摘要： A method and apparatus for converting multi-level raster shapes into bi-level raster shapes while preserving as much of the visual character of the shape is disclosed. The method and apparatus solve two main problems arising in the task: that of broken continuity (drop-outs) and that of large changes in the width of horizontal and vertical lines on the bi-level raster shape as a result of minute changes on the multi-level shape (stem width aliasing). Drop-outs are handled by identifying certain boundaries between pixels as drop-out warnings. Pixels adjacent to dropout warnings have their coverage values converted from multi-level to bi-level by a process that guarantees that at least one of them will be rounded up. Dropout warnings are found from the outline of the ideal shape used to generate the multi-level shape and represent an approximation to said outline. In a preferred embodiment, the set of drop-out warnings for an outline is the set of pixel boundaries containing the nearest pixel boundary to each intersection of the outline with mid-pixel lines. Stem width aliasing occurs because of rounding errors clustering along horizontal and vertical lines. The present invention minimizes stem width aliasing by a variable threshold technique in which the threshold value used to turn the multi-level coverage value of a pixel into a bi-level value depends on the pixel position. The multiple threshold values are used to scatter the rounding errors over neighboring pixels so that they do not cluster along horizontal or vertical lines and are therefore less apparent to a viewer. In a preferred embodiment, two different threshold values are used in a checkerboard pattern, i.e., the threshold value for every other pixel in the horizontal or vertical direction alternates between the two values.

摘要： A printer device includes a bit map memory for storing bit map data of one character, an intermediate data generator, an intermediate data storing area, a development unit, and a printer. The intermediate data generator generates intermediate data having information representing the presence/absence of an edge line of a character and positional information of the edge line every dot-scan line from outline data consisting of coordinate value data. The intermediate data storing area updates and stores the generated intermediate data every dot-scan line. The development unit sequentially develops bit map data in the bit map memory every dot-scan line on the basis of the stored intermediate data. The printer prints the character on the basis of the bit map data of one character developed and stored in the bit map memory.

摘要： The present invention provides a process for compensating for error in the position of characters in a character string that can result from printing text data intended for a printer having one resolution on a printer having equivalent fonts, but a different resolution. The method comprises the steps of determining the conversion error for a character in a string of characters, accumulating the conversion error, determining whether the accumulated conversion error equals or exceeds a predetermined threshold value, positioning the next character in the string from the present character by the amount of the predetermined threshold value and decrementing the accumulated conversion error, provided the accumulated conversion error equaled or exceeded the predetermined threshold value, and repeating the above steps for the next character in the character string. The invention further includes the additional steps of examining character strings occupying the same baseline for instances in which a relative move of one character string abuts a relative move or a space character of another character string, and in such instances replacing the relative move and the abutting relative move or space with an equivalent relative move.
摘要翻译：本发明提供了一种用于补偿字符串中字符位置的错误的过程，该字符串可能由打印机上打印具有相同字体但具有不同分辨率的打印机的打印机的打印文本数据而产生。该方法包括以下步骤：确定字符串中的字符的转换错误，累积转换错误，确定累积转换误差是否等于或超过预定阈值，将下一个字符从当前字符定位到字符串中，如果积累的转换误差等于或超过了预定阈值，并且对于字符串中的下一个字符重复上述步骤，则预定阈值的量并减少累积的转换误差。本发明还包括检查占据相同基线的字符串的附加步骤，其中一个字符串的相对移动与另一字符串的相对移动或空格字符相对移动，并且在这种情况下，替换相对移动和邻接相对移动或相对移动的空间。

摘要： A data converting apparatus for converting outline data of a character into dot data including dot-forming bits each indicative of an image dot to be formed at a position of a corresponding dot-forming picture element which lies within the outline of each stroke of the character, when the character outline is superimposed on a pixel screen wherein picture elements are defined by x-axis and y-axis pixel lines perpendicular to each other. The apparatus includes a device for changing width direction data indicative of a direction of a nominal width of each stroke, if the outline data of the character are subjected to a conversion for rotation or italicization of the character as represented by the converted outline data. The width direction data is changed depending upon the specific condition of the outline data conversion, before at least one of two segments of the character outline which define the width of the stroke is moved in the direction indicated by the width direction data so that the reproduction width of the rotated or italicized character is equal to the nominal width.

摘要： A data converting apparatus for converting outline data representative of an outline of a character, into dot data including dot-forming bits each indicative of the presence of an image dot to be formed at a position of a corresponding dot-forming picture element which lies within the outline of each stroke of the character, so as to satisfy a predetermined requirement, when the outline of the character is superimposed on a pixel screen wherein picture elements are defined by x-axis pixel lines and y-axis pixel lines perpendicular to the x-axis pixel lines. The apparatus includes a device for determining whether or not a difference between an outline width of each character stroke as defined by the outline data and a reproduction width of the as reproduced according to the dot data as normally prepared based on the outline data exceeds a reference value. The normally prepared dot data are changed so as to reduce the difference between the outline and reproduction widths, if the difference exceeds the reference value.

摘要： There is provided a pseudo-halftone image expression method capable of processing vector data with an excellent image quality and small computational complexity. Gray levels of n×n/m are expressed by varying the number of formed dots within a matrix of n×n dots on an m-dot basis (where n denotes an integer of 8 or more and m denotes an integer of 4 or more). A dot formation rule corresponding to each gray level within a matrix is divided into at least two stages, form a low gray level to a high gray level. In a first stage, dots are arranged at random and in dispersion so as to separate a dot from each other. In a second stage, dots are extended in random directions in turn so as to prevent an island of successive dots from coupling with each other using the dots arranged at the first stage as a nucleus.
