libvips_ffi_api 0.1.3+8.16.0

High-level Dart API for libvips image processing library. Provides Pipeline-style chainable operations.

Changelog

0.1.3+8.16.0

✨ New Features

• Ability to Load Image from Raw Memory Data:

  • Introduced a new factory constructor VipsImg.fromRawRgba to the VipsImg class, allowing images to be created directly from raw RGBA or RGB byte arrays (Uint8List).
  • This function requires specifying the image width, height, and number of bands (channels, e.g., 3 for RGB, 4 for RGBA).
  • Note: The input buffer data is copied internally by libvips.

• Enhanced JoinPipelineSpec for Image Stitching:

  • JoinPipelineSpec now includes an addInputRawRgba method, enabling the use of raw RGBA/RGB memory data as an input source for image joining pipelines.
  • Added the corresponding JoinInputRawRgba class to encapsulate raw memory inputs.

🐛 Bug Fixes / Improvements

• Clarified the description of JoinInputBuffer (and its related methods) to explicitly indicate it is for "Input from buffer data (encoded image like PNG/JPEG)", distinguishing it from the new raw data input method.

  • Native buffer is now kept alive until dispose() is called
  • Prevents "IDAT stream error" when using images created from buffer
