A method, non-transitory computer readable medium and apparatus for generating an output image are disclosed. For example, the method includes receiving an image, applying a first filter, applying a second filter, calculating a difference between the image with the second filter that was applied and the image with the first filter that was applied and transmitting the difference to a sharpening module and a segmentation module to generate the output image.

A system prints a document by generating a device-dependent font that is appropriate for the document and the print device. The system does this by identifying a font for the document, identifying an affine transformation matrix for the font, using the device resolution and current page location of the print device to modify the affine transformation matrix to yield a current transformation matrix, adding a reverse of the current transformation matrix to the affine transformation matrix to yield a modified font matrix, and generate a print file using the modified font matrix. The print device then uses the print file print the document with a font corresponding to the modified font matrix.

Provided is an information processing apparatus including: a PDL analysis unit that acquires an output resolution of input PDL data when a tile drawing instruction is included in the PDL data, and calculates a drawing size of a tile drawing based on the tile drawing instruction and the output resolution; an average color calculation unit that calculates an average color of the tile drawing based on the tile drawing instruction when the calculated drawing size is smaller than a predetermined value; and a rendering unit that renders the tile drawing instruction based on the calculated average color. The average color calculation unit calculates the average color based on a transparency level of a unit tile included in the tile drawing instruction.

A positional-deviation correcting device includes a reading device and control circuitry. The reading device reads recording media on which marks and each of adjustment charts having different image densities are formed in accordance with the image densities. The control circuitry acquires data on image formation positions of the marks on the recording media, based on a reading result of the marks; and corrects an image formation position of an image to be formed on a recording medium. The control circuitry calculates a correction value of the image formation position corresponding to an image density for each of the image densities corresponding to the adjustment charts on a one-on-one relationship, based on a reading result of the adjustment charts; interpolates correction values corresponding to the image densities on a one-on-one relationship; and calculates a correction value of the image formation position corresponding to another image density different from the image densities.
