NAME
layerutil create compiled layered image stack
SYNOPSIS
layerutil [-Vlhogspf] inputfile
DESCRIPTION
Creates a compiled layered image stack (lcr) file from a layered input
file source, such as an lsr or suitably structured Photoshop (psd) file.
If the psd file's basename ends with @Yx Y will be treated as the scale
factor of the psd file. If gpu compression is not specified then lossy
compression is used.
OPTIONS
The following options are available:
-c Convert to lcr format.
-f s, --flattened-image
Saves the flattened image as a jpeg to the output path
given by the -o flag. if the output filename doesn't
end with .jpeg or .jpg then the file extension that was
given will be removed and jpeg will get added. If the
file that gets written out is a JPEG image, the result-
ing image will be compressed with the default compres-
sion options.
-g s, --gpu-compression=s
Sets program to use gpu optimized compression. You can
choose either best or smallest. GPU Compression is only
supported on iOS 10.0/AppleTV 10.0 or greater.
-l n, --lossy-compression=n
Set the lossy compression factor used for image content
to a value between 0 and 1.0, default is 0.75. The
smaller the value, the smaller the compressed file
size. A value of 1.0 creates a lossless image.
-s n, --scale=v Used to specify the scale factor used in the generated
lcr file. When used with a PSD file it indicates the
scale factor of the PSD file. When used with an LSR
file indicates which scale factor of images should be
kept. If scale is not specified 1 is assumed.
-p n, --display-gamut=v
v can be one of srgb/p3. Selecting p3 processes the
image and if it contains wide gamut data will be
treated as such.
-o, --output Output file name. If you are converting an input
lsr/psd file then if no output file is given, the base-
name of the input file is used as the output file name
with an appended .lcr extension. unless you are
-h, --help Prints out usage information.
-V, --version Prints out version information.
