A monitoring device is provided on a LAN to which a communication device that is a target of a denial-of-service attack is connected, and monitors a packet transmitted to the communication device via an ISP network. A restricting device is provided on the ISP network, and restricts a packet to the LAN. The monitoring device detects an attack by the packet on the communication device, and transmits protection request information indicating a request for protection against the attack to the restricting device. The restricting device restricts a packet transmitted to the communication device via the ISP network based on the protection request information.

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.

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.

Character processing apparatus for selectively modifying a font pattern

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.

An image processing apparatus for correcting shape errors when a graphic image to which contour line data was given is painted and developed comprises: an input device to input contour line data of image information; a circuit to make a contour line pattern of the image information on the basis of the contour line data; a circuit to make a painted pattern in which the inside of the contour line pattern was painted; a circuit to narrow the painted pattern; and a contour line correcting circuit to obtain the exclusive-OR combination of the narrowed painted pattern and the contour line pattern. The contour line pattern is eliminated from the painted pattern by the narrowing circuit. The contour line correcting circuit has a converter to convert the contour line pattern in correspondence to the drawing direction of the contour line pattern and obtains the exclusive-OR combination of the converted contour line pattern and the painted pattern. This apparatus can prevent a small blank region in an image being painted over and can effect a feature of a contour line.

A document processing system for formatting document information in accordance with a format includes a disk apparatus which independently has a document file, an address table file, and a format information file. The document file stores the document information corresponding to predetermined regions. The address table file stores an address table corresponding to the document information. The format information file stores the format information corresponding to the document information. A control circuit, in response to a page designation, controls the three files to correct format information and address information for document information preceding the designated page.

A word processor capable of creating a formula during a document editing process by automatically setting a range of a formula in a document being edited with an instrument of a formula process start command and allowing a switching operation between the document editing process and the formula creating process to be easily made. This allows the formula to be edited on a block basis, thereby facilitating the editing operation such as modification, addition, or deletion of the formula in accordance with any editing of character trains or symbols inside and outside the formula in a well-balanced manner. The word processor is also capable of automatically defining the position, size, and form of a symbol in accordance with the length and form of an object to which the symbol is to be added, so that the position, size, and form of the symbol can be automatically accommodated in accordance with any change in the object to which the symbol is to be added without bothering an operator. The word processor is further capable of not only adding a symbol to an already input text, but also inputting paired symbols which are mutually spaced apart such as a pair of parentheses with a single input operation.
