Tesseract.pix_read — Function

pix_read(
    filename::AbstractString;
    jpgLuminance::Bool = false,
    jpgFailOnBadData::Bool = false
)::Union{Pix, Nothing}

Load an image from from disk of an unspecified type. Returns nothing if the file could not be loaded.

Arguments:

T	Name	Default	Description
R	filename		The filename of the image to load.
O	jpgLuminance	`false`	If the image is a JPEG should we only load luminance data?
O	jpgFailOnBadData	`false`	If the image is a JPEG should we ignore bit errors?

Details:

The two optional parameters are obviously ignored if the image is not a JPEG.

pix_read(
    stream::IO
)::Union{Pix, Nothing}

Load an image from from a stream. Returns nothing if the file could not be loaded.

Arguments:

T	Name	Default	Description
R	stream		The stream to read the image from.

Details:

This implementation mirrors the API provided by Leptonica when you pass in a FILE pointer. This assumes that the remainder of the stream contains an image, so the remainder of the stream will be read and decoded as an image.

pix_read(
    data::AbstractArray{UInt8}
)::Union{Pix, Nothing}

Load an image from from a byte array. Returns nothing if the file could not be loaded.

Arguments:

T	Name	Default	Description
R	data		The byte array to read the image from.
