DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for controlling display data in an output device, and more particularly to a method and apparatus for displaying screen data without depending on the resolution of a device to be output, and a recording medium.

[0002]

2. Description of the Related Art In a conventional information processing apparatus, when outputting data to an output device such as a display device or a printing device (printer), a screen is displayed with absolute coordinate values depending on the resolution of the device.

[0003]

The prior art having such a configuration has the following problems.

[0004] That is, the first problem is that the display screen is displayed with the absolute coordinate values depending on the resolution. Therefore, the screen occupied in the screen (display screen) of the display device due to the difference in resolution of the display device. Data) are different.

A second problem is that even if the display screen is displayed at a fixed size on the screen of the display device, there is a difference in the contents of the parts that can be displayed on the screen. This is because, if only the screen is enlarged / reduced, the number of components that can be accommodated in the screen is different or the image of the entire component is different unless the component arrangement in the screen is enlarged / reduced by the same processing. It is.

[0006] For example, Japanese Patent Application Laid-Open No. 4-291675 discloses at least at least attributes of a screen including resolution (X / DX, Y / DY), font size (FX, FY), and aspect ratio (AX, AY). A host computer that centrally manages each still image data created by a plurality of different terminals together with attributes, each of the terminals has a still image data storage unit that receives and stores desired still image data from the host computer, An attribute storage unit for receiving and storing the attributes of the still image data stored from the host computer, and an original image dot number DX, DY,
Original image character counts CX and CY, and resolution X at the display terminal
/ DX, Y / DY and the aspect ratio A in the display terminal
The image processing apparatus includes a calculation unit that multiplies Y / AX and AY / AX, and an enlargement / reduction processing unit that enlarges or reduces still image data stored in the still image data storage unit by an output of the operation unit. A still image data management method is disclosed in which the relative size of a display image based on image data created by different models is the same regardless of the type of display.

In Japanese Patent Application Laid-Open No. Hei 4-291675, when operating as a terminal of a host computer,
Since the number of characters on the screen is the same for all models, the display start position of the image (upper left corner of the screen) is managed in units of characters, and the number of dots in the image display area is calculated based on the size of each character. However, the coordinate management method cannot handle different display data.

For example, Japanese Patent Application Laid-Open No. 8-44885 discloses an apparatus for displaying display data of a virtual screen on a real screen, in which the same size is displayed on real screens having different resolutions without changing the coordinate transformation of an application. As an apparatus, means for calculating a display magnification for displaying display data on an actual screen, a display position calculated by calculation of a dot position to be displayed according to the display magnification, and a display position selected from a plurality of dot position candidates A fraction processing means for allowing an operator to input a relationship between two dot positions as directions and performing fraction processing based on the input direction; and a means for displaying display data on an actual screen based on a result of the fraction processing means. A display device having the same has been proposed. In this display device, when there is a remainder after dividing the display data of the virtual screen by the display magnification (the resolution of the virtual screen is divided by the resolution of the real screen), the remainder is calculated by X coordinate, Y coordinate, rounding up, rounding down, or the like. Then, fraction processing is performed.

Accordingly, the present invention has been made in view of the above problems, and a main object of the present invention is to always provide a screen and components within the screen without depending on the resolution of the screen to be output. It is another object of the present invention to provide a method, an apparatus, and a recording medium that enable a screen to be displayed on a screen at a fixed size, and that can display a fixed part content in a screen area.

[0010]

The device information at the time of design is obtained from the resource, and the ratio between the resolution at the time of design and the resolution of the execution environment in which the display is executed is calculated. When the coordinate unit is a point value (character unit), Design-time DPI (Dots P
er Inch; the number of dots per inch) in the coordinate conversion information section, including the value, and the display resources are developed into actual display resources for display on an output device. Coordinate information conversion means for converting the position and size information of the component into an absolute value on the coordinate system of the device to be output based on the information of the coordinate conversion information section to obtain actual display resource information; Display data output means for making an output request to the output device based on resources.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the configuration of one embodiment of the present invention.

Referring to FIG. 1, one embodiment of the present invention is:
It comprises a display resource 100, a display data processing device 110 that operates under program control, and an output device 120 such as a display device or a printing device.

The display data processing device 110 includes a coordinate conversion information acquisition unit 111, a coordinate conversion information unit 112, a coordinate information conversion unit 113, an actual display resource 114, and a display data output unit 115.

Each of these means operates as follows.

The coordinate conversion information obtaining means 111 obtains device information at the time of design (information of the device that designed the display resource) from the display resource 100,
The ratio with the resolution of the execution environment is calculated, and if necessary, such as when the coordinate unit is a point value, the information is stored in the coordinate conversion information unit 112 including the DPI value at the time of design and held.

