Tesseract.pix_write_png — Function
pix_write_png(
    filename::AbstractString,
    pix::Pix
    gamma::AbstractFloat = Float32(0.0)
)::Bool

Write an image to a file in the PNG image format. If there is an error false is returned.

Arguments:

TNameDefaultDescription
RfilenameThe name of the file to write to.
RpixThe image to write to the file.
OgammaFloat32(0.0)The gamma value to write to the header.

Restrictions:

  • gamma - Must be in the range 0.0 to 1.0 inclusively.

Details:

If the file exists it will be overwritten. If gamma is set to 0.0 then no gamma value will be written to the file.
