An image forming apparatus includes: a first holding unit that holds a pixel value data sequence in which each of the data sequences is formed by a pixel value and a range of the pixel value or by the pixel value, the range of the pixel value, reference to a pixel, and a range of the reference; a second holding unit that holds a transparency data sequence in which each of the one-dimensional data sequences is formed by a coefficient representing transparency of a pixel in the image element and a range of the coefficient or by the coefficient, the range of the coefficient, reference to coefficient, and a range of the reference; and an image generation unit that forms an image from the pixel value data sequence, and that generates information about transparency of the image from the transparency data sequence.

Image processing apparatus and computer readable medium

An image processing apparatus includes: an accepting unit that accepts image information about each of a plurality of image elements to be synthesized; a comparing unit that compares a threshold value with a mixing ratio used in an operation to synthesize the image information according to a given mixing ratio; and a setting unit that sets an attribute of an image element in an area where the plurality of image elements are overlapped with each other synthesized according to a comparison result obtained by the comparing unit.

Image processing apparatus, image forming apparatus, image processing method, computer data signal, and recording medium

An image processing apparatus for generating scaled image data includes a receiver that receives an input of pixel value information of each pixel which is contained in image data to be processed in raster scan order, a first memory that stores the pixel value information input in the raster scan order, a destination address generator that generates destination address information in the second memory to specify a destination location of the pixel value information stored in the first memory in response to the specified scaling factor, and a transferring unit that transfers the pixel value information from the first memory to the second memory based on the generated destination address information.
