Description

TECHNICAL FIELD The present invention relates to a reduced character processing method, and more particularly to a reduced character processing method for outputting a character pattern reduced at a desired reduction ratio.

[Prior Art] In order to output a character with a desired character size, some operators have selected a character set capable of outputting a character with the desired character size. However, the device capable of selecting such a desired character set is based on the idea that the operator himself / herself may select a character set suitable for the reduced output character size when the image is reduced and output.

Therefore, the operator checks the character size of the currently selected character set, calculates the character size when the character size is reduced at the desired reduction ratio, and then specifies the obtained reduced output character size again. It required a very complicated operation that had to be done.

In the case of processing characters as an image, the reduction ratio is input as the degree of reduction of the document, and the image to be reduced input as an image is reduced and edited at that reduction ratio. A large amount of memory is required to store the image, and if the reduction ratio is large, the image quality after reduction is poor.

[Problems to be Solved by the Invention] However, it is easier for the operator to input the reduction ratio of the original document as it is, rather than to calculate and specify the character size after reduction, which is easier to specify. However, a printer that prints using a character set does not have a function of selecting an appropriate character set to output a document in response to designation of a reduction ratio.

Also, rather than inputting an image to be reduced and outputting an image created by editing the image at a specified reduction ratio, an original is created using the stored character set,
The output saves the memory for storing the image for editing, and the printing using the character set is preferable in terms of the memory saving of the apparatus.

Therefore, the object of the present invention is, based on the situation described above,
It is to provide a reduced character processing method that is convenient for both the operator and the device.

[Means for Solving the Problems] In order to achieve the above object, the present invention stores a character size of a selected character set, inputs a character reduction rate, and stores the stored character size in the above-mentioned manner. Calculate the reduced output character size when reduced by the input reduction ratio, and from the stored multiple character sets with different character sizes, select the character set with the character size corresponding to the obtained reduced output character size. It is characterized by selecting.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an example of an apparatus for carrying out the reduced character processing method according to the present invention, which will be described in detail below.

In FIG. 1, 1 is a storage means for storing attributes such as height and width of a character currently selected and used, 2 is a reduction rate designating means for designating a reduction rate of a character, and 3 is a storage means. 1 and a calculation means for calculating the size of the reduced character from the information of the reduction ratio designating means 2, 6 is a character set corresponding to the size of the character calculated by the calculation means 3, and a plurality of types of character sets are stored. Select from the character set storage means,
It is a character set selection means, and the reduced image is displayed or printed using the character set selected by the character set selection means. The character set selecting means 6 selects a character set corresponding to or closest to the character size calculated by the calculating means 3 from the character set storing means, and the selected character has a designated reduction ratio. If not, the correction reduction means 5 corrects it and reduces it.
Have and. The correction reduction means 5 is unnecessary when the selected character matches the designated reduction ratio.

Next, FIG. 2 shows a flowchart of character processing when the reduction ratio is designated by the reduced character processing device of the present invention. For simplification of explanation, the size of each character is square and the reduction designation is also square reduction. Also, although an example of printing will be described, reduced character processing for display can be similarly performed. As shown in FIG. 2, in step 1, the reduction ratio is designated by the reduction ratio designating means 2 through the input line. Then in step 2,
Currently selected in the storage means 1 by the calculation means 3,
The size information is calculated by multiplying the width and height information of the character set information being used by the reduction ratio. Then, in step 3, the character set storage means is checked by the character set selection means 6. If the character set storing means has a corresponding size, proceed to step 4 and rewrite the reduced character set area for printing in the character processing device to the corresponding character set so as to prepare for the reduced printing. 5
In step 1, the printing rate concerning the width and height is set to 1. This indicates that there is no need to reduce the size when printing later. If the character set storing means does not have the corresponding size in step 3, the process proceeds to step 6, and the width and height are selected in order to select a character set close to the width and height information calculated in step 2. A character set closest to the height information and having a size larger than the width and height information is selected from the character set storage means by the character set selection means 6, and the reduced character set area of the character processing device is selected. Information is rewritten, and in step 7, the ratio of the reduced width and height calculated in step 2 to the size of the character set selected in step 6 in the height and width directions is set as the print ratio in each direction in preparation for reduced printing. .

Next, FIG. 3 shows a flowchart of the pre-processing prior to printing. The pre-process prior to this printing is performed after the process of selecting the character set used for printing and the process of setting the printing rate shown in the flowchart of FIG. 2, and when a character set that does not actually match the reduction ratio is selected, This includes the work for creating a reduced character by the character set selecting means 6 using the character set.

First, in step 11, the size (width: x, height: y) of the reduced character calculated in step 2 of FIG. 2 is obtained, and then in step 12, step 4 or step 6 of FIG.
The character set information (width: m, height: n) selected in the reduced character set area is obtained in step 13 and it is checked in step 13 whether or not both are the same (size) character (same if print ratio is 1). If they are the same, the selected character set information is adopted as it is, and if they are not the same, proceed to step 14 (l
−1) / l≈x / m, l such that (l′−1) / l′ ≈y / n,
Find l '. Then proceed to step 15, where -1 dot in 1 dot in the horizontal direction and-in 1'dot in the vertical direction.
Characters are composed by reducing dots.

Actually, for convenience of printing quality, for example, one character is divided into 1 × 1 (when square basic pattern is squarely reduced) blocks for one character, and a dark line is left in the block. Create a letter in the direction that leaves a thin line on. For example, when there is a pattern as shown in FIG. 4 (1), first, as shown in FIG. 4 (2), a darker line is left for each vertical axis, and then as shown in FIG. 4 (3). In the same way, leave a thinner line for each wack in the lateral direction.

In Fig. 5, as an example, when a character set of 32x32 dots is reduced to 1/2 to a character set of 16x16 dots, and there is no such character set, a character set of 24x24 dots is selected. The character reduction mode of is shown. That is, since l = 3, the reduction is 3
It can be seen that it is sufficient to thin one dot.

According to the present invention, square reduction can be performed using a square basic pattern, and not only the length reduction and the flat reduction but also the non-integer multiple reduction can be performed by reducing the length and width separately. Further, if a more improved algorithm is used instead of the algorithm of this example, the printing becomes clearer.

According to the above-mentioned embodiment, since it corresponds to all the sizes required by the combination of the reduction ratio designated using the character set of the typical size stored in advance and the character size set in the document, Saves memory required to store character sets.

[Effects] As described above, according to the present invention, it is possible for an operator to output a high-quality reduced original using a character set by designating a reduction ratio that is easy for the operator to intuitively understand.

As described above, according to the present invention, since the original is created using the stored character set, the memory for storing the image can be saved more than inputting and editing the original image to be reduced.

As described above, according to the present invention, it is possible to provide a reduced character processing method that is convenient for both the operator and the apparatus.
