Image processing apparatus, image processing method, and recording medium

An image processing method executed by an image processing apparatus, including a host tool that provides a basic function of the image processing apparatus and a plurality of guest tools that each provide an extended function, the method comprising:

• receiving, sequentially, a plurality of processing information items each indicating a content of a user operation performed to generate or edit an object using corresponding to either the host tool or one of the plurality of guest tools;
• determining a particular tool from among the host tool and the plurality of guest tools corresponding to a currently received processing information item;
• registering the currently received processing information item of the determined particular tool in a particular processing list corresponding to the determined particular tool that was determined from among the host tool and the plurality of guest tools, each of the plurality of guest tools having a corresponding separate processing list and the host tool having a corresponding host processing list;
• setting a pointer to point to the currently received processing information item in the particular processing list, in response to receiving the currently received processing information item;
• and
• displaying a display image including the object generated by sequentially performing editing according to one or more of the received processing information items of the host tool or the plurality of guest tools.

A non-transitory recording medium which, when executed by circuitry of an image processing apparatus that includes a host tool that provides a basic function of the image processing apparatus and a plurality of guest tools that each provide an extended function, causes the circuitry to perform an image processing method comprising:

• receiving, sequentially, a plurality of processing information items, each indicating a content of a user operation performed to generate or edit an object using corresponding to either the host tool or one of the plurality of guest tools;
• determining a particular tool from among the host tool and the plurality of guest tools corresponding to a currently received processing information item;
• registering the currently received processing information item of the determined particular tool in a particular processing list corresponding to the determined particular tool that was determined from among the host tool and the plurality of guest tools, each of the plurality of guest tools having a corresponding separate processing list and the host tool having a corresponding host processing list;
• setting a pointer to point to the currently received processing information item in the particular processing list, in response to receiving the currently received processing information item;
• and
• displaying a display image including the object generated by sequentially performing editing according to one or more of the received processing information items of the host tool or the plurality of guest tools.
