Struct `ITXtChunk`

pub struct ITXtChunk { pub keyword: String, pub compressed: bool, pub language_tag: String, pub translated_keyword: String, /* private fields */ }

Struct encoding an iTXt chunk

Fields

keyword: String: The keyword field. This needs to be between 1-79 bytes when encoded as Latin-1.
compressed: bool: Indicates whether the text will be (or was) compressed in the PNG.
language_tag: String: A hyphen separated list of languages that the keyword is translated to. This is ASCII-7 encoded.
translated_keyword: String: Translated keyword. This is UTF-8 encoded.

Implementations

`impl ITXtChunk`

fn new(keyword: impl Into<String>, text: impl Into<String>) -> Self: Constructs a new iTXt chunk. Leaves all but keyword and text to default values.
fn decompress_text(&mut self) -> Result<(), DecodingError>: Decompresses the inner text, mutating its own state. Can only handle decompressed text up to DECOMPRESSION_LIMIT bytes.
fn decompress_text_with_limit(&mut self, limit: usize) -> Result<(), DecodingError>: Decompresses the inner text, mutating its own state. Can only handle decompressed text up to limit bytes.
fn get_text(&self) -> Result<String, DecodingError>: Decompresses the inner text, and returns it as a String. If decompression takes more than 2 MiB, try decompress_text_with_limit followed by this method.
fn compress_text(&mut self) -> Result<(), EncodingError>: Compresses the inner text, mutating its own state.
