ImageHasIccProfile(Stream,int) Method

Summary

Determines whether a stream has an embedded ICC profile.

Syntax

C++/CLI

Python

public static bool ImageHasIccProfile( 
   Stream stream, 
   int pageNumber 
)

public: 
static bool ImageHasIccProfile(  
   Stream^ stream, 
   int pageNumber 
)

def ImageHasIccProfile(self,stream,pageNumber):

Parameters

stream
The stream containing the ICC profile.

pageNumber
1-based index of the page within the file that contains the ICC profile.

Return Value

true if this stream has an embedded ICC Profile; false, if it does not.

Remarks

EPS, JPEG, PNG, PICT, PSD, and TIFF files can have ICC profiles. To check the profile of a specific page in a multipage stream, use the pageNumber parameter.

Example

using Leadtools; 
using Leadtools.ColorConversion; 
 
using Leadtools.Codecs; 
 
public string IccfileName = Path.Combine(LEAD_VARS.ImagesDir, "ColorConversion", "ReadFromImage.icc"); 
 
public void ReadFromImageExample() 
{ 
   // Create an ICC profile object 
   IccProfileExtended iccProfile = new IccProfileExtended(); 
 
   // Load the ICC from an image, by specifying the image's name, and the 1-based page number that contains the ICC. 
   // To load the ICC from an Image that is in a stream, put the stream instead of the file name 
   string fileName = Path.Combine(LEAD_VARS.ImagesDir, "ColorConversion", "11800-Embedded_RGB.png"); 
 
   // If image has ICC profile then load it 
   if (IccProfileExtended.ImageHasIccProfile(fileName, 1)) 
      iccProfile.ReadFromImage(fileName, 1); 
   else 
      throw new Exception("ICC Profile not found"); 
 
   // At this point, the iccProfile object contains the ICC profile that was found in the image 
   // For this example, save it in a seperate ICC profile file 
   // Generate the profileId. For the time being, it will be filled with 0's 
   iccProfile.GenerateProfileId(); 
 
   // Generate the new ICC profile by updating the Data Array and then generating the file 
   iccProfile.UpdateDataArray(); 
   iccProfile.GenerateIccFile(IccfileName); 
}
