## Abstract

This article relates to a definition of a image manipulation command set which is so flexible that sequence of transformation operations (e.g., rotation, scaling) in any combination or number can be specified on a specific part of a source image. This is possible since the sequence of the transformation operations is defined as the operations on images inside a logical space which is separate from the source image. An image manipulation command such as rotation of the current image manipulation command set means the process to extract part or all of the source image, to apply the transformation operation, and finally to write the result back to the source. It is not possible to specify a sequence of transformation operations on the same part or all of the source image by a sequence of commands out of this kind of command set.

Flexible Image Editing Command Set Using a Logical Space Separate From the Source Image

This article relates to a definition of a image manipulation command set which is so flexible that sequence of transformation operations (e.g., rotation, scaling) in any combination or number can be specified on a specific part of a source image. This is possible since the sequence of the transformation operations is defined as the operations on images inside a logical space which is separate from the source image. An image manipulation command such as rotation of the current image manipulation command set means the process to extract part or all of the source image, to apply the transformation operation, and finally to write the result back to the source. It is not possible to specify a sequence of transformation operations on the same part or all of the source image by a sequence of commands out of this kind of command set. Since the source image is changed at the execution of each command, a command in the sequence is applied on the source image which was already written by the previous command execution. A new image manipulation command set can solve the above deficiency by separating the process of extraction, transformation and writing and by assigning separate commands, EXTRACT, transformations and WRITE for each process, respectively. Semantics of EXTRACT command is to extract a part or all of the source image and put it in the Extracted Image Space (EIS) which is a lo...
