A frame memory area for editing a bit pattern as data to be displayed on a display device according to predetermined parameters, and one or more bit patterns of the same window unit as data to be output to a printer device according to predetermined parameters. a parameter setting means for independently setting parameters for editing as data to be displayed on the display device and parameters for editing as data to be output to the printer device; Prepared.

[Industrial application field]

The present invention relates to a device that edits a bit pattern developed on a memory having a bit map structure when displaying so-called multimedia, and in particular, it is also assumed that the bit pattern is outputted by a printer device. The present invention relates to a bit pattern editing processing device in a bitmap memory.

[Conventional technology]

For example, when displaying characters, figures, etc. on a display device in word processors, personal computers, etc., display information for one screen is generally stored in memory. So-called bitmap memory, which stores information in the form of bit information, has come into use. In addition, display media are not limited to text and graphics, but are also expanded to include image information extracted from photographs, etc. Furthermore, these display media, text, graphics, and image information are edited and combined with each display media, A multimedia display system has also been realized in which the combined information is displayed on a display device. Specifically, to synthesize each display media in this multimedia display method, bit patterns related to characters, bit patterns related to figures, and bit patterns related to image information developed on a bitmap memory are respectively transferred onto the bitmap memory. Enlarging, scaling according to predetermined parameters (enlargement/reduction magnification, character font, vector conversion parameters, etc.)
Editing processes such as reduction, extraction of important parts, deletion, format change, and combination of hats are performed. Then, the new bit pattern, which has been edited in this way and has been synthesized and developed on the bitmap memory, is displayed on the display device.

On the other hand, in recent years, there has been a demand for the information displayed on the display device as described above to be output as is to a printer device (hard copy, etc.).

Conventionally, in response to this demand, a bit pattern developed on a bitmap memory as data to be displayed on a display device is supplied as is to a printer device, and an output corresponding to the bit pattern is obtained.

[Problem that the invention seeks to solve]

By the way, in the bit pattern editing processing device as described above, if the resolutions of the display device and printer device used are different, the quality of the output from the printer device will be lower than that displayed on the display device.

This is because the bit pattern, which was originally edited as data to be displayed on a display device and developed on a bitmap memory, is supplied as is to a printer device having a different resolution.

Further, in recent years, the resolution of printer devices has become higher than that of general display devices, and there is a strong desire to use such printer devices to clearly obtain hard copies of information displayed on display devices.

Therefore, an object of the present invention is to separate data to be displayed on one display device and data to be output from a printer device and edit them on a bitmap memory.

Parameter 1 to be set independently -
It is equipped with 11 stages 5.

[Effect]

A bit pattern of information (characters, figures, images, etc.) required for the window memory area 2 in the memory 1 is developed for each window. The data to be displayed on the display device 6 is determined by the display H set by the parameter setting means 5.
According to the parameters (enlargement, reduction rate single character font, vector conversion parameters, etc.), one or more bit patterns in units of window W written in J: are edited and developed in the frame memory area 3. In addition, the printer device 7
The data to be outputted is processed by editing one or more bit patterns at the first position in the write window W according to the printing parameters set by the parameter setting means 5.
The image is developed in the image memory area 4.

Here, the bit pattern developed in the frame memory area 3 is supplied to the display device 6, and the bit pattern developed in the image memory area 4 is supplied to the printer device 7. Regarding the bit pattern of each memory area 3, 4F, the original window W
If the bit patterns of the units are the same, a hard copy of the information displayed on the display device 6 is output from the printer device 7. The parameters related to the display bit pattern editing process and the parameters related to the print output bit pattern editing process are independently determined by the parameter setting means 5 to be optimal based on the resolution of the display device, printer device, etc. ing.
