Resolve the ICC profile embedded in an image's own file, into an opaque container.
The export counterpart of dt_image_get_input_profile(): when an export names no output profile, the image's embedded one is used. Same ownership contract – the container knows whether it created the handle, so the caller does not.
| imgid | image whose embedded profile is wanted. |
| type | receives the profile type resolved. Must not be NULL. |

| ) |
Resolve an image's own input profile into an opaque container, whatever kind it is.
The six image-derived profile types (DT_COLORSPACE_EMBEDDED_ICC through DT_COLORSPACE_ALTERNATE_MATRIX) are the ones that are NOT in the application profile list and cannot be resolved by identity, because their matrices come from this one image's camera data. Three of them are built from the camera model, three from the file's own contents, and iop/colorin.c used to open-code the cascade between them – holding a raw cmsHPROFILE and a separate "did I create this one" flag it had to get right on every early return.
This resolves all six and hands back a container that carries the ownership answer with it, so a caller never decides whether to close a handle. Pass it straight to dt_colorspaces_prepare_conversion() as an endpoint's resolved field.
| imgid | image whose profile is wanted. |
| requested | one of the six image-derived types. Any other type returns NULL, since those are resolvable by identity and belong to the profile list. |
| camera_makermodel | the image's camera_makermodel, needed by the three built-from-the-camera types. May be NULL, which makes those three fail over to the embedded-ICC branch exactly as a missing matrix does. |
| resolved | if not NULL, receives the type actually resolved, which may differ from requested when a fallback fired (a camera with no matrix in the table, an image with no embedded ICC). Set to DT_COLORSPACE_NONE when NULL is returned. |
dt_colorspaces_free_image_profile(), or NULL when nothing could be resolved. The caller owns it and must outlive anything derived from it. Definition at line 482 of file imageio_profile.c.
