### Functions (67)

#### ACApplyTransform

```cpp
AC_Error ACApplyTransform(AC_Transform transform, const void *srcData, void *dstData, ASUns32 count, AC_PackingCode srcPacking, AC_PackingCode dstPacking)
```

Header: `AcroColorProcs.h:741`

Applies a color conversion or gamut test transformation. It processes the number of colors specified by `count`, using the memory formats for the source and destination data specified in `srcPacking` and `dstPacking`. The source data and destination data can point to the same block of memory if the source and destination packing formats use the same number of bits per color.

**Parameters**

If both ASCII and Unicode data are specified, the AC_String object keeps track of both in parallel, returning the ASCII data when asked for ASCII, and the Unicode data when asked for Unicode. These dual-encoded strings are useful as description strings for ICC profiles, which can store both ASCII and Unicode data in their description tags. The ICC profile standard requires that the ASCII version of the description string be limited to 7-bit ASCII characters. The AcroColor engine requires only the Unicode descriptions to be unique among profile descriptions.

**Parameters**

#### ACProfileFromDescription

```cpp
AC_Error ACProfileFromDescription(AC_Profile *profile, AC_String description)
```

Header: `AcroColorProcs.h:475`

Finds a profile matching the description string in the database. The client should call ACUnReferenceProfile() when done with the profile. • If the description string contains Unicode text, the Unicode text is used to find the profile. • If the description string contains only ASCII text, the method tries to find a match. However, the AcroColor engine requires only Unicode descriptions to be unique, so this might return the wrong profile is in some rare cases. Use ASCII-only description strings only when Unicode description string are unavailable.

**Parameters**

- `profile` ([`AC_Profile *`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/acrocolor.md#AC_Profile)): (Filled by the method) A pointer to the device color profile object.

AC_Error ACProfileListItemCode(AC_ProfileList list, ASUns32 index, AC_ProfileCode *code)
```

Header: `AcroColorProcs.h:164`

Gets the profile code of a specified profile in a profile list. While this routine is not absolutely required, since the description string is always a unique reference, profile codes have the advantage that they are localization-independent.

**Parameters**

- `list` ([`AC_ProfileList`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/acrocolor.md#AC_ProfileList)): The profile list.

```cpp
AC_Error ACProfileListItemDescription(AC_ProfileList list, ASUns32 index, AC_String *description)
```

Header: `AcroColorProcs.h:145`

Returns the description string of a specified profile in a list. The returned description string always contains both ASCII and Unicode data, even if the profile itself only contains an ASCII version. You can store only the Unicode data in settings files if you wish; the ACProfileFromDescription() method finds the correct profile when passed the Unicode-only string.

**Parameters**

- `list` ([`AC_ProfileList`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/acrocolor.md#AC_ProfileList)): The profile list.

```cpp
AC_Error ACProfilesMatch(AC_Profile workingProfile, AC_Profile documentProfile, ASBool *match)
```

Header: `AcroColorProcs.h:922`

Compares the working device profile with the document device profile to determine if they are the same. This comparison ignores rendering intents, and is *fuzzy*, allowing very close, but not exactly the same, profiles to match. Equivalent profiles always match, but some non-equivalent profiles may also match.

**Parameters**

- `workingProfile` ([`AC_Profile`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/acrocolor.md#AC_Profile)): The working device color profile.

#### ACSetBlackPointCompensation

```cpp
AC_Error ACSetBlackPointCompensation(ASUns32 bpc)
```

Header: `AcroColorProcs.h:1149`

Sets the black-point compensation flag, which controls whether to adjust for differences in black points when converting colors between color spaces. When enabled, the full dynamic range of the source space is mapped into the full dynamic range of the destination space. When disabled, the dynamic range of the source space is simulated in the destination space (which can result in blocked or gray shadows).

**Parameters**

- `bpc` ([`ASUns32`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/aslayer.md#ASUns32)): `1` to enable black-point compensation, `0` otherwise.

**Returns:** [`AC_Error`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/acrocolor.md#AC_Error)

`0` if successful, a non-zero error code otherwise.

#### ACSetEngine

