2. TWAIN

2.1. TWAIN

TWAIN is the specification that defines the standard software protocol and application programming interface (API) for data exchange between a software application program and an image input device such as the image scanner.

[TWAIN development background]

In the past, development of a new scanner inevitably required the development of a compatible driver and a sample (demonstration) program exclusively designed for the new scanner. As the scanner is upgraded, the driver may need to be upgraded as well to maintain its compatibility with the upgraded scanner. Therefore, the use is most likely to be restricted to one specific scanner model to avoid the complication of learning new operation methods and replacing the peripheral driver, etc., involved in scanner replacement.

In view of the incompatibility among different scanners and peripheral equipment and the accompanying inconvenience, there was a demand for standardization of the related hardware and software, and TWAIN was established as a result.

The user may now choose among all the input devices and software (driver or application programs) conforming to the TWAIN standard, and configure a most suitable system for himself, without being restricted to the products of a certain series or a certain manufacturer.

2.2. TWAIN Application

TWAIN mainly applies to the following three software components:

 Application software

 Source manager

 Source

The components are related to each other as shown below.

The preview window is used to display the temporary image of read data and for setting the "Scanning Area."

For settings, see "Scanning Area" later in this manual. Also see the description of the [Preview] button later in this manual.

♦ Ruler

The large divisions are labeled as "Unit". The scale also varies with the selected scanner.

♦ Message line

The message line is the bottom line of the dialog in which a brief explanation of an input item or a setting item is displayed when the mouse cursor is moved over the item.

♦ Data size

The approximate amount of data per image when data is scanned in the present option.

Note.

This value is the amount of uncompressed data. The size of the stored file will differ from this value and is usually smaller if image compression is chosen and the image is compressed.

4.4. Setting Information on Image Scanning

♦ Current side

When a scanner that allows duplex scanning is used, specifies the page which sets the image scanning information.

To scan using the same settings as those for "Front side" and "Back side," clear the checks in the "Individual Setting" checkbox on the "Front" and "Back" tabs. A single "Duplex" tab will be displayed at the left so that the same image scanning information can be set for "Front side" and "Back side."

To scan using different settings for "Front side" and "Back side," check the "Individual Setting" checkbox on the "Front" and "Back" tabs. Two tabs, "Front" and "Back," will be displayed at the left. Select each tab and enter the desired settings.

This is only effective when ADF (Duplex) is selected for the method of paper feed. For scanner types which permit duplex scanning, see "Relevant Image Scanner Specification" in the Appendix.

♦ Resolution

Specifies the number of pixels (dots) per inch. Select a predefined resolution or [Custom] from the list. [Customize] enables detailed settings by a pixel unit.

By marking [Predefine] checkbox, you can select one from three predefined settings as [Normal], [Better], [Best] to scan documents instead of configuring settings by yourself.

Otherwise, you can change the details of the predefined settings on the [Resolution Setting] window, which appears when you click on the […] button.

Resolutions for Image modes (“Color”, “Grayscale”, and “Black &White”) of the each predefined settings are changed corresponding to the selection of the Image Type.

* Click [Default] button to return the resolutions to the default value.

High resolution produces finer images, meanwhile requires more memory that leads to longer scanning time.

The supported resolution depends on the type of scanner and the options installed. Refer to "Relevant Image Scanner Specification" in the Appendix.

♦ Paper Size

Specifies a document size for scanning.

Select a standard size or [Custom] size (can be registered up to three) from the list.

Window for customizing the paper size will appear when you click on […] button besides the list. On this window, you can change the order of the paper size in the list.

[Custom] button : Used for configuration of a custom size.

[Up] button : Used for shifting the order of the selected document size upward.

[Down] button : Used for shifting the order of the selected document size downward.

You can register up to three sizes as the customized document sizes.

[Custom Paper Size Setting] window will appear when you click the [Custom] button. Enter the size of the document to be scanned. (When entering the size, specify the paper size by width x length to the scanning direction.)

