beforeWrite is called before [WriteHeader] and [Write]

callFinishFn calls the finish functions registered with the AsyncBuffer.

closeGroup closes the most recently opened group in the buffer.

closeGroup closes the most recently opened group of attributes.

countNewLines counts the number of new lines in the given byte slice and increments the decoder's line counter accordingly.

fetch ensures the buffer contains at least 'need' bytes

flushNextChunk unlocks the reader, allowing it to return the next chunk of data

format formats a log record and writes it to the buffer.

getFreePort finds an available TCP port

getImageSize returns the width and height of the image, taking into account orientation and animation.

grow ensures that the buffer has at least n free bytes of capacity. It grows the buffer to the next power of two if necessary.

isSpace checks if a byte is a whitespace character.

mainPipeline constructs the main image processing pipeline. This pipeline is applied to each image frame.

helper creates a minimal request object with given config and optional headers

makeTargetPath creates the target directory and returns file path for saving the image or hash.

mustPeekBuffered peeks at all currently buffered bytes without advancing the reader. If no bytes are buffered, it peeks at least 1 byte. If an error o

mustReadWhileFn reads bytes to the buffer while the provided function returns true. The byte that causes the function to return false is not included

newFormatterJSON creates a new formatterJSON instance.

newRegistry creates a new image type registry.

newVipsSource creates a new VipsAsyncSource from an io.ReadSeeker.

offsetAvailable checks if the data at the given offset is available for reading. It may return io.EOF if the reader is finished reading and the offset

openGroup opens a new group in the buffer.

openGroup opens a new group of attributes.

openGroup opens a new group of attributes.

parseHexRGBColor parses a hex-encoded RGB color option value

parseQualityInt parses a quality integer option value (minQ-100)

parseResolution parses a resolution option value in megapixels and stores it as pixels

peek peeks at the next n bytes without advancing the reader. If an error occurs, it sets d.err and returns false.

readChunkAt copies data from the chunk at the given absolute offset to the provided slice. Chunk must be available when this method is called. Returns

readChunks reads data from the upstream reader in background and stores them in the pool

readName reads a name (tag or attribute) to the buffer until a non-name byte is encountered.

readUntil reads bytes to the buffer until the specified delimiter byte is encountered. The delimiter byte is included in the buffer. If an error occur

sendRequest is a common logic between sync and async download.

setMetadata sets metadata on the given New Relic attributable entity

setMetadata sets metadata on the given DataDog span

setMetadata sets metadata on the given OpenTelemetry span

setReader sets a new reader for the decoder, wrapping it in a bufio.Reader from the pool.

startDuration starts a timer and returns a cancel function to record the duration

vipsErrorMessage reads VIPS error message

withGroup returns a new handler with the given attribute group added.

writeChildrenTo writes all child tokens of the node to the provided writer.

AddCancel attaches a cancel function to the image data

AddHook adds a new hook to the handler.
