JP2003006009A - Method for converting hpgl file into file in svg form - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a program capable of analyzing an HPGL (plotter file standard of Hewlett Packard Company) file and converting the data as SVG (scalable Vector Graphics) data as a language on the XML base. SOLUTION: This method is characterized by having a step (1) to read the HPGL file, a step (2) to translate an HPGL into an intermediate language and a step (3) to convert the HPGL file into SVG.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention analyzes an HPGL file, which is a standard format of an industrial system, and analyzes it into an intermediate language to convert it into an SVG file.
Regarding programs that can be converted and saved in the format.

[0002]

2. Description of the Related Art Conventionally, there are various versions of HPGL, it is difficult to exchange data between applications, and since the format of HPGL is a list of numbers and character strings, it takes time to analyze when a problem occurs. . Also, HP
The GL could not be printed without a plotter, and it was impossible to send it by fax because the size of the drawing handled by the industrial system was large (A0, A1).

[0003]

According to the conventional method, the HP
In order to replace and check the GL, there is no choice but to purchase the software or send it to the plotter, and if the plotter equipment is old or the software version is old, it cannot be issued. In addition, the drawings were so large that they could not be sent by fax. Furthermore, it was impossible to manage sharing on the Internet.

The present invention is to solve the above-mentioned problems. If there is an HPGL file, it can be converted into SVG and shared management on the Internet, and CAD.
It can be displayed on the screen without software and can be sent as a fax instead of via the Internet.

[0005]

As a means for solving the above-mentioned problems, the present invention reads an HPGL file, analyzes the read data, translates it into an intermediate language, and executes SVG.
It consists of a program to convert to.

The present invention is mainly used in industrial and mechanical systems.
You can publish GL files without new equipment. In addition, A0 and A1 size blueprints could not be sent by fax until now, but they can be converted to SVG format and sent by email instead of fax. Furthermore, sharing management is possible on the Internet.

[0007]

Embodiments of the present invention will be described below with reference to the flowcharts.

1 and 2 are flow charts showing an embodiment according to the present invention.

The operation of the present invention will be described with reference to the flowchart of FIG.
Read the file, and if the reading is successful, at 2, HPG
The L file is analyzed and translated into an intermediate language, and SVG conversion processing is performed in 3.

In the flowchart of FIG. 2, the intermediate language translation process is started at 4, the read HPGL data is taken out, and after the automatic correction process, it is arranged in the intermediate language region. SV at 5
The G conversion process is started, the intermediate data is extracted, and the process is rewritten in the SVG language. After conversion in SVG format, sharing management becomes possible on the Internet.

The first effect is that if the HPGL file is present, no new equipment such as a plotter is required.

The second effect is that since the HPGL file can be sent by mail, it can be used as a substitute for FAX.

The third effect is that it is not dependent on CAD software.

A fourth effect is that since it can be converted in the SVG format, it can be shared and managed on the Internet.
