ReadFromImage(String,Int32) Method

public void ReadFromImage( 
   string fileName,
   int pageNumber
)

'Declaration
 
Public Overloads Sub ReadFromImage( _
   ByVal fileName As String, _
   ByVal pageNumber As Integer _
)

'Usage
 
Dim instance As IccProfileExtended
Dim fileName As String
Dim pageNumber As Integer
 
instance.ReadFromImage(fileName, pageNumber)

public:
void ReadFromImage( 
   String^ fileName,
   int pageNumber
)

Parameters

fileName: Character string containing the name of the file that contains the embedded ICC profile.
pageNumber: 1-based index of the page within the file that contains the ICC profile.

ICC profiles can be loaded from JPEG, TIFF, PSD or EPS files. For multipage files, you can save the profile to a particular page using the pageNumber parameter.
If the ICC profile loaded was version 4.0 or 4.2, its data will be extracted into the class members. Otherwise, the ICC profile is kept as one piece in the Data array.

This example loads an ICC profile that is embedded in an image, and saves it as a separate ICC profile file.
