Converts an image of one type to another type. The type is determined by the extension on the file.

The -d option is used to specify the bit-depth of the output file.

• -d byte,char,8 = 8 bit unsigned int

• -d short,16 = 16 bit unsigned int

• -d half = 16 bit floating point

• -d float = 32 bit floating point

When the input format is ambiguous (i.e. reading from stdin), you can forcibly specify the input format using the -n option. The -t option can be used to forcibly specify the output format (regardless of file extension).

The -g option controls whether gamma conversion is done when converting formats. For example, .exr files are typically in linear format while .jpg files have a gamma applied. The default value for this option is determined by the environment variable HOUDINI_AUTOCONVERT_IMAGE_FILES and the expected options are

• auto : perform gamma conversion if required

• off : do not perform gamma correction

The -L option specifies the input cineon LUT, while the -O specifies the output cineon LUT.

iconvert will now apply a gamma correction to color planes when converting between formats of different types, if those formats have different colorspaces. This can be disabled with the -g off parameter.

By default tags are passed to the output image. Tags may optionally be prefixed with "in:" or "out:" to specify that the tag should be associated with either the input or output image.
