我正在使用影像在 Rust 中打開和讀取影像。我使用 Windows Snipping 工具將螢屏截圖另存為影像，并嘗試打開它
let image_path = "C:/Users/mason/rust-projects/image-test/image.png";
let image = image::open(image_path).unwrap();
let _ = image;
但我得到了錯誤：
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Decoding(DecodingError { format: Exact(Png), underlying: Some(Format(FormatError { inner: DuplicateChunk { kind: ChunkType { type: gAMA, critical: false, private: false, reserved: false, safecopy: false } } })) })', src\main.rs:82:12

如果我嘗試打開用手機拍攝的照片，效果很好。如何在 rust 中打開螢屏截圖？
uj5u.com熱心網友回復：
我能夠重現。這似乎是由于crate 版本中引入的錯誤。您不必手動操作影像，而應該簡單地使用以前的版本：png0.17.4
[dependencies]
image = "0.24.0"
png = "=0.17.3"