```cpp
AC_Error ACSetEngine(ASUns32 cmsID, ASUns32 cmmID)
```

Header: `AcroColorProcs.h:87`

Sets the AcroColor engine (ACE) for the system, changing the global default CMS/CMM choice. This method rebuilds all existing transforms using the new engine. If the user aborts the process, or if the ACE runs out of resources during the rebuilding process, an error code is returned and some existing transforms may still use the previous engine choice. Everything will still work, since multiple engines can be used at once. Call the method again to restart the transform rebuilding process.

**Parameters**

- `cmsID` ([`ASUns32`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/aslayer.md#ASUns32)): The Color Management System identifier for the new engine default, as returned by ACEngineInfo().

#### ACStringASCII

```cpp
AC_Error ACStringASCII(AC_String string, char *buffer, ASUns32 *count, ASUns32 maxCount)
```

Header: `AcroColorProcs.h:820`

Copies the ASCII version of a string into a supplied buffer. Either the `buffer` or the `count` can be `NULL`. The ICC profile standard requires that ASCII version of the profile description string be limited to 7-bit ASCII characters. Depending on the API, operating system, file contents, and so on, the method can return strings in the local script code (8 bit single byte or 8 bit encoded multi-byte). Clients should always assume that the ASCII data is in the local script code (of which the 7-bit ASCII characters are a subset).

**Parameters**

- `string` ([`AC_String`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/acrocolor.md#AC_String)): The AcroColor string containing ASCII data. If the string does not contain an ASCII version, the method returns AC_Error_NoASCII.
- `buffer` (`char *`): (Filled by the method) A buffer to contain a copy of the ASCII data.
- `count` ([`ASUns32 *`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/aslayer.md#ASUns32)): (Filled by the method) A pointer to the size of `buffer` in bytes, including the trailing `NULL` character.
- `maxCount` ([`ASUns32`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/aslayer.md#ASUns32)): The maximum size of `buffer` in bytes. If the length of the string is longer than this value, the method copies a truncated string to the `buffer` and returns AC_Error_StringOverflow.

**Returns:** [`AC_Error`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/acrocolor.md#AC_Error)

`0` if successful, a non-zero error code otherwise.

#### ACStringLocalized

```cpp
AC_Error ACStringLocalized(AC_String string, ASUTF16Val *buffer, ASUns32 *count, ASUns32 maxCount)
```

Header: `AcroColorProcs.h:854`

Copies the localized Unicode version of a string into a supplied buffer. Either the `buffer` or the `count` can be `NULL`. The settings file format and ICC profiles later than version 2 can contain text in multiple languages or countries. When the AcroColor engine (ACE) create strings from these files or profiles, it uses the current language and country codes to create strings with a third fork: a localized Unicode version. These localized versions are intended for user display only and should not be stored in preferences files or action scripts, since they vary from country to country and are not portable.

**Parameters**

- `string` ([`AC_String`](https://docs.datalogics.com/apdfl21/AdobeCPlusCPlus/APDFL21.0.0PlusP1e/acrocolor.md#AC_String)): The AcroColor string containing localized Unicode data. If the string does not contain a localized Unicode version, the method returns AC_Error_NoLocalized.

#### AC_RenderIntent

Header: `AcroColorExpT.h:673`

Constants that specify a standard ICC rendering intent for a device color profile. The rendering intent specifies the color translation method for colors that are outside the gamut of the color profile.

**Values**

- `AC_Perceptual = 0`: Tries to preserve the visual relationship between colors in a way that is perceived as natural to the human eye, although the color values themselves may change. This is the same as the Image intent in Adobe PageMaker and Illustrator. This option is suitable for photographic, continuous tone images.
- `AC_RelColorimetric = 1`: The same as absolute colorimetric, except that it compares the white point of the source color space to that of the destination color space and shifts all other colors accordingly, rather than comparing individual colors.
- `AC_Saturation = 2`: Tries to create vivid color at the expense of accurate color. It scales the source gamut to the destination gamut, but preserves relative saturation instead of hue, so that when scaling to a smaller gamut, hues may shift. This is the same as the Graphics intent in Adobe PageMaker and Illustrator. This option is suitable for business graphics and charts, where the exact relationship between colors is not as important as having bright saturated colors.
- `AC_AbsColorimetric = 3`: Tries to maintain color accuracy at the expense of preserving relationships between colors. It leaves colors that fall inside the destination gamut unchanged. When translating to a smaller gamut, two colors that are distinct in the source space may be mapped to the same color in the destination space.
