Image Encryption
| ImageGear Professional v18.2 > User Guide > Using ImageGear > Processing Images > Image Encryption |
ImageGear provides a pair of image processing functions that perform image encryption/decryption operations. These functions change the image bitmap, modifying the format of the pixel data stored within it.
| IG_IP_encrypt() | Encrypts the image bitmap using the specified password string. To successfully decrypt the image bitmap, the specified password will be needed. |
| IG_IP_decrypt() | Decrypts an image bitmap using the password string specified during encryption. If the password is the same as used with IG_IP_encrypt(), then the decryption will be successful, and the original image bitmap will be restored. |
