wxPython中的透明图像{Mask} [英] Transparent images in wxPython {Mask}

问题描述

我已经厌倦了在网络上搜索此文件，但我无法使其正常工作.我需要将绿色像素变成透明像素，而不需要一半的透明度.想知道如何才能有效地使用遮罩，但是wx文档并没有真正的帮助...

I'm tired of searching this on the net and i cant get it to work. I need to turn green pixels into transparent ones, no half transparency needed. Wondering how can effectively use a mask, but the wx docs doesn't help much really...

希望有人可以给我小费.

Hope someone can give me a tip, regards.

png = wx.Image('sun2.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()
#print png.HasMask() fail
png.SetMaskColour((0,255,0))
#mask=wx.Mask(png,wx.Colour(0,255,0))
#png.SetMask(mask)
imge=wx.StaticBitmap(self, -1, png, (10, 5), (png.GetWidth(), png.GetHeight()))

推荐答案

您可以查看 wxpython文档和演示.
在演示蒙版中，他们展示了一种使用透明蒙版的方法:

You can check the wxpython docs and demo.
In the demo Mask they show a method to use a transparent mask:

    # Now we'll create a mask in a bit of an easier way, by picking a
    # colour in the image that is to be the transparent colour.
    self.bmp_withcolourmask  = images.TestStar2.GetBitmap()
    mask = wx.Mask(self.bmp_withcolourmask, wx.WHITE)
    self.bmp_withcolourmask.SetMask(mask)
