## Image class


A base class for [System::Drawing::Bitmap](../bitmap/) and System::Drawing::Metafile classes providing basic functionality. Objects of this class should only be allocated using [System::MakeObject()](../../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../../system/smartptr/) pointer and use this pointer to pass it to functions as argument.

```cpp
class Image : public virtual System::IDisposable
```

| [GetThumbnailImage](./getthumbnailimage/)(int, int, Image::GetThumbnailImageAbort, IntPtr) | Gets a thumbnail for this [System::Drawing::Image](./) object. |
| static [IsAlphaPixelFormat](./isalphapixelformat/)(Imaging::PixelFormat) | Determines if the specified pixel format contains alpha information. |
| virtual [IsMultiImage](./ismultiimage/)() const | Returns whether the original format is a multi-image. |
| virtual [RotateFlip](./rotateflip/)(RotateFlipType) | Rotate image to multiple of 90 degrees and flip. |
