Description

Method for editing decoration effect on figure object in wordprocessing-program and device example}

The present invention relates to a method for editing a figure object in a document editing program, and more particularly, after adding a figure object of a vector type and adding a property of a decorative image of a raster type to a conventional editing method, the image is more beautifully added. The present invention relates to a method that can be edited and a terminal using the same.

Computers store and represent graphic data (pictures, photos, images) in two ways: raster (Raster or bitmap, hereinafter referred to as raster) and vector (Vector). .

 The raster expresses image information using a two-dimensional array of small dots. The small points that make up the picture are called pixels (picture elements), and the picture is formed by the RGB color value or brightness value of each point.

In other words, the Lester method depends on the concept of resolution. In this case, the resolution is created in the same way as a mosaic in a certain area. As the number of pieces constituting the mosaic increases, the quality of the picture increases, on the contrary, the wider the area represented by the same number of pieces, the lower the quality of the picture. .

In other words, the higher the resolution, the larger the number of particles, or "pixels," and the lower the resolution, the smaller the number of "pixels." Likewise, when you see a picture on a screen larger than the resolution initially set, the picture quality is lowered. When you view a picture on a smaller screen, the picture quality is higher. The pictures we usually use on the Internet or on computers are all Lester images. Images imported into a digital camera or scanner are also raster images.

The Lester image has the advantage that the pixels of different colors can be combined to express deep color tone and smooth texture, so that all the visible images can be expressed. In addition, the larger the number of dots (pixels) used, the more powerful is the ability to draw a picture more realistic.

However, the disadvantage is that the image is damaged by zooming or transforming the image. Also, the raster image only stores the resulting pixel values, and the various properties used for editing are not saved / modified. So, with the raster, I drew a red rectangle, but to change it back to a circle, you need to delete the rectangle that was already drawn and redraw it from scratch, rather than changing the rectangle's properties to a circle.

On the other hand, vector graphics store and express image information as a combination of objects that are components of graphics such as lines, planes, arcs, circles, curves, and polygons. That is, it consists of geometric elements, not pixels. In other words, you can reconstruct the picture with key points and attributes (for example, line length, thickness, and color) of each object. In the case of using vector graphics, it is easy to express geometric figures, but it is appropriate to express them by using raster graphics in the case of a figure having less delicate geometric parts such as a portrait.

The vector type image does not change the size of the file at all, even if it is enlarged or reduced, and does not become damaged or rough. Therefore, in the case of the curved image, the raster type image continues to be circular even when the image is enlarged, unlike the step phenomenon. It is possible to maintain the form of.

Therefore, when using graphic objects in a text editing program, vector shapes such as rectangles or circles are used.

In the case of a document editing program, printing is often performed due to its characteristics, because when a graphic object is used in a raster method, an image included in a document may be broken by a stair phenomenon, depending on the print size.

FIG. 1 is a diagram illustrating a state in which an image is added in a text editor according to an exemplary embodiment.

As shown in FIG. 1, a user first selects an image to be added in the document editor, and then selects a position in the document window and inserts the image into the document by dragging.

2 is a diagram illustrating a state in which an image of a vector type added in a document editor is edited according to an exemplary embodiment.

As illustrated in FIG. 2, after adding a vector image, the user may edit the image to transform the image into a desired shape.

As described above, the vector image generates a line and a face by representing the image by a mathematical functional relationship connecting the points to the points.

Each object, which is a component of a vector image, has its own characteristic values of color, shape, outline, size, and position on the screen. Editing a vector image is to modify properties of such data. Therefore, there is a decisive disadvantage in that the enlargement and reduction are free, but the various aspects cannot be expressed in the editing.

That is, in the related art, only the properties of the base image, that is, the length, thickness, and color of the base image may be edited in the edit window of the base image. This is inevitable due to the nature of the vector image. Accordingly, in most text editing programs, the color of the line constituting the figure object, the thickness of the line, the type of the line, or the inside of the figure object is filled with a specific color, It only provided functions such as gradation, fill, texture (picture tile) fill, and pattern fill.

