OpenImageIOReader

Utility node which reads image files from disk using OpenImageIO. All file types supported by OpenImageIO are supported by the OpenImageIOReader.

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

out

The output image generated by this node.

enabled

Turns the node on and off.

fileName

The name of the file to be read. File sequences with arbitrary padding may be specified using the ‘#’ character as a placeholder for the frame numbers. If this file sequence format is used, then missingFrameMode will be activated.

Supported file extensions : bmp, dib, cin, dds, dpx, fits, hdr, rgbe, ico, iff, z, jpg, jpe, jpeg, jif, jfif, jfi, jp2, j2k, j2c, null, nul, exr, sxr, mxr, png, ppm, pgm, pbm, pnm, pfm, psd, pdd, psb, bay, bmq, cr2, crw, cs1, dc2, dcr, dng, erf, fff, k25, kdc, mdc, mos, mrw, nef, orf, pef, pxn, raf, raw, rdc, sr2, srf, x3f, arw, 3fr, cine, ia, kc2, mef, nrw, qtk, rw2, sti, rwl, srw, drf, dsc, ptx, cap, iiq, rwz, cr3, rla, sgi, rgb, rgba, bw, int, inta, socket, pic, tif, tiff, tx, env, sm, vsm, tga, tpic, term, zfile, osl, oso, oslgroup, oslbody

refreshCount

May be incremented to force a reload if the file has changed on disk - otherwise old contents may still be loaded via Gaffer’s cache.

missingFrameMode

Determines how missing frames are handled when the input fileName is a file sequence (uses the ‘#’ character). The default behaviour is to throw an exception, but it can also hold the last valid frame in the sequence, or return a black image which matches the data window and display window of the previous valid frame in the sequence.

availableFrames

An output of the available frames for the given file sequence. Returns an empty vector when the input fileName is not a file sequence, even if it has a file-sequence-like structure.

channelInterpretation

Documented in ImageReader, where it is exposed to users.
