Abstract: An example electronic apparatus includes a processor and a memory to store instructions executable by the processor. The processor, by executing the instructions, is to obtain, for a document including handwritten text, a text layer including text and an image layer including a handwritten image corresponding to the text, detect text related to an edit request of a user, retrieve, in the text layer, at least one character constituting the detected text, retrieve, in the image layer, at least one character image mapped to the retrieved at least one character, and apply a first handwritten image including the retrieved at least one character image to the image layer.

Abstract: An image forming apparatus includes a plurality of photosensitive drums respectively corresponding to a plurality of colors to print, on a recording medium, color chart of a plurality of vertical lines in a sub-scanning direction to a main scanning direction of the recording medium and to be arranged at intervals along the main scanning direction. A vertical line of the plurality of vertical lines includes at least two colored sub-lines to be formed by corresponding at least two photosensitive drums. A processor is to perform a correction in non-linear color registrations in the main scanning direction using an image of the color chart.

Abstract: An example of an apparatus including a front-end engine to receive document data in a first format for printing via a network. The apparatus includes a conversion engine in communication with the front-end engine. The conversion engine is to carry out a conversion of the document data from the first format to an uncompressed format, wherein the conversion engine generates metrics associated with the conversion. The conversion engine parses the document data in the uncompressed format into a plurality of separations. The apparatus includes a compression engine to process a separation of the plurality of separations from the uncompressed format to a second format, wherein the second format is a predetermined format associated with a printing device. The apparatus includes a print engine controller to transmit the separations in the second format to the printing device, wherein the print engine controller uses the metrics to predict a starvation condition.

Abstract: Examples disclosed herein relate to a rigid board with a pliable region. An example system can include a board including a cut to form a beam region of pliability in the board. An example system may include a component to be mounted on the beam region. In an example, the cut can increase flexibility of the beam region relative to the board allowing movement of the component to a target alignment for the component.
