Struct gifski::Collector

pub struct Collector { /* private fields */ }

Collect frames that will be encoded

Note that writing will finish only when the collector is dropped. Collect frames on another thread, or call drop(collector) before calling writer.write()!

Implementations

impl Collector

pub fn add_frame_rgba( &self, frame_index: usize, frame: ImgVec<RGBA8>, presentation_timestamp: f64 ) -> GifResult<()>

Frame index starts at 0.

Set each frame (index) only once, but you can set them in any order. However, out-of-order frames will be buffered in RAM, and big gaps in frame indices will cause high memory usage.

Presentation timestamp is time in seconds (since file start at 0) when this frame is to be displayed.

If the first frame doesn’t start at pts=0, the delay will be used for the last frame.

If this function appears to be stuck after a few frames, it’s because crate::Writer::write() is not running.

pub fn add_frame_png_data( &self, frame_index: usize, png_data: Vec<u8>, presentation_timestamp: f64 ) -> GifResult<()>

Decode a frame from in-memory PNG-compressed data.

Frame index starts at 0. Set each frame (index) only once, but you can set them in any order. However, out-of-order frames will be buffered in RAM, and big gaps in frame indices will cause high memory usage.

Presentation timestamp is time in seconds (since file start at 0) when this frame is to be displayed.

If the first frame doesn’t start at pts=0, the delay will be used for the last frame.

If this function appears to be stuck after a few frames, it’s because crate::Writer::write() is not running.

pub fn add_frame_png_file( &self, frame_index: usize, path: PathBuf, presentation_timestamp: f64 ) -> GifResult<()>

Read and decode a PNG file from disk.

Frame index starts at 0. Set each frame (index) only once, but you can set them in any order.

Presentation timestamp is time in seconds (since file start at 0) when this frame is to be displayed.

If the first frame doesn’t start at pts=0, the delay will be used for the last frame.
