A raster image conversion device is inputted with printing data and converts this printing data into raster image data to be outputted to a printing device. A storage unit stores printing environment data stipulating conditions for converting the printing data into the raster image data. An operating unit sets or edits the printing environment data. A conversion processing unit converts the printing data into the raster image data, based on the printing environment data. The printing environment data includes printing template information having a plurality of printing slots. The operating unit comprises an operating mode enabling the printing template information to be generated or edited. The conversion processing unit is inputted with or creates printing data made up of a plurality of pages, and, based on the printing template information, allocates a printing position and printing range of each page of the printing data to the printing slots.

Provided is an image processing apparatus that improves the performance when performing image processing accompanying an analysis. An image acquisition unit acquires processing image data for performing processing. A normal image processing unit performs normal image processing for normal output on the processing image data acquired by the image acquisition unit and outputs the normal image data. An analysis image processing unit performs analysis image processing accompanied by analysis in parallel with the normal image processing by the normal image processing unit and outputs the analysis image data. A merge processing unit merges the normal image data output by the normal image processing unit and the analysis image data output by the analysis image processing unit and outputs print data for printing.

A print data editing device performs editing print data such that when dots constituting an input image represented by the print data are compared by units of columns before and after performing the editing, a coincidence is maximized when an image of each column in the input image after the editing is the same position as an image of the corresponding column in the input image before the editing or is shifted by a corresponding shift amount relative to the image of the corresponding column in the input image before the editing and an editing condition is met. The editing condition includes that an absolute value of at least one shift amount is one dot or greater, an absolute difference value for any two neighboring columns is one dot or less, and at least one absolute difference value for all possible combinations of two columns is less than one dot.

A print data editing device is configured to perform: editing print data such that when dots constituting an input image represented by the print data are compared by units of columns before and after the editing, a coincidence is maximized when an image of each column in the input image after the editing is the same position as an image of the corresponding column in the input image before the editing or is shifted by a corresponding shift amount in a sub-scanning direction relative to the image of the corresponding column in the input image before the editing. An absolute value of at least one of shift amounts for columns in the input image after the editing is one dot or greater. An absolute difference value for any two neighboring columns in a main scanning direction in the input image after the editing is one dot or less.

An image forming apparatus can inhibit occurrence of defective images caused when a buffer consumption amount in sector correction exceeds a previously estimated capacity. The image forming apparatus comprises a line buffer for temporarily storing image data. The image forming apparatus performs correction processing of the image data to correct distortion of the image to store the corrected image data in the line buffer. Further, the image forming apparatus forms images on a recording medium based on the image data having experienced the correction processing. The CPU of the image forming apparatus determines whether a size of the image data having experienced the distortion correction by a first correction value based on a sector correction seed value exceeds the number of lines in the line buffer. If it is determined that it exceeds the number of lines, the CPU obtains a second correction value, correcting the first value.

In one aspect, the present disclosure relates to decorating and printing of edible media sheets based on a user-uploaded image. Using a browser-based user interface, the user selected image can be edited and embellished as an edible media design. The edible media design is converted to print data to enable printing of the edible media design using a printer installed with edible ink.

An image processing system for executing a plurality of processes includes a process execution control apparatus, and image generation-output control apparatuses of different types. The process execution control apparatus includes a process execution controller to control the processes, and to transmit a command information to the image generation-output control apparatuses. Each of the image generation-output control apparatuses includes a command information converter to convert the command information to a format processable by the image generation-output control apparatus, an imposition convertor to convert initial designation information to imposition process information processable by the image generation-output control apparatus, and an image drawing information generator to generate image drawing information.

A method and system for rendering rectangle drawing objects using a clip region are provided. For at least a first rectangle drawing object and a second rectangle drawing object, a determination is made if the first rectangle drawing object and the second rectangle drawing object satisfy a predetermined condition. If the predetermined condition is satisfied, one-line raster image data associated with the first and second rectangle drawing objects is generated, and a clip region corresponding to the first and second rectangle drawing objects is generated. Subsequently, the one-line raster image data may be used together with the clip region to fill a clipped drawing region corresponding to the first and second rectangle drawing objects.
