Abstract
Defect-free printing is achieved by previewing on a display prior to printing, device functions and print specifications. Preview of double-sided faces is concurrently provided when double-sided printing is specified. Display is performed by generation of data which allows print preview that reflects consideration of device information and document data. Data is generated for perspective-reverse-face preview when page-specification information is set for double-sided faces.
Claims22
An information-processing apparatus for displaying a preview image based on document data generated by an application, comprising:
- a setting unit constructed to set double-sided printing;
- a designation unit constructed to designate a display of the preview image;
- a data-generating unit constructed to generate an obverse face preview image based on a page to be placed on the obverse face of a sheet included in the document data and a perspective-reverse-face preview image based on a page to be placed on the reverse face of the sheet included in the document data when the double-sided printing is set by setting unit and said designation unit designates the display of the preview image;
- and
- a display controlling unit constructed to display a merged preview image based on the obverse face preview image and the perspective-reverse-face preview image;
- wherein said display controlling unit displays the merged preview image so that the perspective-reverse-face preview image is recognizable as the image of the reverse face of the sheet.
An information-processing method of displaying a preview image based on document data generated by an application, comprising:
- a setting step of setting double-sided printing;
- a designating step of designating a display of the preview image;
- a data-generating step of generating an obverse face preview image based on a page to be placed on the obverse face of a sheet included in the document data and a perspective-reverse-face preview image based on a page to be placed on the reverse face of the sheet included in the document data when the double-sided printing is set by setting step and said designation step designates to display the preview image;
- and
- a display controlling step of displaying a merged preview image based on the obverse face preview image and the perspective-reverse-face preview image;
- wherein said displaying controlling step displays the merged preview image so that the perspective-reverse-face preview image is recognizable as the image of the reverse face of the sheet.
A computer-readable storage medium containing a computer-executable program for displaying a preview image based on document data generated by an application, comprising:
- setting program code for setting double-sided printing;
- designation program code for designating a display of the preview image;
- data-generating program code for generating an obverse face preview image based on a page to be placed on the obverse face of a sheet included in the document data and a perspective-reverse-face preview image based on a page to be placed on the reverse face of the sheet included in the document data when the double-sided printing is set by said setting program code and said designation program designates to display the preview image;
- and
- display controlling program code for displaying a merged preview image based on the obverse face preview image and the perspective-reverse-face preview image;
- wherein said display controlling program code displays the merged preview image that the perspective-reverse-face preview image is recognizable as the image of the reverse face of the sheet.
