![]() | Create(AtalaImage) | Creates a new thumbnail image from the supplied image. |
![]() | Create(Stream, Int32) | Creates a new thumbnail image from the supplied stream and frame index. |
![]() | Create(String, Int32) | Creates a new thumbnail image from the supplied file and frame index. |
![]() | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |

This class uses optimized image decoding and scaling to create a high quality thumbnail from a source image. It will used scaled loading when the source file is a JPEG, utilize scale to gray resampling when the source image is 1-bit with a document imaging license, and use area average otherwise.
This class can be conveniently used to generate thumbnail preview images.
note: when using DotImage Photo or Photo Pro, making a thumbnail out of a 1-bit image will take much more memory and be less efficient as it will convert to grayscale first, then resample the image.
