 | m_fUniformAlpha | If all pixels of the image have the same alpha value, the field stores the alpha value as a number in the range [0, 1]. If the alpha value varies accross pixels, the value must be -1. If not calculated yet, the value must be -2. |
| m_ImageCacheLock | Image cache lock object. |
 | Mjdb | |
| njdb | |
| Ojdb |
| Name | Description | |
|---|---|---|
 | Bounds | Gets the image natural bounds. |
| DataException | Gets the exception that has been thrown during retrieval of image source data. Returns null if no exception has been thrown. |
| FrameCount | Gets the number of frames in the image. |
| Height | Gets the height of this image source. |
| ImageInfo | Gets information about the current image data. |
| IsMutable | Returns true if the image source data can change during the lifetime of this image source. |
| Width | Gets the width of this image source. |
| Name | Description | |
|---|---|---|
 | CreateFrameRaster | Creates a raster for the frame at the given zero-based index. |
| CreateRaster | Creates a new raster from the native image data of this source. |
| DeepClone | Must override to create a copy of the current object. |
| Deserialize | Must override to deserialize the object state from the specified property bag. |
| GetEncodedData | Obtains encoded image data for this image source. |
| SafeCreateRaster | Creates a new raster from the native image data of this source. |
| Serialize | Must override to serialize the object state into the specified property bag. |
| TryGetUniformAlpha | Determines whether all of the image's pixels have the same alpha value and obtains this alpha value. |
| Name | Description | |
|---|---|---|
 | ClearCachedInfo | Clears the image source's cached data. |
| GetDescriptionPairs | |
 | GetFrameData | Returns image data that should be used for rendering of the image source's current frame. Encoded data is returned for encoded images sources with a single frame. Decoded data is returned for NRaster-based image sources and for encoded images sources with animated frames. |
| GetImmutableKey | Gets an immutable image source that can be used as a hash table key for this image source. If this image source is immutable it can return itself as a key. |
| GetNativeData | Gets the image source's image data in its native form. |
| OnImageDataChanged | Clears cached data and raises the ImageDataChanged event. |
 | pIdb | Overloaded. |
| SIdb | |
| tEn | |
| tIdb | |
| UpdateImageInfo | Updates the cached data of this image source. |
| vIdb |
