This display driver lets you write the rendered image into a TIFF file. Compressed TIFFs and cropping are supported. Only RI_RGB, RI_RGBA, RI_A are supported for now. This display driver understands the following parameters.
"string fullimage" ["on"]
CropWindow
, this parameter enables you to create an image of the original size, with the cropped region placed inside. Areas that are outside the crop window will be set to black (and alpha will be 0). This option is useful when compositing a cropped image with a matching complete image. The default value is `off'.
"string compression" ["lzw"]
"lzw"
"none"
"packbits"
"deflate"
"logluv"(24)
- LogLuv compression, perfect for high dynamic range images. Expects floating point data as input. A limitation of this compression scheme is that the alpha channel cannot be stored in the same TIFF directory as the image, so it is written separatly in a 2nd directory. The white point is also stored in the TIFF when using this compression.
"string description" "s"
"string extratags" ["on"]
Tag name | Description |
