An information processing apparatus includes an acquisition unit that acquires a designated color which is designated as a color, which is converted into a specific color, of a pixel among pixels which express an image, a determination unit that determines whether or not a common color area, which is expressed by pixels in a common hue range, expresses prescribed information in the image, and a conversion unit that performs a first conversion process of converting a pixel corresponding to the acquired designated color into a specific color in the common color area which is determined to express the information, and performs a second conversion process of converting a pixel corresponding to a color in a wider hue range than the designated color into a specific color in the common color area which is determined to not express the information.

An image forming apparatus includes a memory, and a processor configured to: read a first image of a sheet in a state in which the sheet is held on a sheet holding unit, the sheet being a sheet on which an image has been formed; detect a symbol from the first image of the sheet which has been read, the symbol indicating an orientation of the first image; and, when the orientation of the first image indicated by the detected symbol is different from an orientation of a second image that is to be formed on the sheet, perform a correction process of matching the orientation of the first image with the orientation of the second image that is to be formed on the sheet, the orientation of the first image being indicated by the detected symbol.

Image forming apparatus and non-transitory computer readable medium

An image forming apparatus includes a memory and a processor configured to output an image formed based on image data including predetermined specific text after replacing a color of one or more portions in the image data with a special color that is in advance associated with the specific text, the one or more portions being assigned a color identical or similar to a color of the specific text to form the image.

An information processing apparatus includes a detector, a receiver, and an image processor. The detector is configured to detect a punch hole candidate partial image having a punch hole accuracy indicating whether the punch hole candidate partial image is a punch hole image is less than a first threshold value and equal to or greater than a second threshold value smaller than the first threshold value, from plural partial images constituting a read image of a document. The receiver is configured to display the punch hole candidate partial image, and receive an instruction from a user as to whether to perform image processing on the punch hole candidate partial image. The image processor is configured to perform the image processing on the punch hole candidate partial image when the receiver receives an instruction to perform the image processing on the punch hole candidate partial image.
