**Namespace:** [Aurigma.GraphicsMill.Codecs](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_Codecs.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

```
 
## Members

|   |  Member name |  Description |
| --- | --- | --- |
 |   |  Thumbnail |  Resized bitmap (thumbnail). |
 |   |  Bitmap |  Original bitmap. |
 
## Remarks
  
Depending on these values, the [LoadFrameBitmap()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_CustomFormatReader_LoadFrameBitmap.htm.md) method should either load full bitmap from the file, or resize it on the fly. If the image should be resized, you can determine thumbnail size using the [GetThumbnailWidthToLoad()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_CustomFormatReader_GetThumbnailWidthToLoad.htm.md) and [GetThumbnailHeightToLoad()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_CustomFormatReader_GetThumbnailHeightToLoad.htm.md) methods.
