イメージに対する ICC プロファイル

PDFlib で、イメージに ICC プロファイルを適用するサンプルプログラムです。

RGB イメージをインポートして "sRGB" ICC プロファイルを適用します。CMYK イメージをインポートして、"ISOcoated" ICC プロファイルを適用します。

 * ICC profile to image:
 * Assign an ICC profile to an image
 * 
 * Apply the "sRGB" ICC profile to an imported RGB image.
 * Apply the "ISOcoated" ICC profile to an imported CMYK image.
 *
 *
 * Required software: PDFlib/PDFlib+PDI/PPS 9
 * Required data: RGB image file, CMYK image file, ICC profile
