PURPOSE:To increase the flexibility of an output by constituting the device so that whether image data is subjected to dot density conversion in accordance with dot density of an output device or not can be selected. CONSTITUTION:In the case 'dot density conversion is executed' is set, an enlargement ratio conforming to dot density of a FAX is delivered to a dot density converting part, image data of 160dpi, 180dpi is converted to image data enlarged to dot density of 200dpi, and thereafter, stored in a density conversion data store area 53 in a storage part 5, and compressed image data is stored in an image compressed data store area 54. In the case 'dot density conversion is not executed' is set, image data obtained by compressing the image data in an image data store area 52 in the storage part 5 is stored in the image compressed data store area 54. Thereafter, the image data in the image compressed data store area 54 is transmitted directly to a FAX 7 by using an image data output part 70 and a communication control part 65.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a document editing section 9 that edits documents; an image data generation section that generates the edited document as image data; The present invention relates to a document creation device that includes a dot density conversion section that performs conversion, and an image data output section that outputs image data to an output device.

[Conventional technology]

In the conventional technology, for example, Document Word Processor Super 3000 (hereinafter Super 3000) manufactured by Hitachi, Ltd.
), it is necessary to set the output device (printer type 2 dot density) for each document, and image data cannot be output (printed) to any device other than the output device (printer) set for the document. When outputting image data to another output device, it is stated in the operating manual Function Section I that it is necessary to change the output device set for the document.

This is because if the dot density set for the document is higher than the dot density of the output device, the image output from the output device may be larger than the actual size and may extend beyond the output paper. This is because if the dot density set for the document is smaller than the dot density of the output device, the image output from the output device will be smaller than its actual size.

[Problem to be solved by the invention]

However, the conventional method has the following problems.

Document creation devices that use a method similar to the Super 3000 need to enlarge or reduce the image data to match the dot density of the output device in order to output the image data to an output device other than the output device set for the document. There is.

However, compared to the case where the dot density of the output device set for the document and the dot density of the output device that outputs the image data are the same, it is necessary to enlarge or reduce the image data to match the dot density of the output device. , it takes time to generate the image data, and since the image data is enlarged or reduced, unnecessary dots are inserted and dots are omitted compared to the image data before dot density conversion, and the image data is There is a problem with quality deterioration.

An object of the present invention is to provide a density conversion selection means that can select whether or not to perform dot I/density conversion on image data according to the dot density of an output device, and to perform dot I/density conversion by the density conversion selection means. When selected, the image data with the dot density set for the document is changed to the driver I/O that matches the dot density of the output device.
By converting the image data into a density, the image data is output to an output device in a normal font size.If the density conversion selection means selects not to perform dot density conversion, the dot density set in the document is To shorten the generation time of image data to be output to an output device by outputting the image data to the output device without converting the image data to a dot density that matches the dot density of the output device.
And, it is an object of the present invention to provide a document creation device that can easily perform the following operations according to the user's selection: preventing deterioration in the quality of image data due to dot insertion and data omission.

[Means to solve the problem]

The above object is achieved by the following means.

(1) A density conversion selection means is provided which can select whether or not to perform dot density conversion on image data in accordance with the dot density of the output device.

(2) When dot density conversion is selected by the density conversion selection means, the image data is converted to a dot density that matches the dot density of the output device by converting the image data of the dot density set in the document. If it is selected to output the data to the output device in the normal font size and not to perform dot density conversion using the density conversion selection means, the image data with the dot density set for the document is converted to the dot density of the output device. A means for outputting to an output device without converting the dot density to a dot density corresponding to the dot density is provided.

[Effect]

The user uses the density conversion selection means to set whether or not to perform dot density conversion on the image data in accordance with the dot I-density of the output device.

When dot density conversion is selected by the density conversion selection means, the image data is converted to a normal dot density by converting the image data with the dot density set in the document to a dot density that matches the dot density of the output device. Output to the output device in font size.

When not performing dot density conversion is selected by the density conversion selection means, the image data of the dot density set in the document is output to the output device without converting it to a dot density that matches the dot density of the output device. .

As a result, when not performing dot density conversion is selected by the density conversion selection means, it is possible to shorten the generation time of image data to be output to the output device, and to reduce the generation time of image data due to unnecessary dot insertion and missing dots. This makes it possible to prevent data quality from deteriorating.

In addition, if dot density conversion is selected by the density conversion selection means, the image data can be output to the output device in a normal character size by converting the dot density to match the dot density of the output device. However, this can be easily made possible by the user's selection.

Send directly to FAX without converting to a dot density that matches the dot density of X.

As a result, when sending a document with a paper size of A4 or smaller to a FAX that can only receive A4-sized image data, it is possible to send a document with a paper size of A4 or smaller to a FAX that can only receive A4-sized image data. This has the effect of reducing the amount of image data to be transmitted, shortening the time for transmitting image data, and reducing line connection charges.

In addition, in this embodiment, a fax machine that can only receive A4 size image data has an A3 size. If you send a B4 size document without reducing it to A4 size image data, it will not be possible to send it due to a paper size mismatch, but by obtaining information on the receivable paper size of the destination fax in advance,
．． If you select paper size conversion to reduce a B4 size document to A4 size, "Dot density conversion specification flag" will be set.
Even if "Do not convert dot density" is specified, A3. This has the effect of easily transmitting a B4 size document to a FAX that can only receive A4 size image data.

〔Effect of the invention〕

When the density conversion selection means selects not to perform dot density conversion, the generation time of image data to be output to the output device is shortened and dot insertion is performed.

This has the effect of preventing quality deterioration of image data due to missing dots.

If the density conversion selection means selects to perform dot density conversion, the user can easily output the image data to the output device in a normal character size.
