如何使用「截图拼长图（自动去重叠）」？How do I use the Long Screenshot Stitcher?
按顺序选择多张截图（滚动截图时每张之间最好有一些重叠），工具会自动对齐并去掉重复内容。勾选“去掉重复的顶部栏 / 底部栏”可以只保留第一张的标题栏。如果某处没对齐，可以在表格里修改该截图要裁掉的像素，然后下载长图。Select the screenshots in order (some overlap between them helps). They are aligned and duplicate content is removed automatically. Tick “Remove repeated top/bottom bars” to keep only the first header. If a seam is off, edit that screenshot’s crop in the table, then download.
为什么自动去重叠没有对齐？Why didn’t the overlap detection line up?
自动识别需要相邻两张截图有一段相同的内容。如果截图之间没有重叠、或者重叠区域是纯色背景，可能识别不准，可以关闭“自动去除重叠”后在表格里手动填写裁掉的像素。Detection needs a stretch of identical content between neighbours. With no overlap or a plain background it may fail — turn off auto-removal and enter the crop for each shot manually.
拼好的长图太长发不出去怎么办？The long image is too long to send — what now?
设置“超长时分段导出”的最大高度（例如 10000 像素），会自动拆成几张导出并打包。也可以用“长图切割”工具按比例切成多张。Set a maximum segment height (e.g. 10,000 px) and the result is split into several images in a ZIP, or use the Long Image Splitter.
支持手机截图吗？Does it work with phone screenshots?
支持。手机和电脑截图都可以，宽度不同的截图会自动缩放到第一张的宽度。在手机浏览器里直接从相册选择多张截图即可。Yes — phone and desktop screenshots both work, and different widths are scaled to the first one. On a phone just pick the screenshots from your gallery.
