular pressed focused
13. . . 4 resolutions
14. . . 4 resolutions mdpi hdpi xhdpi xxhdpi
16. oh no!
17. Solution Part 2
20. sizes = { mdpi: 1.0, hdpi: 1.5, xhdpi: 2.0, xxhdpi: 3.0 }
21. shapes = { standalone: [ true, true ], top: [ true, false ], top_dark: [ true, false ], bottom: [ false, true ], middle: [ false, false ] } modes = { resting: WHITE, pressed: pressed(WHITE), focused: ChunkyPNG::Color.rgb(193, 232, 247) }
22. sizes.each do |dpi, factor| shapes.each do |shape, args| # compute bounds modes.each do |maincolor| png = ChunkyPNG::Image.new(width, height, TRANSPARENT) # draw shape and 9-patch bounds! fn = File.join(File.dirname(__FILE__), "..", "res" , "drawable -#{dpi}", "venuepicker_#{shape}_#{ mode}.9.png") png.save(fn) end end end
