Graphics and image processing for debugging for a printing

A system, comprising:

• a printing device having:
• a memory configured to store program code;
• and
• a printer engine coupled to the memory having a graphic execution unit;
• wherein, in response to executing the program code, the printing device is configured to initiate operations for implementing graphics and image processing, including:
• obtaining a graphics orderlist by the printer engine, wherein the graphics orderlist has at least one imaging issue for printing an associated image on a print media;
• entering a debug mode for debugging the graphics orderlist;
• receiving a selection for a debug region having the at least one imaging issue;
• the receiving of the selection including conversion of a user screen-related input into a set of parameters associated with the debug region;
• executing a graphic order of the graphics orderlist by the graphic execution unit of the printer engine in the debug mode;
• determining by the graphic execution unit whether the debug region is accessed by the execution of the graphic order;
• and
• responsive to the debug region being accessed for the execution of the graphic order,
• issuing an interrupt at an end of the graphic order;
• and
• storing information of the graphic order and buffer contents associated with the debug region in a log file;
• wherein the at least one imaging issue is an imaging artifact in the image in an embedded system space of the printer engine which is not present in the image rendered in an operating system space.

A method for graphics and image processing, comprising:

• obtaining a graphics orderlist by a printer engine, wherein the graphics orderlist has at least one imaging issue for printing an associated image;
• entering a debug mode for debugging the graphics orderlist;
• receiving a selection for a debug region;
• executing a graphic order of the graphics orderlist by a graphic execution unit of the printer engine in the debug mode;
• determining by the graphic execution unit whether the debug region is accessed by the execution of the graphic order;
• responsive to the debug region being accessed for the execution of the graphic order,
• issuing an interrupt;
• and
• storing information of the graphic order and buffer contents associated with the debug region in a log file;
• wherein the determining by the graphic execution unit whether the debug region is accessed by the executing of the graphic order includes a read access or a write access of the debug region;
• wherein the selection includes conversion of user screen-related input into a set of parameters associated with the debug region;
• and
• dividing each page of a print job into multiple bands;
• wherein the set of parameters includes a page number, a band number, and x and y beginning and ending coordinates of the debug region for a sub-height and a sub-width of a band associated with the band number.
