Abstract
An image forming apparatus according to the present disclosure includes an image data analysis unit and an image conversion unit. The image data analysis unit is configured to identify a width-directional resolution and a height-directional resolution of image data. If the width-directional resolution and the height-directional resolution are not the same, the image conversion unit is configured to change at least one of pixel counts in a width direction and a height direction to cause a first aspect ratio for printing to match a second aspect ratio of the image data.
Claims14
An image forming apparatus, comprising:
- an image data analysis unit configured to identify a width-directional resolution and a height-directional resolution of image data;
- and
- an image conversion unit configured to change, if the width-directional resolution and the height-directional resolution are not the same, at least one of the width-directional resolution and the height-directional resolution to cause a first aspect ratio for printing to match a second aspect ratio of the image data, wherein the image conversion unit is further configured to:
- calculate a magnification of an image size based on a pixel count of a maximum print area of a print sheet and a pixel count of aspect-ratio-matched image data;
- use the magnification to change both a width and a height of the aspect-ratio-matched image data;
- and
- set the magnification to a smaller one of:
- a first magnification ratio obtained by dividing a width-directional pixel count of the maximum print area of the print sheet by a width-directional pixel count of the aspect-ratio-matched image data;
- and
- a second magnification ratio obtained by dividing a height-directional pixel count of the maximum print area of the print sheet by a height-directional pixel count of the aspect-ratio-matched image data.

A non-transitory computer-readable storage medium that stores an image forming program to be executed by a computer of an image forming apparatus, the image forming program comprising:
- a first program code that causes the computer to identify a width-directional resolution and a height-directional resolution of image data;
- and
- a second program code that causes the computer to change, if the width-directional resolution and the height-directional resolution are not the same, at least one of the width-directional resolution and the height-directional resolution to cause a first aspect ratio for printing to match a second aspect ratio of the image data, wherein the second program code further causes the computer to:
- calculate a magnification of an image size based on a pixel count of a maximum print area of a print sheet and a pixel count of aspect-ratio-matched image data;
- use the magnification to change both a width and a height of the aspect-ratio-matched image data that is obtained after the pixel count is changed;
- and
- set the magnification to a smaller one of:
- a first magnification ratio obtained by dividing a width-directional pixel count of the maximum print area of the print sheet by a width-directional pixel count of the aspect-ratio-matched image data;
- and
- a second magnification ratio obtained by dividing a height-directional pixel count of the maximum print area of the print sheet by a height-directional pixel count of the aspect-ratio-matched image data.
