NAME
oiiotool - the OIIO Swiss Army Knife SYNOPSIS
oiiotool [filename|option|action]... DESCRIPTION
The oiiotool program will read images (from any file format for which an ImageInput plugin can be found), perform various operations on them, and write images (in any format for which an ImageOutput plugin can be found). The oiiotool utility is invoked as follows: oiiotool args oiiotool maintains an image stack, with the top image in the stack also called the current image. The stack begins containing no images. oiiotool arguments consist of image names, or commands. When an image name is encountered, that image is pushed on the stack and becomes the new current image. Most other commands either alter the current image (replacing it with the alteration), or in some cases will pull more than one image off the stack (such as the current image and the next item on the stack) and then push a new image. For a complete description, see /usr/share/doc/libopenimageio-dev/openimageio.pdf.gz. OPTIONS
Options (general): --help Print help message -v Verbose status messages -q Quiet mode (turn verbose off) -a Do operations on all subimages/miplevels --info Print resolution and metadata on all inputs --stats Print pixel statistics on all inputs --hash Print SHA-1 hash of each input image --no-clobber Do not overwrite existing files --threads %d Number of threads (default 0 == #cores) Commands that write images: -o %s Output the current image to the named file Options that affect subsequent image output: -d %s Set the output data format to one of: uint8, sint8, uint10, uint12, uint16, sint16, half, float, double --scanline Output scanline images --tile %d %d Output tiled images (tilewidth, tileheight) --compression %s Set the compression method --quality %d Set the compression quality, 1-100 --planarconfig %s Force planarconfig (contig, separate, default) --adjust-time Adjust file times to match DateTime metadata --noautocrop Do not automatically crop images whose formats don't support separate pixel data and full/display windows Options that change current image metadata (but not pixel values): --attrib %s %s Sets metadata attribute (name, value) --sattrib %s %s Sets string metadata attribute (name, value) --caption %s Sets caption (ImageDescription metadata) --keyword %s Add a keyword --clear-keywords Clear all keywords --orientation %d Set the assumed orientation --rotcw Rotate orientation 90 deg clockwise --rotccw Rotate orientation 90 deg counter-clockwise --rot180 Rotate orientation 180 deg --origin %s Set the pixel data window origin (e.g. +20+10) --fullsize %s Set the display window (e.g., 1920x1080, 1024x768+100+0, -20-30) --fullpixels Set the 'full' image range to be the pixel data window Options that affect subsequent actions: --fail %g Failure threshold difference (0.000001) --failpercent %g Allow this percentage of failures in diff (0) --hardfail %g Fail diff if any one pixel exceeds this error (infinity) --warn %g Warning threshold difference (0.00001) --warnpercent %g Allow this percentage of warnings in diff (0) --hardwarn %g Warn if any one pixel difference exceeds this error (infinity) Actions: --create %s %d Create a blank image (args: geom, channels) --pattern %s %s %d Create a patterned image (args: pattern, geom, channels) --unmip Discard all but the top level of a MIPmap --selectmip %d Select just one MIP level (0 = highest res) --subimage %d Select just one subimage --diff Print report on the difference of two images (modified by --fail, --failpercent, --hardfail, --warn, --warnpercent --hardwarn) --add Add two images --sub Subtract two images --abs Take the absolute value of the image pixels --flip Flip the image vertically (top<->bottom) --flop Flop the image horizontally (left<->right) --flipflop Flip and flop the image (180 degree rotation) --crop %s Set pixel data resolution and offset, cropping or padding if necessary (WxH+X+Y or xmin,ymin,xmax,ymax) --croptofull Crop or pad to make pixel data region match the "full" region --resize %s Resize (640x480, 50%) --fixnan %s Fix NaN/Inf values in the image (options: none, black, box3) --pop Throw away the current image --dup Duplicate the current image (push a copy onto the stack) Color management: --iscolorspace %s Set the assumed color space (without altering pixels) --tocolorspace %s Convert the current image's pixels to a named color space --colorconvert %s %s Convert pixels from 'src' to 'dst' color space (without regard to its previous interpretation) Known color spaces: "linear", "sRGB", "Rec709" SEE ALSO
