Java version (just translated from Kotlin) int width = image. Val alpha = ((maskAlpha * imageAlpha) * 255).toInt() shl 24 Val imageAlpha = ((imgData shr 24) and 0x000000FF) / 255f Val maskAlpha = (maskData and 0x000000FF)/ 255f Mask.getRGB(0, y, width, 1, maskData, 0, 1) This.getRGB(0, y, width, 1, imgData, 0, 1) I wrote this code in Koltin, the key point here is that if you have the alpha on your original image you need to multiply these channels. It uses a slightly more Java-ish method, using standard classes to process/filter images.Īctually, my method uses a bit more memory (making an additional image) and I am not sure it is faster (measuring respective performances could be interesting), but it is slightly more abstract.įor those who are using alpha in the original image. Note that the mask image is gray levels, black becoming full transparency, white becoming full opaque.Īlthough you have resolved your problem, I though I could share my take on it. The remainder just display the images in a little Swing panel. Private BufferedImage ApplyTransparency(BufferedImage image, Image mask)ĪlphaComposite ac = AlphaComposite.getInstance(AlphaComposite.DST_IN, 1.0F) It uses a slightly more Java-ish method, using standard classes to process/filter images. Although you have resolved your problem, I though I could share my take on it. Return Toolkit.getDefaultToolkit().createImage(ip) Note that the mask image is gray levels, black becoming full transparency, white becoming full opaque.

Tiempo despus vine a descubrir que el hombre detrs de la mscara era Ral Carbonell Hijo. La jodia mscara aquella era la cosa ms fea que haba visto en mi vida. Papos hand painted figures take imagination to the next level. Cuando era nio, el personaje de Papo Swing me daba miedo. This is the Papo Knight With Iron Mask Animal Figure 36031 produced by Papo.

M_images = ImageIO.read(new File("E:/Documents/images/mapMask3.png")) M_images = ImageIO.read(new File("E:/Documents/images/map.png")) Located on a busy street that leads to the Tourism Village. Many artists choose the Image Factory to launch their new works, be it a new painting, exhibition, book, music album or poetry. Here are the relevant bits: TestMask() throws IOException This riverside gallery is the leading art gallery and center for up and coming artists in Belize. I took my little test program and tweaked it a bit to get the wanted result. I played recently a bit with this stuff, to display an image over another one, and to fade an image to gray.Īlso masking an image with a mask with transparency (my previous version of this message!).
