Abstract

PURPOSE:To decrease file edit processing time by providing a flay with a non- real-data sign in a relative address area when data in a data area is not a real data. CONSTITUTION:When a font is to be added or an existing font is to be modified and if a desired code is not in a relative address area H2, the relative address area H2 of a header is rebuilt to proceed to other processing. If a desired code is in H2 and a raster size is equal to or smaller than a size to be stored now, the raster size of a leading word is replaced by the present one to overwrite the raster. If the raster size is larger than that to be stored now, a file size is expanded by an area required by the present raster and the present raster is written in an area following a data area D1 and a specified relative address in a field corresponding to the area H2. When an existing font is to be deleted, the address of the raster's leading address is made negative to imply the absence of a real data despite the presence of an area.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a file editing device used in a rask-type digital printing device and the like.

[Conventional technology]

FIG. 4 shows a schematic diagram of a Rask one-type digital printing system, in which 1 is a display, 2 is a keyboard, 3 is a memory device, 4 is a processing device, 5 is a fixed disk device, 6 is a printing device, and 6 is a printing device. 4 converts data input from the keyboard 2 into font information in the memory device 3 and outputs it from the printing device 6.

Conventionally, the font file in the memory device 3 is
As shown in the figure, data (1), (2), and (3) consisting of bitmap areas consisting of rasters, code data for each font, and a part of the header that specifies the relative address to each raster are included. It is formed. When editing a file, for example, changing or deleting the size of the Rask in data (2), if the previous data is left, the processing time will increase and the storage capacity of the memory device 3 may be exceeded.

For this reason, unnecessary data is organized in the processing device 4 and transferred to the fixed disk device W5, and the organized data is loaded again into the memory device M3 to edit the file.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional font file editing, if editing is frequently repeated, it is necessary to perform amp editing with the fixed disk device 5 each time, which increases the processing time. have.

The present invention solves the above problem, and aims to provide a file editing device that can shorten the processing time in file editing.

[Means for solving problems]

To this end, in a file including a data area and a relative address area indicating a relative address of the data area, when the data in the data area is not real data, the file editing device of the present invention The feature is that there is a flag indicating that there is an area, but it is not actual data.

[Effect]

In the present invention, for example, as shown in FIG. 1, if O is entered in the relative address area H2, that area is determined not to exist, and other areas are evaluated as addresses, and the first word of the actual data is -1. If so, it is interpreted that the area exists but is not actual data. This can also be realized by making the address to the data area DI a negative value in the relative address area H2. When the data is finally written out for storage or released, this area without actual data is deleted in a separate process, resulting in an efficient editing device.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing one embodiment of a file structure applied to the file editing device of the present invention, and FIGS. 2 and 3 are diagrams for explaining the processing flow of the file editing device of the present invention. .

In Figure 1, Hl and H2 are part of the header of the file, and 1 is the folder/header for identifying the file type.
2 is a holding code area that stores the first and last fonts when the fonts existing in this file are represented by code data, and 3 is a file length (length l of HX and length l of Dl! area). H2 is a relative address area, and is an array from the first code to the last code shown in the retained code area 2, and stores the relative distance to each raster in the data area D1, and D+ is a data area, consisting only of rasters. It is a bitmap area, and the first word thereof contains size information of the rasku.

In the present invention, a code that does not have actual data in the data area I)+ does not have 1 in the relative address area Hz" is prepared, and in an editing state where writing is performed frequently, the This allows for smoother editing by providing a flag that says ``There is, but it is not data.'' For example, if you enter O in the relative address area H2, that area will not exist. If the first word of the actual data is -1, it is interpreted that there is an area but not the actual data.This means that in the relative address area Hz, This can also be achieved by setting the address to the data area D1 as a negative value.Then, when finally releasing the data written for storage, this area without actual data must be deleted in a separate process. This makes it an efficient editing device.

Next, the flow of processing in file editing will be explained.

Figure 2 shows the flow when adding a new font or modifying an existing font. First, determine whether the desired code is in the relative address area H2.
, if not, recreate the relative address area H2 of the header and proceed to other processing (■). If the desired code is in Ht, determine whether the raster size is larger than the size to be stored this time (■) , if they are equal or smaller, replace the rask size of the first word with the current size and overwrite the raster. On the other hand, if the size of the raster is larger than the size to be stored this time, expand the file size by the amount of the current raster, write the current raster after the data area (area 4 in Figure 1), and store it in the area. 4 in the relative address area H2.
write to the corresponding field. Therefore, the data corresponding to the address before being written will not be used.

When deleting an existing font, the address of the first area of the rasque obtained from the corresponding field of the relative address area H2 is made negative. As a result, the address itself has no meaning, and it is interpreted as if there is an area but not actual data.

FIG. 3 shows the flow when creating a save file using the save command. As mentioned above, when an existing font is deleted or when the raster size becomes large, there is unnecessary data in the data area D1, and when the raster size becomes small, there is unnecessary data in the data area D1. Since there is blank data, all codes in the relative address area H8 are rearranged, that is, after copying Hl and H3 (■, ■), each code in the relative address area H8 is rearranged at the beginning of the lasque. It is necessary to judge whether the area is negative (■), and if it is negative, proceed to step ■; if it is negative, the address of Heragu may be set to 0 (■), proceed to step ■. In step (2), it is determined whether the above processing has been performed for all codes, and when all codes have been processed, the file length of H1 is changed (2).

〔Effect of the invention〕

As described above, according to the present invention, a code that does not have actual data in the data area D+ is stored in the relative address area H1 as "
In editing situations where frequent writing is required, by providing a flag that says 'area exists but not data', it enables smoother editing and improves file editing. Processing time can be shortened.
