// This example shows how to use Plugin functions to explore FreeImage capabilities.
|
|
// Whenever an external plugin is added to the library, it is automatically loaded
|
|
// with FreeImage and can be asked for its capabilities via the plugin functions.
|
|
//
|
|
// Functions used in this sample :
|
|
// FreeImage_FIFSupportsExportBPP, FreeImage_FIFSupportsICCProfiles, FreeImage_FIFSupportsReading,
|
|
// FreeImage_FIFSupportsWriting, FreeImage_GetFIFCount, FreeImage_GetFIFDescription,
|
|
// FreeImage_GetFIFExtensionList, FreeImage_GetFormatFromFIF,
|
|
// FreeImage_GetVersion, FreeImage_GetCopyrightMessage, FreeImage_SetOutputMessage