As shown in FIG. 2, only the editing of the size of the vector image, the thickness and color of lines constituting the vector image is possible. Especially in the case of the inside of a vector image, there is a limitation that only monotonous expression is possible by filling a specific color, gradation, painting, texture, and pattern.

Therefore, a user who wants to add a three-dimensional spherical image to the document is expressed using a gradient as shown in FIG. 2, but the beautiful image desired by the user is impossible due to the structural limitation of the vector image. In addition, it is impossible to decorate a figure of a vector method that is already created with certain patterns (company logo, name of a person, star, heart, etc.).

The present invention has been made to solve the above problems, an object of the present invention, in the use of a document editing program, according to the structural characteristics of the vector image in the editing after inserting the conventional vector image In addition to editing lines and fills, the present invention provides a text editing program that enables the insertion of more beautiful images by adding more decorative images as attributes.

The present invention has been made to solve the above problems, an object of the present invention, in the use of a document editing program, according to the structural characteristics of the vector image in the editing after inserting the conventional vector image In addition to editing lines and fills, the present invention provides a text editing program that enables the insertion of more beautiful images by adding more decorative images as attributes.

Hereinafter, with reference to the drawings will be described the present invention in more detail.

3 is a flowchart used to explain a method of adding a decoration image to a figure object according to an embodiment of the present invention.

First, the user executes a document editing program, and then loads a new document or an existing conventional document. If a specific image, such as a triangle or rectangle, or a line drawing is required while working on the document, the image is selected using a menu such as a drawing of a document editing program (S310). The selected image is called as a figure object below.

As described above, the picture used in the document editing program is a vector image. In the case of a text editing program, printing is often performed, because when a raster-type image is put on a document, the image included in the document may be broken by a stair phenomenon, depending on the size of the printing. When the user selects the figure object, the figure object is displayed on the document window using a mouse drag and the like (S320).

After that, the user displays an editing window for editing the basic image (S330).

Unlike the related art, the present invention adds a new decoration item to the edit window to display a new decoration image display window through the menu. After that, the user selects a decoration image he wants to add to the figure object (S340).

The selected decorative image is added to the figure object and synthesized (S350).

There are many ways to synthesize the decoration image on the figure object which is the vector image, but in general, a lot of overlay methods are used.

As described above, the vector-based image draws a picture based on the recalculated information based on the geometric data on the transformation (transformation) such as movement, size, and rotation, so that accurate results can be output even for the deformation. It has advantages An overlay method is used to synthesize the vector data with the raster, and the overlay is performed by using a blend function between two raster data as follows.

C = f (B, D)

Where f: Blend function

        B: Pixel value of image 1-(vector geometry image)

        D: Pixel value of image 2-(Decorative image)

        C: Combined pixel value of images 1 and 2

On the other hand, it is possible to adjust the transparency of the decorative image when compositing between the two images by using the blend function as follows in consideration of the alpha (alpha) characteristics at the time of the synthesis.

1. Balpha = B.alpha;

2. Dalpha = D.alpha * alpha;

3.Calpha = 65025-(255-Balpha) * (255-Dalpha);

4. a1 = 255 * Dalpha;

A2 = (255-Dalpha) * Balpha;

6.Cred = (D.red * a1 + B.red * a2) / Calpha;

7.Cgreen = (D.green * a1 + B.green * a2) / Calpha;

8.Cblue = (D.blue * a1 + B.blue * a2) / Calpha;

9. C = ARGB (Calpha, Cred, Cgreen, Cblue);

Where alpha is the transparency you want to apply to the decorative image. 0 is completely transparent, 1 is opaque

        B: Pixel value of image 1-(vector geometry image)

        D: Pixel value of image 2-(Decorative image)

        C: Combined pixel value of images 1 and 2

ARGB: alpha, red, green, blue pixel functions

Step 2 in the calculation process adds a separate transparency value alpha to the transparency value of the D Lester image used as the decoration image so that the decoration image can be synthesized to the transparency desired by the user. Step 3 determines the transparency of the final synthesized raster image.

Steps 4 through 5 determine the weighted transparency values to be applied to B and C.

In steps 6 to 8, red, green, and blue components are synthesized by applying weighted transparency values.

Finally, in step 9, the final pixel value is calculated from each component.

