OpenFX image processing plug-in API

This is the latest release of OFX, the Open Effects image-processing plug-in standard API.

Documentation and more info can be found at:

Release Notes

This is version 1.4 of the OFX API. Significant additions include a Dialog Suite for plugins to request the host to allow them to put up a modal dialog, a NativeOrigin host property, draft render quality support, half-float format tag available for CPU rendering (not just OpenGL), and a new internationalizable version of the progress suite.

A number of ambiguities in the spec have also been clarified in this version, including allowing OpenGL processing and tiled rendering to be enabled/disabled in Instance Changed events, and clarifying the semantics of dialogs and the progress suite. The old Analysis pass action has also been removed.

Deprecations

In this release, some old properties and tags which were deprecated in previous releases have now been moved to a new header file, include/oldOfx.h. To continue to support those old tags, whether as a plugin or a host, you'll need to include oldOfx.h.

Detailed List of Changes

  • removed = final stage of deprecation: moved to oldOfx.h
  • added = new property or tag
  • refined/modified = documentation of precise expectations (without touching definitions) also: some prototypes add a const

ofxImageEffects.h :

  • removed - kOfxImageEffectPropInAnalysis
  • removed - kOfxImageComponentYUVA
  • added - kOfxImageEffectPropRenderQualityDraft
  • refined - kOfxImageEffectPropSupportsTiles
  • added - kOfxImageEffectHostPropNativeOrigin
  • refined - kOfxImageEffectPropRenderScale (Interact action was missing in supported actions)
  • refined - prop kOfxBitDepthHalf (kOfxImageEffectPropPixelDepth)
  • refined - prop kOfxBitDepthHalf (kOfxImageClipPropUnmappedPixelDepth)
  • refined - prop kOfxBitDepthHalf (kOfxImageEffectPropSupportedPixelDepths)

ofxParam.h:

  • removed - kOfxParamPropPluginMayWrite
  • removed - kOfxParamDoubleTypeNormalisedX
  • removed - kOfxParamDoubleTypeNormalisedY
  • removed - kOfxParamDoubleTypeNormalisedXAbsolute
  • removed - kOfxParamDoubleTypeNormalisedYAbsolute
  • removed - kOfxParamDoubleTypeNormalisedXY
  • removed - kOfxParamDoubleTypeNormalisedXYAbsolute
  • modified - kOfxParamPropInteractMinimumSize is now a double (matches kOfxParamPropInteractSize)
  • modified - changed comments with regards to OfxParameterSuiteV1 (i.e. no Analysis action anymore)
  • refined - paramGetValue, paramSetValue: precision about when it's safe to use - i.e. Instance Changed domain only)

ofxPixels.h:

  • removed - OfxYUVAColourB;OfxYUVAColourS;OfxYUVAColourF // leftover from 1.2 deprecation
  • modified - OfxRGBColourD should not have an "a" component

  • added - OfxProgressSuiteV2

ofxDialog.h: NEW

  • added - OfxDialogSuiteV1

ofxOpenGLRender.h:

  • refined - kOfxImageEffectPropOpenGLRenderSupported

ofxCore.h:

  • modified - kOfxFlagInfiniteMax (INT_MAX) (and Min)
  • added - kOfxBitDepthHalf

ofxInteract.h:

  • removed - kOfxInteractPropViewportSize

ofxOld.h:

  • New file added to capture removals ("removed" above)

/Support folder:

  • C++ wrapper adds support for v1.3 and v1.4
