This is repeated until there is no more image data (10), and when the data is completed, the element of the reference counting unit 272 corresponding to the block indicated by the image pointer P is reduced by "1" (11).

FIG. 13 is a flow chart showing a detailed procedure of the image image drawing processing routine shown in FIG. Note that (1) to (11) indicate each step.

First, it is determined whether or not the image data referred to by the page data is in the reception buffer 271 (1). If it is determined that the image data is in the reception buffer 271, the page pointer is stored in the image pointer P. (2). And
The data pointed by the image pointer P is read (3), and is expanded into a bit map in the expansion memory 24 by the image expansion unit 25 (4). It is determined whether or not the image pointer P is pointing to the last data of the block (5). If it is not the last data, the image pointer P is advanced to the next data (6). A block indicated by the data connection unit 273 corresponding to the block indicated by is obtained, and the image pointer P is pointed to the head data of the block of the reception buffer 271 (7). This is repeated until there is no more image data (8).

On the other hand, if it is determined in step (1) that the image data is not in the receiving buffer 271, the image data is read out (9), and the image expanding unit 25 expands the image data into a bit map in the expansion memory 24 (10). ) Is repeated until there is no more image data (11).

FIG. 14 is a flowchart showing a detailed procedure of the page data release processing routine shown in FIG. Note that (1) to (10) indicate each step.

First, it is determined whether or not the image data referred to by the page data is in the reception buffer 271 (1). Otherwise, since the image data is in the page buffer 28, the area is changed. Release (2). In the case of the reception buffer 271, the image pointer P is pointed to the head data of the image (3). Then, it is determined whether the data pointed by the image pointer P is the end of the block (4). If the data is not the last data, the image pointer P is advanced to the next data (5). The element of the reference counting unit 272 corresponding to the block pointed by is reduced by “1” (6), and the data linking unit 2 corresponding to the block pointed to by the image pointer P
The block indicated by 73 is acquired, and the image pointer P is pointed to the head data of the block of the reception buffer 271 (7). This is repeated until there is no more image data (8).
The element of the reference counting unit 272 corresponding to the block indicated by “1” is reduced by “1” (9), and the area of the page data is released (10).

According to the present embodiment, the reception buffer 271
When there is not much image data in the reception buffer 271, the reception buffer 271 is shared by the reception data and the image data so that the image data can be stored in the reception buffer 27.
The process of copying from 1 to the page buffer 28 can be reduced, and the copying time can be saved.

Further, by reducing the number of copies of the image data from the reception buffer 271 to the page buffer 28, the memory capacity of the page buffer 28 can be saved.

On the other hand, when the amount of image data in the reception buffer 271 increases, the shortage of the reception buffer 271 can be prevented by copying the image data from the reception buffer 271 to the page buffer 28.

Further, since the receiving buffer 271 is constituted by a memory having a series of addresses, it is very similar to the structure of the receiving buffer generally used in the past.
Therefore, when the reception data is stored in the same block, the same reception processing as in the related art can be performed.

In the adjacent block, the movement of the pointer from the last data of the previous block to the head data of the subsequent block can be performed by exactly the same operation as the movement of the pointer in the adjacent data in the block. It can be.

Further, since the block of the reception buffer 271 is in units of a plurality of bytes, not all of the memory of one block is used and waste occurs. However, the area to be copied is set to the same number of bytes as the image data. By allocating memory in units smaller than the block of the receiving buffer, the memory required to hold the image data can be reduced.

[Third Embodiment] Hereinafter, FIGS.
A third embodiment will be described with reference to FIG.

If it is determined that the input image is not an image image drawing command, page data is created in the same manner as in the related art (11). On the other hand, if it is determined that the instruction is an image image drawing command, a page data creation processing routine of the image image is executed (10). This is repeated until the data of one page is completed (12). The image data page data creation processing is the same as in the first embodiment.

Then, for each area of the page, the page data in the page buffer 28 is sequentially analyzed by the image developing unit 25 (13), and it is determined whether or not the command is an image drawing command (14). If so, it is developed in the development memory 24 (15). If it is determined that the command is an image image drawing command, an image image drawing process routine is executed (16), and steps (13) to (13) are performed until the page data ends. Repeat 17).

