图片 - 按以下方式旋转 EXIF 数据 - 自动方向 Make

旋转 EXIF 数据 是一个 Make 模块 PDF4me 读起来像是 EXIF 方向标签 JPG 或者 PNG 它可以自动将图像旋转到正确的竖直位置。在将智能手机拍摄的照片上传到图库、打印或进行其他操作之前，可以使用此功能来校正照片的横屏方向。 PDF无需手动旋转角度。

本模块的功能

PDF4me 旋转 EXIF 数据 提供基于以下内容的自动图像旋转 EXIF 方向元数据 Make 场景。它读取 EXIF 从图像中提取方向标签（智能手机和相机照片中常见），并应用正确的旋转，从而实现正确的照片显示、打印准备、网络发布和自动方向校正工作流程。

您不容错过的重要事实

无需旋转角度

该模块读取 EXIF 方向标签直接旋转，因此可以根据每张图片进行调整，而无需像手动旋转模块那样设置固定的角度值。

图像类型必须与实际格式匹配

将图像类型设置为 JPG 或者 PNG 为了与实际文件匹配。声明的类型与实际格式不匹配会导致无法正确处理。

不包含 EXIF 数据的图像将保持不变。

屏幕截图、扫描文档或已去除元数据的图像没有 Orientation 标签可供读取，因此该模块会保留其原有方向。

PDF4me 的“根据 EXIF 数据旋转”模块已配置，文件映射自之前的模块，图像文件名和图像类型均设置为 JPG，以实现自动方向校正。 — 映射源图像，设置图像文件名和图像类型。该模块读取 EXIF 方向标签，自动旋转图像。

旋转的参数有哪些 EXIF 数据需求？

必需的： 必须提供连接信息、文件、图像文件名和图像类型。

实用技巧

Image Type must match the real file format

Setting Image Type to PNG for a file that is actually a JPG (or vice versa) can prevent correct processing. Confirm the format before mapping it in.

Run this before resizing or compressing

Apply EXIF rotation first in your scenario, then resize or compress. Correcting orientation after a resize can compound cropping issues on non-square images.

Re-saved images may have lost EXIF data

If a photo has already passed through another editor or platform that strips metadata, there may be no Orientation tag left to read, and the image will pass through unrotated.

Different phone models write different orientation values

The EXIF Orientation tag can be any value from 1 to 8, not just "rotated 90 degrees." The module handles all standard EXIF orientation values, including mirrored orientations.

This does not read GPS or camera-model EXIF fields

Rotate by EXIF Data uses only the Orientation tag. Use Image - Extract Metadata if your workflow also needs GPS coordinates, camera model, or capture timestamp.

Screenshots typically have no orientation tag

Screenshots and many desktop-generated images never carry an EXIF Orientation tag, so this module has nothing to correct on them and will pass them through unchanged.

常见问题解答

What is EXIF orientation and why do photos appear sideways?+

Many smartphone and camera sensors always capture image data in the same physical orientation and record which way the device was actually held in the EXIF Orientation tag (a value from 1 to 8) instead of rotating the pixel data itself. Viewers that ignore this tag display the photo sideways or upside down even though the file itself is fine. Rotate by EXIF Data reads that tag and physically rotates the pixels to match, so the image displays correctly everywhere, including viewers that do not read EXIF metadata. See this <a href="https://superuser.com/questions/36645/how-to-rotate-images-automatically-based-on-exif-data" target="_blank" rel="noopener noreferrer">community explanation of EXIF-based auto-rotation</a> for more background.

Do I need to specify a rotation angle manually?+

No. The module reads the EXIF Orientation tag automatically and applies the correct rotation without you specifying degrees. This is different from a manual Rotate module where you set a fixed angle; EXIF-based rotation adapts per image based on how each photo was actually captured.

What happens if an image has no EXIF orientation data?+

If the source image has no EXIF Orientation tag (common with screenshots, scanned documents, or images already re-saved without metadata), the module leaves the image orientation unchanged since there is no tag to read. Verify Image Type matches the actual file format before running the module, since a mismatched type can prevent correct processing.

How is this different from the general Rotate an Image module?+

The general Rotate an Image module applies a fixed angle you specify (e.g. 90 or 180 degrees) to every image. Rotate by EXIF Data instead reads each image's own Orientation tag and applies whatever correction that specific photo needs, which is why it works well on batches of photos with mixed orientations from different phones or cameras.
