kapy

Kapy is a simple utility designed to copy digital camera photos from an SD card to a disk with transformations. This tool streamlines the process of transferring photos from your camera to your computer, while also providing the ability to make any necessary image transformations during the copying process.

• Convert from JPEG to HEIC
• Merge GPS information into EXIF from .gpx files on Google Drive
• Adjust image size and compression ratio based on EXIF rate information

Disclaimer

To access Google Drive API using your own Google OAuth 2.0 clientid and clientsecret, you will need to set up a project on the Google Developers Console and create OAuth 2.0 credentials. Once you have obtained your credentials, you can set the CLIENTID and CLIENTSECRET as environment variables or include them directly in your code.

shell $ CLIENT_ID={YOUR_CLIENT_ID} CLIENT_SECRET={YOUR_SECRET} kapy login $ kapy clone

If you encounter login issues, you can log in again as follows.

shell $ kapy clean $ CLIENT_ID={YOUR_CLIENT_ID} CLIENT_SECRET={YOUR_SECRET} kapy login

Or, you can assign CLIENTID and CLIENTSECRET values at compile time.

```shell $ CLIENTID={YOURCLIENTID} CLIENTSECRET={YOUR_SECRET} cargo install kapy

OR

$ CLIENTID={YOURCLIENTID} CLIENTSECRET={YOUR_SECRET} cargo build ```

The Google Drive API has a strict application approval process since it can access users' sensitive information. This application was originally created for my personal use, and it is difficult to comply with Google's strict approval process. You should refer to the following document to generate your own Google OAuth 2.0 credentials:

https://developers.google.com/identity/protocols/oauth2/native-app

The following API scopes must be specified:

• https://www.googleapis.com/auth/drive.metadata.readonly: See information about your Google Drive files.
• https://www.googleapis.com/auth/drive.readonly: See and download all your Google Drive files.

Configurations

• An example ```yaml default_path: from: /Volumes/Untitled/DCIM/108HASBL to: ~/images polices:
• rate: [5] commands: resize: 100% # default value; ignore it format: preserve # default value
• rate: [4] commands: quality: 95% format: heic
• rate: [1,2,3] commands: resize: 50% # resize image to 50% quality: 95% format: heic
• rate: [0] commands: resize: 36m # resize image to 36m pixels quality: 92% format: heic ```
