Supported image formats: BMP, JPG and GIF. The component has internal functions to increase/decrease brightness and contrast, zoom the image, copy/paste from clipboard. All these functions are executed by pressing the different buttons of the component's GUI. There are several methods to load / save / acquire an imge. Once the image is loaded, it is automatically displayed in the component's GUI.

All these functions are implemented in the TPictPreview component.
