Tesseract.pix_write_ps — Function

pix_write_ps(
    filename::AbstractString,
    pix::Pix;
    box::Union{PixBox, Nothing} = nothing,
    ppi::Integer = Int32(300),
    scale::AbstractFloat = Float32(1.0)
)::Bool

Write an image to a PostScript file. If there is an error false is returned.

Arguments:

T	Name	Default	Description
R	filename		The name of the file to write to.
R	pix		The image to write to the file.
O	box	`nothing`	Location to have the image appear on the page.
O	ppi	`Int32(300)`	The resolution to use for the image.
O	scale	`Float32(1.0)`	Scale the image on the page.

Restrictions:

ppi - Must be greater than 0.
scale - Must be greater than or equal to 0.0.

Details:

If the file exists it will be overwritten.

If you don't want the image scaled set the scale to 1.0. If you want to position the image on the page you can use a box however set w and h to 0, then the image will be positioned where you want it and not scaled.

If you want the image to be a specific size set the scale to 0.0 and use a box setting w and h to the width and height you want in thousandth of an inch. So a width of 5000 and a height of 2000 will give you an image that is 5 inches across and 2 inches high.

If you want the image scaled set the scale to the factor you desire. Value of 0.5 will cause the image to be halfed, while a value of 2.0 will double the size of the image. If you want to also position the image on the page use a box but set the w and h values to 0.
