About Image Rotation
Photos taken with a smartphone or scanned images may appear sideways or upside down. The image rotation feature lets you correct image orientation directly in your reading logs. Rotated images are automatically saved to Google Drive, so they display correctly from then on.
Rotation Types
Three types of rotation are available:
Rotate 90° Right
Rotates the image 90° clockwise
Rotate 90° Left
Rotates the image 90° counterclockwise
Rotate 180°
Flips the image upside down (180° rotation)
How to Rotate an Image
-
Click an Image in Your Notes
Click on an image displayed in the notes area to open a context menu -
Choose a Rotation Direction
Select [Rotate 90° right], [Rotate 90° left], or [Rotate 180°] from the menu -
Wait for Auto-save
A loading indicator appears during rotation. The rotated image is automatically uploaded to Google Drive
Image rotation is only available for Google Drive images. Images pasted in
<img href="drive.google.com/..."> format can also be rotated. For non-Drive images, selecting rotation will display "Only Google Drive images can be rotated".
How Rotation Works
When you rotate an image, the following steps are performed automatically:
- The image is rotated by the specified angle
- The rotated image is uploaded to Google Drive as a new file
- The old image is moved to the Google Drive trash
- The image reference in your notes is updated to the new file name
Image rotation supports undo/redo. Use [Undo] (Ctrl+Z) to revert to the pre-rotation state. You can also rotate in the opposite direction or recover the original image from Google Drive's trash.
Use Cases
Correcting Smartphone Photos
When photos of book pages taken with a smartphone appear sideways, use rotation to quickly fix the orientation.
Pre-Recognition Image Correction
Text recognition accuracy is affected by image orientation. Rotating a sideways image before running text recognition can improve results.
Fixing Scanned Image Orientation
If a scanned image appears upside down, use the 180° rotation to quickly correct it.
FAQ
Q: Can I rotate images without connecting to Google Drive?
Rotation is only available for Google Drive images. For non-Drive images (embedded or external URL images), selecting rotation will display "Only Google Drive images can be rotated".
Q: Does rotation degrade image quality?
Images are saved in JPEG format at 92% quality, so there may be slight quality loss, but it is generally imperceptible in normal use.
Q: Can I undo a rotation?
Yes, use [Undo] (Ctrl+Z) to revert to the pre-rotation state. You can also rotate in the opposite direction or recover the original image from Google Drive's trash.
