Display and control of permitted data processing based on control information extracted from the data

For generating characters form data stored in a vector format, are provided two kinds of based skeleton data and data which depends on type style; from this a plurality of type styles are generated. The base skeleton data has a start portion, a middle portion, and an end portion. (Or, the base skeleton data has skeleton priority data, skeleton connection data, face modification data, or stroke weight data.) When the type style is generated, bit map, byte map, outline coordinate type, or skeleton coordinate type is generated as desired, in accordance with an output request.

Character generation using data of plural types to which differing priorities are assigned

An image processing apparatus for drawing the inside of an image area which is expressed by vector data has reversal and painting means for sequentially reversing write dots (data) along the storage direction in correspondence to one outline which is specified by vector data, for writing the reversed write dots into an image memory, and for painting the inside of an image area like a closed figure in the image memory. Thus, the area in a closed figure can be painted at a high speed using an apparatus which has a simple construction. The optimum reversal and painting method can be selectively switched in accordance with the attribute data of an image area to be painted, so that the optimum. painting process can be executed at a high precision and at a high speed.

Image processing apparatus with paint-in of outline interiors

An image processing system has bit map figure data of a plurality of sizes and edits a document on the basis of this data. This system comprises an input device to input a figure by a polygon definition, an instructing circuit to instruct the input figure with a desired size, and an output device to output the figure with the desired size in response to the input instruction. The figure data of standard sizes are stored as bit map data into a memory even when auxiliary characters are registered. When inputting figure data of a size larger than the standard sizes, it is stored as polygon definition data. Thus, the memory capacity can be reduced and the labors and time to define an auxiliary character can be reduced.

Image processing system having outline font data input

A character processing apparatus for recognizing coordinate information expressing a character, an exterior outline, an interior outline, a horizontal line and a vertical line; classifying the coordinate information expressing a character, the exterior outline, the interior outline, the horizontal line and the vertical line, and then determining a pair of the horizontal line and the vertical line; and setting a skipping order at the time of low pixel so as to be converted into character data for a bit map development composed of a control point coordinate for expressing the outline of the subject character, band information and coordinate value information about the control point which is not included in the band information.

Character pattern generation

There is disclosed an image processing apparatus capable of forming white patterns on black background, hatched patterns, patterns with shadows, etc., in a simple manner. The apparatus has plural memories, which are used for defining mutually corresponding dots. These dots are subjected to logic processing, and the obtained dot patterns are released in combination.

Image processing system

A character pattern generating method and apparatus which enables storage of a large amount of font data with a small memory capacity and increase pattern-bitmapping speed. The apparatus stores element information representing common elements for constructing patterns and construction information indicating the construction of each pattern in a font data memory such as a ROM. The sets of element information corresponding to a specified pattern are developed into bitmap data in an element bitmap area. The bitmapped data are synthesized in accordance with construction information for the pattern to be generated.

Simplified vector-format pattern generation

A character processing apparatus comprises: parameter memory means for storing type parameters; display means for displaying a list of a plurality of type vector fonts on the basis of the type parameters; selecting means for selecting a plurality of type vector fonts displayed by the display means; and converting means for converting each of the vector fonts existing in a designated interval in a vector font train which are input from input means and displayed by the display means into the type vector fonts selected by the selecting means, wherein the modified vector fonts which are frequently used and correspond to fundamental vector fonts are previously registered, and when modified vector font patterns are formed, the registered modified vector font patterns are displayed and selected, thereby enabling the parameters for the modified vector font patterns to be easily set.

A document processing apparatus and method inputs character code information corresponding to a character to be output, stores a character or symbol pattern in the form of a plurality of fonts, discriminates whether a character or a symbol pattern to be output exists across a plurality of lines, generates one character or a symbol pattern existing across a single line from one stored font based on one character code of the input character code information in the event that the character or symbol pattern to be output is discriminated to exist, across only a single line, and generates one character or symbol pattern existing across a plurality of lines from the plurality of stored fonts based on one character code of the input character code information in the event that the character or symbol pattern to be output is discriminated to exist across a plurality of lines.

Document processing apparatus and method for generating a character or

A character processing apparatus which has character data as a coordinate point array on contour lines and converts the character data into dot information and outputs. This apparatus includes: a discriminating circuit to discriminate whether two continuous points in the coordinate point array constitute horizontal or vertical line elements on the basis of the coordinate values between the two points; and an arithmetic operating device which, when it is determined that those two points constitute a horizontal or vertical line, enlarges or reduces a thickness of this horizontal or vertical line so that the relation of thickness of the horizontal and vertical lines is equal to the relation of thickness in the character data. The discriminating circuit performs the discrimination before the character data is converted into the dot information. The arithmetic operations are independently performed in accordance with a designated size with respect to the coordinate points indicative of a main outer shape of a character and to the coordinate points representative of an additional outer shape.
