Abstract

PURPOSE:To obtain a good printing result, by smoothing a magnified character based on a dot matrix type font by vicinal four-point comparison. CONSTITUTION:This system is constituted of a master control part 1, a program ROM 2, an RAM 3, a dot matrix pattern ROM 4 and a printing control part 5. Smoothing processing is performed by the control from the master control part 1. Now, when Y=(AXB)X(CXD) is operated noticing four points A, B, C, D with respect to a Y-part in an X-direction, Y=(0X0)X(1X1)=1 holds. When Y=1 is obtained by this logical formula, a dot is added and, when Y becomes 0, no dot is added. In the same way, operation is performed in the other three directions. As mentioned above, by the vicinal four-point comparison of an magnified character, a good printing result can be obtained.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、プリンタの装飾文字、特に拡大文字平滑方式
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to decorative characters for printers, particularly to an enlarged character smoothing method.

〔従来の技術） 従来のプリンタにおいて、拡大文字フォントを有さない
場合には、通常フォントを拡大して拡大フォントを作成
し、その拡大フォントに対して平滑化操作を行なわねば
ならない。従来、平滑化する場合、近傍２点比軸で平滑
化していた。[Prior Art] If a conventional printer does not have an enlarged character font, it is necessary to enlarge a normal font to create an enlarged font, and then perform a smoothing operation on the enlarged font. Conventionally, when smoothing was performed, smoothing was performed using a ratio axis of two neighboring points.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

従来の２点比較による平滑化では、直角な線まで平滑化
してしまい、良好な印字結果が得られない。In the conventional smoothing based on two-point comparison, even perpendicular lines are smoothed, making it impossible to obtain good printing results.

〔課題を解決するための手段〕[Means to solve the problem]

本発明によれば、ドツトマトリックス型フォントによる
拡大文字を、近傍４点比較により平滑化することを特徴
とするプリンタの拡大文字平滑方式が得られる。According to the present invention, there is provided an enlarged character smoothing method for a printer, which is characterized in that enlarged characters in a dot matrix type font are smoothed by comparing four neighboring points.

〔実施例〕〔Example〕

次に、本発明の一実施例を示した図面を参照して、本発
明をより詳細に説明する。Next, the present invention will be described in more detail with reference to the drawings showing one embodiment of the present invention.

第１図を参照すると、本発明の一実施例は、マスク制御

トリックスパターンＲＯＭ４と、印字制御部５とから構
成されている。Referring to FIG. 1, one embodiment of the present invention is comprised of a mask control section 1, a program ROM 2, a RAM 3, a dot matrix pattern ROM 4, and a print control section 5.

第２図は、文字電′のドツトマトリックスパターンを示
したもので、ドツトマトリックスＲＯＭ４に格納されて
いる。第３図は第２図のパターンを単純に縦横２倍した
もので、ＲＡＭ３に格納される。FIG. 2 shows the dot matrix pattern of the character phone, which is stored in the dot matrix ROM 4. FIG. 3 shows the pattern in FIG. 2 simply doubled in height and width, and is stored in the RAM 3.

第４図は、第３図の一部分を抽出したもので、マスク制
御部１からの制御により、次のような平滑化処理が行な
われる。FIG. 4 is a partial extraction of FIG. 3, in which the following smoothing process is performed under control from the mask control section 1.

いま、第４図において、Ｘ方向からＹの部分に関して点
Ａ、Ｂ、Ｃ，Ｄの４点に着目し、Ｙ＝（］コ「ｒ）ｘ（
ＣｘＤ） を演算すると、 Ｙ＝（ＯＸＯ’）Ｘ（ＩＸＩ）＝１ となる。Now, in Fig. 4, focusing on the four points A, B, C, and D regarding the portion Y from the X direction, Y=(]ko'r)x(
CxD), Y=(OXO')X(IXI)=1.

この論理式にて、Ｙ＝１となれば、ドツトを付加し、０
となれば、ドツトを付加しないようにする。In this logical formula, if Y=1, add a dot and add 0
If so, do not add dots.

同様にして、他の３つの方向から演算することにより、
第５図の結果を得ることができる。Similarly, by calculating from the other three directions,
The results shown in FIG. 5 can be obtained.

〔発明の効果〕〔Effect of the invention〕
