ReadFromImage(Stream,int) Method

Summary

Loads an embedded ICC profile from a stream.

Syntax

C++/CLI

Python

public void ReadFromImage( 
   Stream stream, 
   int pageNumber 
)

public: 
void ReadFromImage(  
   Stream^ stream, 
   int pageNumber 
)

def ReadFromImage(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.

Remarks

ICC profiles can be loaded from EPS, JPEG, PNG, PICT, PSD or TIFF 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.

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); 
}
