[英]Transparent Image Background Issue android
Transparent Image background converts to Black Color After placing into Android Gallery. 将透明图像背景放入Android Gallery后,将转换为黑色。 If I upload transparent image from gallery then the image background shows black color
如果我从图库上传透明图像,则图像背景显示为黑色
bitmap = eraseBG(bitmap, -1); // use for white background
bitmap = eraseBG(bitmap, -16777216); // use for black background
private static Bitmap eraseBG(Bitmap src, int color) {
int width = src.getWidth();
int height = src.getHeight();
Bitmap b = src.copy(Config.ARGB_8888, true);
b.setHasAlpha(true);
int[] pixels = new int[width * height];
src.getPixels(pixels, 0, width, 0, 0, width, height);
for (int i = 0; i < width * height; i++) {
if (pixels[i] == color) {
pixels[i] = 0;
}
}
b.setPixels(pixels, 0, width, 0, 0, width, height);
return b;
}
