Pet Image Resource Import

Pet Image Quality Detection

Feature Introduction

The initialization and import of pet image resources rely on the following two key capabilities:

  1. Image Selection

    • chooseImage: Supports end-users in selecting images from the local gallery or using the camera to take photos.

  2. Image Compression

    • resizeImage: Compresses images by first cropping them to the target dimensions while maintaining the original aspect ratio, then performing quality compression based on file size limits.

Notes

    1. When using the resizeImage API, the parameter maxFileSize is in bytes. Please pay attention to unit conversion when limiting the maximum image size.
