bufferedImage.getRGB(x, y) does not yield alpha
bufferedimage, colors, java, rgb
Solution
The single-parameter `Color` constructor you're using discards alpha information. Use the two-parameter version instead and pass in `true` for `hasalpha`:
Color c = new Color(i.getRGB(x, y), true);
The relevant Javadoc:
`Color(int rgb)`
Creates an opaque sRGB color with the specified combined RGB value consisting of the red component in bits 16-23, the green component in bits 8-15, and the blue component in bits 0-7.
`Color(int rgba, boolean hasalpha)`
Creates an sRGB color with the specified combined RGBA value consisting of the alpha component in bits 24-31, the red component in bits 16-23, the green component in bits 8-15, and the blue component in bits 0-7.
Problem
I've got a BufferedImage `i` and I'd like to get the Color from a certain pixel of that `image` including the alpha value. The pixel is identified using `x` and `y` coordinates. Here's what I tried: ``` Color c = new Color(i.getRGB(x, y)); ``` For some reason, the new color object contains the correct RGB but the alpha gets lost. What am I doing wrong? Thanks in advance
