RemarksThis 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.
