isicc

Return true for valid ICC color profile

Syntax

```
TF = isicc(P)
```

Description

TF = isicc(P) returns True if structure P is a valid ICC color profile; otherwise False.

isicc checks if P has a complete set of the tags required for an ICC profile. P must contain a Header field, which in turn must contain a Version field and a DeviceClass field. These fields, and others, are used to determine the set of required tags according to the ICC Profile Specification, either Version 2 (ICC.1:2001-04) or Version 4 (ICC.1:2001-12), which are available at www.color.org. The set of required tags is given in Section 6.3 in either version.

Example

Read in a profile and test its validity.

P = iccread('sRGB.icm');

TF = isicc(P)

TF =

   1

Create a MATLAB structure and test its validity.

S.name = 'Any Student';
S.score = 83;
S.grade = 'B+'

TF = isicc(S)

TF =

     0