The coordinate information conversion means 113 develops the display resources into the actual display resources 114, and at this time, the position,
A value obtained by converting the size information into an absolute value based on the information held in the coordinate conversion information unit 112 is developed.

The display data output means 115 issues an output request to the output device 120 based on the actual display resources 114.

FIG. 2 is a flowchart for explaining the operation of one embodiment of the present invention. The operation of the embodiment of the present invention will be described in detail with reference to FIGS.

First, the coordinate conversion information obtaining means 111 obtains the design resolutions AX and AY (resolutions in the X and Y directions) from the display resources, and executes the resolutions BX and BY (X and Y) at the time of execution.
The ratio is calculated and the ratio is stored in the coordinate conversion information unit 112 (step A1 in FIG. 2).

Next, a coordinate unit is obtained from the display resource 100. If the coordinate unit is a point value (character unit), the DPI value is also stored in the coordinate conversion information unit 112 (step A2). If the coordinate unit is a dot, the DPI value is not stored. In one embodiment of the present invention, it is possible to cope with a case where the display data is not only a dot value but also a point value.

Next, the display resources are supplied to the coordinate information converting means 113, and the coordinate information converting means 113 expands the display resources 100 into the actual display resources 114. The actual display resource 114 is developed in the memory. At this time, the processing of steps A4 to A8 is performed until the display data ends. That is, the processing of steps A4 to A8 is repeated until it is determined in step A3 that the display data is completed,
If it is determined in step A3 that the display data is completed,
It branches to step A9.

If the display data is coordinate data (YES in step A4), the value of the coordinate data is converted based on the information held in the coordinate conversion information section 112.

At this time, if the unit of the coordinate data (position information and size information of width and height) of the parts and the like on the screen is a point value (character unit) (YES in step A5),
From the DPI value held in the coordinate conversion information unit 112,
The position and size information specified by the point value is calculated as the absolute value (temporary absolute value) in dot units at the original resolution (step A6).

When the display data is coordinate data,
The coordinate data (width, height, position) in dot units is multiplied by the ratio of the resolution, and converted into absolute values on the coordinates of the display screen of the device to be output (step A7).

Develop to actual display resources (step A
8) When the display data ends, the display data output means 1
15, and the display data output unit 115 issues an output request to the output device 130 in accordance with each display data (step A9).

Next, an embodiment of the present invention will be described using a specific example.

As shown in FIG. 3, for example, 1024 × 7
68-resolution terminal, 1/4 of screen (real screen)
Design a screen of the size, this is 800 × 600 resolution
On the terminal screen.

In the display resource 100, as information necessary for the coordinate transformation, the resolution value of the device at the time of design is “1024 × 7”.
68, a screen width “512”, a height “384”, and a position “0,0”.

The coordinate conversion information acquisition means 111 calculates the ratio from the resolution value "1024 × 768" and the resolution "800.times.600" of the device in the execution environment.

As a result, information of the width ratio “0.78” and the height ratio “0.78” is stored in the coordinate conversion information section 112 (step A1 in FIG. 2).

Next, a coordinate unit is acquired, and in this example, since dot designation (not point designation), D
The PI value is not stored (step A2).

Further, the display resource 100 is read, and
When the display data is coordinate information (width, height, position), each of the width and height is multiplied by the corresponding resolution ratio (width 512 × 0.78, height 384 × 0.78). , As a result, width “399”, height “300”, position “0,0”
Is calculated (step A7).

Finally, a request to output a screen is sent to the output device 120 with the size and position (step A9).

As a result, even in an apparatus having a resolution of 800 × 600, a screen having a size １ ／ of the screen is displayed. In one embodiment of the present invention, coordinate conversion is performed for each of the components on the screen based on the position and size information, so that the content of the components that can be displayed on the screens of the devices having different resolutions does not differ.

[0042]

As described above, according to the present invention,
Screen display resources created based on a certain resolution can support the equivalent image display at multiple resolutions. As a result, there is no need to prepare screen display resources for each resolution, and development and maintenance This has the effect of reducing man-hours and the number of assets.

The reason is that, in the present invention, a coordinate conversion reference is provided by the coordinate conversion information acquiring means for a screen resource held at a value depending on the environment at the time of design, and the coordinate information conversion is performed based on the reference value. This is because the means does not need to prepare a plurality of screen display resources to convert to a form depending on the execution environment. According to the present invention, there is also an advantage that it is possible to support a plurality of coordinate management methods of the image display resource.
