Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for adding and outputting rule data, and relates to a method for adding and outputting rule data in a device that manually inputs vector data such as an electrostatic block in a frame, converts it into raster data, and outputs the raster data. Regarding the method.

[Conventional technology]

In the conventional method of converting vector data to raster data in an electrostatic plotter, etc., as shown in FIG. The vector data storage means 3 temporarily stores the sorted vector data sorted by the vector data sorting means 2, and the vector/raster conversion means 4 temporarily stores the sorted vector data in the vector data storage means 3. The sorted vector data stored in is read out and converted into raster data, the raster data storage means 5 temporarily stores the raster data converted by the vector/raster conversion means 4, and the output means 8 The raster data stored in the storage means 5 is read out to the output Ill and output as output data 7.

[Problem that the invention seeks to solve]

In the conventional hefter data to raster data conversion method described above, vector data is simply converted to raster data and output as output data. If you try to output by adding general rule data (referred to as rule data) (for example, if you try to create an image by adding a square grid to the image using an electrostatic block), include the rule data in the vector data. As the amount of vector data becomes extremely large, it takes an enormous amount of time to process it in the vector data sorting means and vector/raster conversion means, and the storage capacity of the vector data storage means becomes large. The disadvantage is that it is necessary.

In view of the above-mentioned points, an object of the present invention is to add rule data to raster data obtained by converting vector data and output it, thereby reducing processing time in vector data sorting means and vector/raster conversion means. An object of the present invention is to provide a method for adding and outputting regular data that requires less storage capacity of vector data storage means.

[Means for solving problems]

The rule data addition output method of the present invention includes a vector/raster conversion means for converting vector data into raster data, and the raster data converted by the vector/raster conversion means is repeatedly ORed with the rule data and output data is obtained. and rule data addition/output means for outputting.

[Effect]

In the rule data addition output method of the present invention, the vector/raster conversion means converts vector data into raster data, and the rule data addition output means repeatedly ORs the raster data converted by the vector/raster conversion means with the rule data. and output it as output data.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a configuration diagram showing an embodiment of the present invention. The rule data addition output method of this embodiment includes a vector data sorting means 2 that sorts input data 1 consisting of vector data in the output order when outputting it as output data 7, and a sorted data sorted by the vector data sorting means 2. vector data storage means 3 for temporarily storing vector data of;
vector/raster conversion means 4 for reading sorted vector data temporarily stored in the vector data storage means 3 and converting it into raster data;
raster data storage means 5 for temporarily storing the raster data converted by , and the raster data temporarily stored in the raster data storage means 5 are read out in the order of output, and rule data is repeatedly added thereto and outputted as output data 7. and rule data addition/output means 6.

Note that raster data is generally organized in words, and each bit represents the raster data (0) of the corresponding coordinate point.
Or 1) is shown. Hereinafter, one word of raster data will be named RASTER.

Referring to FIG. 2, the processing in the rule data addition/output means 6 includes a rule data generation condition input step 11, a minimum cell data creation step 12, an output coordinate initial value setting step 13, and a raster data one word reading step 14. , raster data end determination step 15, bit counter and additional data storage word clear step 1

In addition, in Fig. 2, X and Y are output coordinates, xl and Y

Yl) is the minimum cell data which is the minimum unit of rule data,
CD ATA indicates an additional data storage word, and I indicates a bit counter within the word.

Next, the operation of the rule data addition output method of this embodiment configured as described above will be explained.

When input data 1 for one drawing consisting of vector data is input manually, the input data 1 is sorted by the vector data sorting means 2 in the output order, and the sorted hefter data is temporarily stored in the vector data storage means 3. be done.

The sorted vector data temporarily stored in the vector data storage means 3 is read by the vector/raster conversion means 4 and converted into raster data, and the converted raster data is temporarily stored in the raster data storage means 5. Stored.

The raster data temporarily stored in the raster data storage means 5 is read by the rule data addition/output means 6, and the rule data is repeatedly added thereto and outputted as output data 7.

Specifically, in the rule data addition/output means 6, the user first inputs the conditions of the rule data to be added to the image (step 11)'.Since the rule data can be expressed by repeating the minimum unit of rule data, The set of rule data is named minimum cell data, and this minimum cell data is generated and held as CELL(X,,y,) (step 12).

Specifically, CBLL (X,, Yl) is 0 or 1
This value means 0 or 1 when the rule data at the point of the minimum intra-cell relative coordinates (X+, Yl) of the rule data is converted into raster data.

Next, the output coordinates X and Y are each set to an initial value of 0 (step 13), and one word of RASTER is read (step 14).

When the RASTER is completed (step 15), the bit counter (2) and the additional data storage word CDATA are cleared to zero (step 16), and the focus counter (2) is incremented (step 17).

Next, it is determined whether the output coordinate Y is larger than the maximum value YMAX (step 18), and if it is, the output coordinate Y is cleared to zero and the output coordinate X is incremented (
Step 19).

Subsequently, the minimum intra-cell relative coordinates X1 and Y are calculated. For details, set the output coordinates X and Y to the maximum value of relative coordinates
The remainder after dividing by IMAX and YIMAI+ is set as relative coordinates X1 and Y (step 20).

Next, it is determined whether CELL (X,, Y,) is 1 or not (step 21), and if it is 1, the additional data storage word C
Let l be the focus indicated by the bit counter ■ of DATA (
Step 22).

Next, step 23 increments the output coordinate Y.
), it is determined whether the focus counter (2) is equal to the number of bits in one word (step 24).

- If not defeated, return to step 17 and repeat the process, - If defeated, take the logical sum of RASTER and the data of the additional data storage word CDATA and output it as output data 7 (step 25), then step Return to 14.

If it is determined in step 15 that RASTER has ended, the process ends.

On the plotter paper 9, a figure 1a based on the input data 1 and a grid 6a added by the rule data addition/output means 6 are drawn in a superimposed manner. In addition, in Figure 3,
The minimum cell of the rule data corresponds to the minimum rectangle surrounded by a solid line.

〔Effect of the invention〕

As explained above, the present invention provides a rule data addition output means to add rule data after converting vector data to raster data, thereby reducing the time required for sorting vector data and raster data of vector data. This has the effect that the time required for conversion to can be shortened and the storage capacity of the vector data storage means can be reduced.
