'Declaration
 
Public Overloads Shared Sub ConvertColorSpace( _
   ByVal page As ImGearRasterPage, _
   ByVal newColorSpace As ImGearColorSpace, _
   ByVal sourceProfile As ImGearColorProfile, _

'Usage
 
Dim page As ImGearRasterPage
Dim newColorSpace As ImGearColorSpace

ImGearRasterProcessing.ConvertColorSpace(page, newColorSpace, sourceProfile, destinationProfile, renderingIntent)

public static void ConvertColorSpace( 
   ImGearRasterPage page,
   ImGearColorSpace newColorSpace,
   ImGearColorProfile sourceProfile,
   ImGearColorProfile destinationProfile,
   ImGearRenderingIntents renderingIntent
)

public: static void ConvertColorSpace( 
   ImGearRasterPage* page,
   ImGearColorSpace newColorSpace,
   ImGearColorProfile* sourceProfile,
   ImGearColorProfile* destinationProfile,
   ImGearRenderingIntents renderingIntent
)

public:
static void ConvertColorSpace( 
   ImGearRasterPage^ page,
   ImGearColorSpace newColorSpace,
   ImGearColorProfile^ sourceProfile,
   ImGearColorProfile^ destinationProfile,
   ImGearRenderingIntents renderingIntent
)

Parameters

page: Image to change color space.
newColorSpace: New color space.
sourceProfile: Initial color space profile.
destinationProfile: The new color space profile.
renderingIntent: Rendering intent.

Remarks

The image's pixel data is modified to conform to the new color space. This method does not concern itself with any of the settings of ImageGear.Core.ImGearColorProfileManager class. Instead, it allows immediate and explicit specification of color profiles to use for the conversion.

Example

// Load color profiles and convert an image from CMYK into RGB color space.

// Get the base path for the running executable.
string exePath = Assembly.GetExecutingAssembly().Location;
Int32 nIndex = exePath.LastIndexOf("\\");
exePath = exePath.Remove(nIndex + 1, exePath.Length - nIndex - 1);
// Read color profiles from the executable's path.
using (FileStream fs = File.OpenRead(exePath + "ig_cmyk_profile.icm"))
    ImGearColorProfileManager.CmykProfile = new ImGearColorProfile(fs);
using (FileStream fs = File.OpenRead(exePath + "ig_rgb_profile.icm"))
    ImGearColorProfileManager.RgbProfile = new ImGearColorProfile(fs);
// Convert an opened CMYK image into the RGB colorspace using ImageGear color profiles.
ImGearRasterProcessing.ConvertColorSpace(igRasterPage,
    new ImGearColorSpace(ImGearColorSpaceIDs.RGB), ImGearColorProfileManager.CmykProfile,
    ImGearColorProfileManager.RgbProfile, ImGearRenderingIntents.PERCEPTUAL);

Visual Basic

' Load color profiles and convert an image from CMYK into RGB color space.

' Get the base path for the running executable.
Dim exePath As String = Assembly.GetExecutingAssembly().Location
Dim nIndex As Int32 = exePath.LastIndexOf("\")
exePath = exePath.Remove(nIndex + 1, exePath.Length - nIndex - 1)
' Read color profiles from the executable's path.
Using fs As FileStream = File.OpenRead(exePath + "ig_cmyk_profile.icm")
    ImGearColorProfileManager.CmykProfile = New ImGearColorProfile(fs)
End Using
Using fs As FileStream = File.OpenRead(exePath + "ig_rgb_profile.icm")
    ImGearColorProfileManager.RgbProfile = New ImGearColorProfile(fs)
End Using
' Convert an opened CMYK image into the RGB colorspace using ImageGear color profiles.
ImGearRasterProcessing.ConvertColorSpace(igRasterPage, New ImGearColorSpace(ImGearColorSpaceIDs.RGB), _
 ImGearColorProfileManager.CmykProfile, ImGearColorProfileManager.RgbProfile, ImGearRenderingIntents.PERCEPTUAL)
