class ColorSpaceMenuParameters¶

Parameters controlling which color spaces appear in menus.

The ColorSpaceMenuHelper class is intended to be used by applications to get the list of items to show in color space menus.

The ColorSpaceMenuParameters class is used to configure the behavior as needed for any given menu. Here is the algorithm used to produce a list of “items” (or strings) that will appear in a menu:

1) Use setRole to identify a role that controls a given menu. If the config has this role, then only that color space is returned. The name is set to the color space name, the UIName is presented as “<role name> (<color space name>)”. It may be useful for the application to then grey-out the menu or otherwise indicate to the user that the value for this menu is not user selectable since it was pre-determined by the config. If the config does not have that role, the algorithm continues to the remaining steps.

2) The IncludeColorSpaces, SearchReferenceSpaceType, and IncludeNamedTransforms parameters are used to identify a set of items from the config that are potential candidates for use in the menu, as follows:

IncludeColorSpaces: Set to true to include color spaces in the menu.
SearchReferenceSpaceType: Use this to control whether the menu should include all color spaces, only display color spaces, or only non-display color spaces.
IncludeNamedTransforms: Set to true to include named transforms in the menu.

3) The set of items from step 2 is then filtered in step 3 using the following parameters:

AppCategories: A list of strings specified by the application based on the purpose of the menu. For example, if the menu is used to select a color space for importing an image, the application might specify the ‘file-io’ category, whereas if it is to select a working color space, it might specify the ‘working-space’ category. Application developers should document what strings they are using for each menu so that config authors know what categories to use in their configs. Alternatively, an application could let advanced users customize the string to use for a given menu in the application.
Encodings: A list of strings used to further refine the items selected from the AppCategories. For example, an application might specify ‘working-space’ as the category and then specify ‘scene-linear’ as the encoding to only use items that have both of those properties (e.g., only select scene-linear working color spaces).
UserCategories: A list of strings specified by the end-user of the application. OCIO will check for these strings in an environment variable, or they may be passed in from the application.
TreatNoCategoryAsAny: By default, color spaces (or named transforms) that have no categories are handled as if they had any of the categories. Config authors that want to hide color spaces without categories should either put them in the inactiveColorSpaces list or add a category that will never be searched for (e.g., “invisible” or “hidden”). App developers may set this option to false to hide items without any categories.

Basically the intent is for the filtering to return the intersection of the app categories, encoding, and user categories. However, some fall-backs are in place to ensure that the filtering does not remove all menu items. Here is the detailed description:

3a) The items from step 2 are filtered to generate a list of appItems containing only the ones that contain at least one of the AppCategories strings in their “categories” property and one of the encodings in their “encoding” property. If this list is empty, an attempt is made to generate a non-empty appItems list by only filtering by AppCategories. If that is empty, an attempt is made to only filter by Encodings.

3b) The items from step 2 are filtered to generate a list of userItems containing only the ones that have at least one of the UserCategories strings in their “categories” property.

3c) If both appItems and userItems are non-empty, a list of resultItems will be generated as the intersection of those two lists.

3d) If the resultItems list is empty, the appList will be expanded by only filtering by AppCategories and not encodings. The resultItems will be formed again as the intersection of the appItems and userItems.

3e) If the resultItems is still empty, it will be set to just the appItems from step 3a.

3f) If the resultItems is still empty, it will be set to just the userItems.

3g) If the resultItems is still empty, the items are not filtered and all items from step 2 are returned. The rationale is that if step 2 has produced any items, it is not acceptable for step 3 to remove all of them. An application usually expects to have a non-zero number of items to display in the menu. However, if step 2 produces no items (e.g. the application requests only named transforms and the config has no named transform), then no items will be returned.

4) If IncludeRoles is true, the items from step 3 are extended by including an item for each role. The name is set to the role name, the UIName is presented as “<role name> (<color

space name>)”, and the family is set to “Roles”.