When the development of the page data in each area is completed, the image forming unit 26 prints the development memory 2 on the recording paper.

(2), an area for copying the image data and a data link corresponding to the area are secured in the page buffer 28 (3), and the head address of the secured area is stored in the page data of the image drawing command. Set (4). Then, the image data pointed by the image pointer P is copied to the area secured in the page buffer 28 (5), and it is determined whether the data pointed to by the image pointer P is the last of the image data (6). If it is determined, the process proceeds to step (10). If it is not the last, it is determined whether the data pointed to by the image pointer P is the last of the block (7). If it is not the last data of the block, it is determined. The image pointer P is advanced to the next data (8), the process returns to step (5), and steps (5) to (8) are repeated.

On the other hand, if it is determined in step (7) that the data is the last data of the block, the page buffer 28
The value of the data connection unit 273 of the reception buffer pointed to by the image pointer P is copied to the data connection unit corresponding to the image image data copied in (9), and the element of the reference counting unit 272 corresponding to the block pointed to by the image pointer P Is reduced by "1" (10), and the process ends.

FIG. 17 is a flowchart showing the detailed procedure of the image processing routine for drawing the image shown in FIG. Note that (1) to (7) indicate each step.

First, the head address of the image data of the page data is entered in the image pointer P (1).
Then, the data pointed to by the image pointer P is read out (2), and is expanded into a bit map in the expansion memory 24 by the image expansion unit 25 (3). Next, it is determined whether or not the image pointer P is pointing to the last data of the block (4). If it is determined that the data is not the last data, the image pointer P is advanced to the next data (5), and If it is determined that there is, the block pointed to by the data connection unit 273 corresponding to the block pointed to by the image pointer P is acquired, and the image pointer P is pointed to the head data of the block of the reception buffer 271 (6). . This is repeated until there is no more image data (7).

FIG. 18 is a flowchart showing a detailed procedure of the page data release processing routine shown in FIG. Note that (1) to (7) indicate each step.

First, the image pointer P is pointed to the head data of the image (1). Then, it is determined whether or not the image data referred to by the page data is in the reception buffer 271 (2). If not, the image image data is in the page buffer 28. The corresponding data linking unit is released (3), and in the case of the reception buffer 271, the element of the reference counting unit 272 corresponding to the block indicated by the image pointer P is reduced by "1" (4), and the block indicated by the image pointer P is deleted. Is obtained, and the image pointer P points to the first data of the block of the reception buffer 271 (5). This is repeated until there is no more image data (6). When the data is completed, the page data area is released (7), and the process is terminated.

According to the present embodiment, the reception buffer 271
When there is not much image data in the reception buffer 271, the reception buffer 271 is shared by the reception data and the image data so that the image data can be stored in the reception buffer 27.
The process of copying from 1 to the page buffer 28 can be reduced, and the copying time can be saved.

Further, by reducing the number of copies of the image data from the reception buffer 271 to the page buffer 28, the memory capacity of the page buffer 28 can be saved.

On the other hand, when the amount of the image data in the reception buffer 271 becomes large, the image buffer is copied from the reception buffer 271 to the page buffer 28 to prevent the shortage of the reception buffer.

Since the reception buffer 271 is constituted by a memory having a series of addresses, it has a structure very similar to the structure of the reception buffer generally used in the past.
Therefore, when the reception data is stored in the same block, the same reception processing as in the related art can be performed.

Further, in the adjacent block, the movement of the pointer from the last data of the previous block to the head data of the subsequent block can be performed in exactly the same manner as the movement of the pointer in the adjacent data in the block. It can be.

Further, since the block of the reception buffer 271 is a unit of a plurality of bytes, the first block and the last block of the reception buffer holding one image image data do not necessarily use all the memory of one block. If the area to be copied is set to the same number of bytes as the image data, or if the memory is secured in units smaller than the block of the receiving buffer, the memory required to hold the image data is reduced. I can do it.
