Detailed Description

Represents a single filter pass in the scaling graph.

Each filter will read from some previous pass's output, and write to a buffer associated with the pass (or into the final output image).

run

SwsPassFunc SwsPass::run

Filter main execution function.

Called from multiple threads, with the granularity dictated by slice_h. Individual slices sent to run are always equal to (or smaller than, for the last slice) slice_h.

input

SwsPass* SwsPass::input

Filter input.

This pass's output will be resolved to form this pass's. input. If NULL, the original input image is used.

output

SwsPassBuffer* SwsPass::output

Filter output buffer.

This struct is always allocated.

setup

SwsPassSetup SwsPass::setup

Called once from the main thread before running the filter.

Optional. Returns 0 or a negative error code.

free

void(* SwsPass::free) (void *priv)

Optional private state and associated free() function.
