icon in pygame does not load transparency correctly












1















I have looked over every other question related to mine and none of them worked,
here is my code so far:



icon = pygame.image.load('icon.png')

surface= pygame.Surface(icon.get_size(), depth=24)

key = (0,255,0)

surface.fill(key, surface.get_rect())

surface.set_colorkey(key)

surface.blit(icon, (0,0))

surface.set_alpha(128) 



pygame.display.set_icon(surface)


The original image is:



but when executed it still contains a black background, with a barely visable 'P'



Note: sorry for really big image not sure how to scale it down






python-3.x image pygame icons transparency

          Change your code to 



          icon = pygame.image.load('icon.png')
          
icon = pygame.transform.scale(icon, (32, 32))
          
surface= pygame.Surface(icon.get_size())
          
key = (0,255,0)
          
surface.fill(key)
          
surface.set_colorkey(key)
          
surface.blit(icon, (0,0))
          

          
pygame.display.set_icon(surface)


          Note the changes:



          I removed surface.set_alpha(128) since it will not work. Only a colorkey is supported for icons, but not per-pixel alpha.



          I changed surface.fill(key, surface.get_rect()) to surface.fill(key) because passing surface.get_rect() as argument is unnecessary.



          Also, the line icon = pygame.transform.scale(icon, (32, 32)) was added to ensure the image has the right size. Bigger sizes often do not work (depending on your OS/window manager).

          Monofisismo

          Image
          Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

          Olmecas

          Image
          Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
