ImageWrite
ImageWrite writes its incoming image to a file on disk. The ImageWrite node, unless defaults are overridden, converts
images from Katana's linear colorspace to the colorspace named in the filename. Katana image processing nodes
work entirely in floating point, so images are also converted from floating point to the bit depth specified in the
options for the format.
ImageWrite contains controls (channels and outputFrame) to force the output regardless of what may be coming
into the node. However, if the output format cannot support the settings (for example, .jpeg doesn't support an
alpha channel), the extra information is discarded.
The ImageWrite node supports the following file formats: .exr, .rla, .cin, .png, .tif, .tiff, .jpg, .jpeg, .dpx, and .hist.
Control (UI) Default Value Function
passName comp Sets the name used in the directories generated for
this ImageWrite node. The passName should be
unique for each ImageWrite node in the scene.
singleFrame disabled When enabled, Katana only renders a single frame
(for example, image_res.0001.exr) rather than an
image sequence (for example, image_res.#.exr). You
can specify the frame number using the frame
control below.
This also produces a render error when rendering on
any frame other than the specified frame.
