Returns or sets whether the feature of disk caching is enabled.
.IfAllowLocalCache = true;
The default value of IfAllowLocalCache is true. When the property is true, you can scan as many images as you want as long as you have a big enough disk.
The default threshold is set to 800 (MB), anything beyond 800MB gets compressed, encrypted and cached on the local disk. If necessary, you can set the threshold using
BufferMemoryLimit for better performance.
All cached data is encrypted and can only be read by Dynamic Web TWAIN and it will be destroyed when it is no longer used.
