我在尝试运行此程序时遇到错误。它需要一个标记为'图像并将标记的RGB值与原始图像的RGB值混合。它使用PIL和Numpy来混合两个几乎相同的图像的RGB值,使用图像' alpha通道值。我遇到的错误是:
File "wip.py", line 87, in mark
apixel[channel] = ((apixel[channel]*(apixel[3]/255))+(oapixel[channel]*(oapixel[3]/255)))/2
IndexError: index 3 is out of bounds for axis 0 with size 3
相关代码是:
img = np.array(marked)
orig_img = np.array(original_image)
for x in range(wmark_w):
for y in range(wmark_h):
if img[x][y][3] < 255:
apixel = img[x][y]
oapixel = orig_img[x+int(0.02*width)][y+int(0.02*width)]
for channel in range(4):
apixel[channel] = ((apixel[channel]*(apixel[3]/255))+(oapixel[channel]*(oapixel[3]/255)))/2
marked = PIL.Image.fromarray(img)
del img; del orig_img
&#39; oapixel&#39;因为标记位于特定的矩形
,所以是偏移的答案 0 :(得分:1)
显然原始图像不是RGBA格式。转换为:
orig_img = np.array(original_image.convert('RGBA'))
