和“去除图片边框留白”有何不同？How is this different from Unpad Image?
本工具更接近位图边框裁切：可用左上角或指定颜色，也支持按固定像素四边裁切；“去除图片边框留白”侧重四角自动判断并可选保留边距。This tool is closer to bitmap border trim: top-left or a chosen colour, plus fixed-pixel cuts on each side. Unpad Image focuses on auto corner detection and an optional keep-margin.
固定像素留空算什么？What does a blank fixed-pixel box mean?
留空按 0 处理（这一边不裁）；只接受 0 或正整数，负数和小数会提示错误。A blank box counts as 0 (that side is not trimmed). Only 0 or whole numbers are accepted; negatives and decimals show an error.
JPG 白边裁不干净？JPG white borders not fully removed?
把容差调到 5%–15%；有损压缩的白边很少是纯白。Raise Tolerance to 5%–15%; lossy white borders are rarely pure white.
