Struct InputFileReader

pub struct InputFileReader { /* private fields */ }

InputFileReader provides a safe API over InputFile by taking ownership of the storage into which the channel data is to be read and handling all the Slice pointer offset shenanigans internally.

Implementations

impl InputFileReader

pub fn read_pixels( self, s1: i32, s2: i32, ) -> Result<(InputFile, Vec<Frame>), Error>

Read all scanlines in the range [s1, s2] and put them in the current frame buffer.

This consumes the InputFileReader and returns the original InputFile object and the Vec of the read Frames .

Errors

• Error::Base - if any error occurs

pub fn is_optimization_enabled(&self) -> bool

Check if SSE optimization is enabled. Decode times will be faster if this returns true.

Optimization depends on:

• The file type (only scanline data is supported),
• The framebuffer channels (RGB/RGBA mono or stereo)
• The framebuffer channel types (all channels half-float format only)
• The file channels (RGB/RGBA mono or stereo)
• The file channel types (all channel half-float format only)
• Whether SSE2 instruction support was detected at compile time
