Digitrail 数痕
Scattered screenshots and screen recordings become one complete, page-numbered document you can actually print and hand over.
把零散的截图与录屏，拼成一份完整、带页码、可以直接打印提交的材料。
What it does
它能做什么
Capabilities-
Stitch screenshots into one image把多张截图拼成一张长图
Overlapping and out-of-order shots are aligned and joined into one continuous image, with the seams cleaned up rather than left visible.重叠、乱序的截图会被对齐并接成一整张，接缝做清理，而不是留着一条条断口。
-
Turn screen recordings into a still image把录屏转成静态长图
For content that only exists as video. Frames are sampled while you record, blurry ones are dropped, and the rest are stitched into one image.针对只以视频形式存在的内容：录制时抽帧，模糊帧丢弃，其余按序拼接成一张图。
-
Export as a paginated PDF按纸张规格分页导出 PDF
The long image is laid out onto A4 pages with page N of M printed on every page, so a printout keeps its order once it leaves your hands.长图按 A4 排成多页，每页印上「第 N 页 / 共 M 页」—— 打印出来交出去，顺序不会乱。
-
Combine separate images把多张图片合成一页
Several images onto one sheet in the layout you pick: stacked, side by side, 2×2 or 3×3, scaled by the smallest one, never stretched.多张图片按你选的排版合成一页：上下、左右、2×2、3×3；以最小尺寸为准缩放，不做拉伸。
-
Mark it as yours加上可核验的标注
Timestamp, free-text annotations and blur blocks are burned into the output, added by you on purpose and visible on the printout.时间戳、文字标注与模糊遮盖会烧进成品 —— 由你主动添加，且在打印件上看得见。
-
Long-image text recognition长图文字识别
Segments a long image and reads the text on it, so long captures stay searchable. Runs on the bundled model, offline.对长图做分段与文字识别，让长截图里的内容仍可被检索。使用随包模型离线运行。
