怎么判断边框？How is the border detected?
先在四个角的颜色中选出沿图片边缘出现次数最多的那个作为边框色，再从四边向内裁掉所有像素都与边框色一致（每个通道相差 ≤ 容差）的整行和整列。颜色不同的单色行列（例如色带）不会被裁掉。完全透明的像素算作单独的边框色（显示为“透明”），不会被当成黑色。容差 0 只裁完全相同的颜色；整张图都是边框色时不裁剪。Of the four corner colours, the one that appears most often along the image edges is taken as the border colour. Rows and columns are then trimmed inward from each side while every pixel matches that colour (each channel within the tolerance). Single-colour rows or columns of a different colour, such as colour bands, are kept. Fully transparent pixels count as their own border colour (shown as 'transparent') and are never mixed up with black. Tolerance 0 trims only the exact colour; if the whole image is the border colour, nothing is trimmed.
