| ResizeToFit |
0 |
Shrink the bitmap as necessary to fit, preserving its aspect ratio.
|
| BiggerSizeOk |
1 |
Passed by callers if they want to stretch the returned image themselves.
For example, if the caller passes an icon size of 80x80, a 96x96 thumbnail could be returned.
This action can be used as a performance optimization if the caller expects that they will need to stretch the image.
Note that the Shell implementation of IShellItemImageFactory performs a GDI stretch blit.
If the caller wants a higher quality image stretch than provided through that mechanism,
they should pass this flag and perform the stretch themselves.
|
| MemoryOnly |
2 |
Return the item only if it is already in memory. Do not access the disk even if the item is cached.
Note that this only returns an already-cached icon and can fall back to a per-class icon
if an item has a per-instance icon that has not been cached.
Retrieving a thumbnail, even if it is cached, always requires the disk to be accessed,
so GetImage(Size, IShellItemImageFactoryGetImageFlags, IntPtr) should not be called from the UI thread
without passing MemoryOnly.
|
| IconOnly |
4 |
Return only the icon, never the thumbnail.
|
| ThumbnailOnly |
8 |
Return only the thumbnail, never the icon.
Note that not all items have thumbnails,
so ThumbnailOnly will cause the method to fail in these cases.
|
| InCacheOnly |
16 |
Allows access to the disk, but only to retrieve a cached item.
This returns a cached thumbnail if it is available.
If no cached thumbnail is available, it returns a cached per-instance icon but does not extract a thumbnail or icon.
|
| CropToSquare |
32 |
If necessary, crop the bitmap to a square.
|
| WideThumbnails |
64 |
Stretch and crop the bitmap to a 0.7 aspect ratio.
|
| IconBackground |
128 |
If returning an icon, paint a background using the associated app's registered background color.
|
| ScaleUp |
256 |
If necessary, stretch the bitmap so that the height and width fit the given size.