Of course, the synthesis example is just an embodiment, and various functions may be applied in addition to the blend function.

In order to synthesize a decoration image on a vector-based figure object, the figure object should be rasterized as described above. In other words, in order to synthesize a vector shape and a raster decorative image, vector data must be rasterized to extract pixel values. When rasterizing a vector shape as described above, the characteristics unique to the vector are lost, and the size, rotation, etc. are changed. Stair phenomena such as sea raster images occur and the quality of the picture is degraded.

Therefore, in the present invention, the synthesized data obtained by synthesizing the vector figure and the raster image and the vector figure and the raster image data before synthesis are respectively stored separately. That is, after combining the decorative images of the vector figures and storing the synthesized data, stair phenomenon like the raster image occurs when the vector figures are rotated later. Accordingly, even after combining, the vector-shaped figure and the decorative image information are stored separately in a storage medium such as a hard disk, and the synthesized image, that is, the image information synthesized by rasterizing the vector figure as described above, is cached. Store in

Thereafter, the synthesized image stored in the cache is displayed (S360).

Instead, if you change the size, rotation, etc., or other vector-specific properties of the vector shape later, it is not converted directly from the synthesized image displayed on the screen. Reload and perform each change, then recombine and save.

Of course, the above process is not performed every time a change is made to the vector figure. For example, when the name and ID for simple management of the figure object are changed, the cache is not deleted and the size of the figure object is changed and rotated. Only when the attributes that affect drawing, borders, fills, etc. are modified, the cache is deleted and the above process is performed again.

In case of decorative image, it uses raster image unlike vector object. As described above, in the case of a figure object, since a vector image is used, there is a limit to the user's beautiful design. Accordingly, in order to make it more beautiful, the decorative image inserted in the middle uses a raster image that is easy for the user to decorate intuitively and beautifully.

Since the decoration image is included in the inside of the figure object, even if the interpolation technique is applied to the edge of the decoration image, there is no aesthetic problem because it is interpolation between the edge of the decoration image and the inside of the figure object, that is, between images. The image may use the raster method, and the border of the decorative image may use an interpolation technique so that the stairs may not be easily seen.

One embodiment of the decorative image display window is shown in FIG. As shown in FIG. 4, when the user selects a circle as a figure object and selects one of various decoration images through the decoration image, the selected decoration image is displayed on the figure object.

As shown in FIG. 4, if the user wants to add a three-dimensional spherical image to the document window, first select a menu 420 such as Draw from the menu and select a circular figure object to display the figure object 430 in the document window. After drawing), the edit window 440 is displayed.

If you select an item called decoration 450 in the edit window, a number of decoration images that can be added to the corresponding figure object are displayed. A plurality of decorative images applicable to each figure object, that is, a line, a rectangle, a circle, etc. are provided in advance, and the figure objects and the decoration images are matched with each other and stored, and then displayed as only the decoration images applicable according to the figure objects. When the user selects any one of the decorative images 460, the decorative image 435 is displayed on the figure object 430, and both images are synthesized and then displayed as one image. Therefore, after the deformation to the figure object 430, the synthesized decorative image 435 is also deformed in synchronization with the deformation. In other words, rather than simply adding a decorative image to a figure object, it is considered that a new property of a figure object is newly created.

5 is a diagram illustrating a state in which a decorative image is added to an edited figure object according to another exemplary embodiment of the present invention.

As described above, the decorative image is added to the figure object, and at the same time, a gradation or the like which is a conventional editing function can be applied. That is, as shown in FIG. 5, a gradation is given to the figure object 530, and a decorative image is added thereon. At this time, it is also possible to synthesize the decoration image in a general overlay method, that is, overlapping method as shown in FIG. 4, but also to synthesize the decoration image using a mask method as shown in FIG. 5.

In addition, a decoration image editor function may be added to allow a user to freely create a decoration image, and to add it to the decoration menu. In addition, it is also possible to add the option to control the transparency of the decoration image at the time of synthesis to make the decoration image translucent and synthesize the figure object.

In the present embodiment, the decorative image is described in the case of the raster, but of course, the decorative image may be created in a vector manner (path, brush, etc.).

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
