JPEG 2000 is an image coding system and state-of-the-art image compression standard. It uses wavelet technology to code lossless content in any quality at once. Moreover, without any substantial penalty in coding efficiency, JPEG 2000 has the capability to access and decode the same content efficaciously into a variety of other resolutions and qualities. The code streams in JPEG 2000 are significantly scalable having regions of interest that provide the facility for spatial random access.
Files with XLSM extension is a type of Spreasheet files that support Macros. From application point of view, a Macro is set of instructions that are used for automating processes. A macro is used to record the steps that are performed repeatedly and facilitates performing the actions by running the macro again.