5) If AddColorSpace has been used to add any additional items, these are appended to the final list.

std::ostream &OpenColorIO_v2_6dev::operator<<(std::ostream&, const ColorSpaceMenuParameters&)¶

class ColorSpaceMenuHelper¶

Helper class to create menus for the content of a config.

Menu can list color spaces, roles, named transforms. Each entry has a name, a UI name, a description, and a family. Family can also be accessed as hierarchy levels; levels are created by splitting the family using the ‘family separator’. Hierarchy levels are meant to be used as sub-menus.

The UI name is what is intended to be put in application menus seen by the end-user. However, please note that the UI name is not guaranteed to remain stable between releases and so if applications need to save something it should be the ‘name’ rather than the ‘UI name’. Currently, the only difference between the ‘name’ and ‘UI name’ is for roles.

The overall ordering of items is: color spaces, named transforms, roles, and additional color spaces. The display color spaces will either come before or after the other color spaces based on where that block of spaces appears in the config. The order of items returned by the menu helper preserves the order of items in the config itself for each type of elements, thus preserving the intent of the config author. For example, if you call getName at idx and idx+1, the name returned at idx+1 will be from farther down in the config than the one at idx as long as both are of the same type. (An application may ask for only the items in one of those blocks if it wants to handle them separately.) If the application makes use of hierarchical menus, that will obviously impose a different order on what the user sees in the menu. Though even with hierarchical menus, applications should try to preserve config ordering (which is equivalent to index ordering) for items within the same sub-menu.

class LegacyViewingPipeline¶

Whereas the DisplayViewTransform simply applies a specific view from an OCIO display, the LegacyViewingPipeline provides an example of a complete viewing pipeline of the sort that could be used to implement a viewport in a typical application. It therefore adds, around the DisplayViewTransform, various optional color correction steps and RGBA channel view swizzling. The direction of the DisplayViewTranform is used as the direction of the pipeline. Note: The LegacyViewingPipeline class provides the same functionality as the OCIO v1 DisplayTransform.

Legacy viewing pipeline:

Start in display transform input color space.
If linearCC is provided:
- Go to scene_linear colorspace.
- Apply linearCC transform.
If colorTimingCC is provided:
- Go to color_timing colorspace.
- Apply colorTimingCC transform.
Apply looks (from display transform or from looks override).
- Go to first look color space.
- Apply first look transform.
- Iterate for all looks.
Apply channelView transform.
Apply display transform (without looks).
Apply displayCC. Note that looks are applied even if the display transform involves data color spaces.

virtual void setLooksOverride(const char *looks) = 0¶

A user can optionally override the looks that are, by default, used with the expected display / view combination. A common use case for this functionality is in an image viewing app, where per-shot looks are supported. If for some reason a per-shot look is not defined for the current Context, the Config::getProcessor fcn will not succeed by default. Thus, with this mechanism the viewing app could override to looks = “”, and this will allow image display to continue (though hopefully) the interface would reflect this fallback option.

Looks is a potentially comma (or colon) delimited list of lookNames, where +/- prefixes are optionally allowed to denote forward/inverse look specification (and forward is assumed in the absence of either).

class MixingSlider¶

The MixingSlider and MixingColorSpaceManager classes are to help applications implement correct color pickers. The term “color mixing” is used here to describe what is done in a typical application “color picker” user interface.

A user may want to mix colors in different color spaces. The two most common mixing space options are a scene-linear working space or the display space.

Since scene-linear color spaces are not perceptually uniform, it is necessary to compensate UI widgets such as sliders. For example, it is nice if mid-gray falls near the center of mixing controls rather than way over near the black end. This may be done by using a mapping from linear into an approximately perceptually uniform space.

Also note that a color picking/mixing UI may want to present a given color space in several different encodings. The most common two encodings for color mixing are RGB and HSV.

Note that these helpers anticipate that a user may want to mix colors using values that extend outside the typical [0,1] domain.
