Abstract: A processor of an information processing apparatus determines, if a drawing object making up page data of a print job is a transparent object having an alpha channel as color information, whether the transparent object overlaps another drawing object. If the transparent object does not overlap the other drawing object, the processor converts drawing data of the transparent object into drawing data of a drawing object not having an alpha channel as color information. If the transparent object overlaps the other drawing object, the processor does not convert the drawing data of the transparent object into the drawing data of the drawing object not having the alpha channel as color information. Based on the converted drawing data and on the non-converted drawing data, the processor creates PDL data to be output to an image forming apparatus.

Abstract: According to the present invention, in a case where a plurality of corresponding pixels in a pre-converted original image is determined to include both a fully transparent pixel and a not fully transparent pixel, a color value of a pixel in a converted image is obtained based on the color value of the not fully transparent pixel among the corresponding pixels, and a degree of opacity of the pixel in the converted image is obtained by using the degrees of opacity of all the corresponding pixels.

Abstract: Density adjustment performed by a user to obtain a desired tint by a density adjustment function has been difficult because of the difficulty in determining which density region of which color needs to be adjusted. An image processing apparatus displays a print preview image corresponding to an image to be printed, causes a user to select a position on the displayed print preview image, and acquires color information of the selected position. The image processing apparatus further determines, from among a plurality of density regions, at least any one of cyan, magenta, yellow, and black density regions corresponding to the acquired color information, and displays an adjustment screen for adjusting a density in the determined density regions.

Abstract: An output density range is divided such that, after gradation targets have been applied, adjusted density ranges for output are uniform across all objects. Furthermore, through reverse calculation using the gradation targets that are set in one-to-one correspondence with the objects, adjusted density ranges of the respective objects are set independently.

Abstract: According to the present invention, there is provided a color image forming apparatus which includes image forming units forming images, each for each color component, and superimposes the images of the color components on one another to form a color image. The image forming apparatus includes a scan line changing unit shifting the position of each pixel in a sub scanning direction for each color component of halftone image data to be processed so as to cancel a shift amount of a scan line on an image carrier in each of the image forming units in the sub scanning direction; an interpolation inhibited area determining unit determining an interpolation inhibited area in the image data; and an interpolation unit applying an interpolation process for smoothing a pixel-level shift caused by shifting of image data by the scan line changing unit to the image data excluding the interpolation inhibited area.

Abstract: According to this invention, the image attribute is determined by determining whether the image of each color component of color image data having undergone a screen process is a continuous tone image, and whether the image of each color component is a pattern image. Whether to perform an interpolation process is determined for each color component based on the attribute determination result of each color component. If it is determined that the images of all the color components are pattern images, interpolation determination results do not coincide with each other, and there is a color component determined to represent a continuous tone image, the interpolation determination result of this color component is overwritten with the interpolation determination result of the remaining color components. The interpolation process is executed in accordance with the interpolation determination result.
