Read an OpenEXR image
Description
Load an RGBA OpenEXR image into R numeric matrices.
Usage
read_exr(path, array = FALSE)
Arguments
path |
Character scalar. Path to an '.exr' file. |
array |
Default 'FALSE'. Return a 4-layer RGBA array instead of a list. |
Value
A list with elements 'r', 'g', 'b', 'a' (numeric matrices), and the integer dimensions 'width', 'height'.
Examples
#Write the included data to an EXR file
tmpfile = tempfile(fileext = ".exr")
write_exr(tmpfile,
widecolorgamut[,,1],
widecolorgamut[,,2],
widecolorgamut[,,3],
widecolorgamut[,,4])
exr_file = read_exr(tmpfile)
str(exr_file)
Wide Color Gamut EXR Data
Description
Wide Color Gamut numeric data in RGBA list format from the OpenEXR project.
Usage
widecolorgamut
Format
An array of four channels (RBGA) and a width/height

Write an OpenEXR image
Description
Save RGBA numeric matrices to an OpenEXR file (32‑bit float, ZIP compression).
Usage

Arguments
path |
Character scalar output file. |
r |
Numeric matrix, red channel. |
g |
Numeric matrix, green channel. |
b |
Numeric matrix, blue channel. |
a |
Numeric matrix, alpha channel. |
Value
None.
Examples
#Write the included data to an EXR file
tmpfile = tempfile(fileext = ".exr")
write_exr(tmpfile,
widecolorgamut[,,1],
widecolorgamut[,,2],
widecolorgamut[,,3],
widecolorgamut[,,4])