Some paper sizes may not be accepted by your device. Refer to "Relevant Image Scanner Specification" in Appendix.

Name :

Enter the name of the customized setting to be displayed in the list.

Width, Length

: To specify a custom paper size, use the scroll bar or enter the paper

size directly. The unit specified in [Option]-[Generic]-[Unit/Scaling] will be applied to the unit in this window.

♦ Scanning Area

Specifies the start position, width and length for the image scan. The maximum allowable size is the paper size selected previously.

In addition, the minimum size is 1.000 inch, 26 millimeters, or pixels (number of dots per inch) according to the unit that has been set.

"Left": The left end of the scan area on the scanned document (X coordinate)

"Top": The top end of the scan area or the scanned document (Y coordinate)

"Width": The width of the scan area

"Length": The length of the scan area

These values are related to one another in the following way:

0 ≤ left end coordinate < (paper width - minimum scan area size)

0 ≤ top end coordinate < (paper length - minimum scan area size)

Minimum value ≤ width ≤ (paper width - left end coordinate)

Minimum value ≤ length ≤ (paper length - top end coordinate)

♦ Scan Type

Selects the feeding device. The image scanner uses a document bed called the flat bed as well as an automatic document

feeder (ADF) for feeding scanned document. The ADF usually enables the documents to be scanned only once. The flat bed allows scanning the same documents repeatedly.

Flat bed

Scans a document placed on the flat bed of the device.

ADF (Front Side)

Scans the documents on the device's automatic document feeder (ADF). Here, only the front sides are scanned.

ADF (Duplex)

To scan both the front and the back of a page, select this option. If this option is selected, the documents are scanned in the "front to back to front to

back ..." order. This option can be used only for scanner models that support duplex scanning. The "Duplex Function" requires that the calling application supports "continuous scan."

If the application does not support "continuous scan," only the data for the front side of the page is passed to the application.

Some scanner models do not support this option. See "Relevant Image Scanner Specification" in the Appendix.

Long page (Front Side)

Scans a document longer than the paper size which can be specified by [Paper Size]. In this case, only the front sides of documents are scanned. When this option is selected, the "Paper Size Setting" dialog box opens. Specify the size

of the document to be scanned.

* While the "Long page" is specified, the preview window cannot be displayed and the

scanning area cannot be specified.

* In case of some scanner models, while the "Long page" is specified, color and grayscale

settings can not be selected in [Image mode]. (Refer to “Relevant Image Scanner Specification” in the Appendix.)

* Depending on the scanner, [Resolution] setting should be set to less than 400 dpi.

* The "Long page" is not displayed in the [Scan Type] dropdown list if not supported by the

device. See "Relevant Image Scanner Specification" in the Appendix.

Long page (Duplex)

Scans a document longer than the paper size which can be specified by [Paper Size]. If this option is selected, the documents are scanned in the "front to back to front to

back…" order.

ADF (Back Side)

Scans the documents on the device's automatic document feeder (ADF). Here, only back sides are scanned.

Note.

To specify duplex scanning, the number of copies designated should be based on the number of pages, not the number of paper sheets. In other words, one original with a front and back is regarded as two pages.

♦ Image Mode

Selects an image mode for scanning the image. Select a corresponding image mode from the list.

Black & White

Scans data by using the fixed threshold binary, black-and-white. Distinguishes black from white by the setting in the "Threshold" of "Scanning Parameter". This scanning mode is suitable for scanning line drawings and text documents.

Halftone (Dither)

Scans data using the halftone processing, with dithering or error diffusion. Uses the patterns set in "Halftone" to simulate data in black-and-white. Selection of built-in dithered patterns or error diffusion (not supported by some device models) is allowed. This scanning mode is suitable for scanning images containing light and shadow such as a photograph.

Gray scale

Scans data using 256-level monochrome gray scale. Light and shade in photographs can be represented with greater fidelity. This scanning mode employs far more memory than the Black & White mode. Some versions of the scanner do not support this scanning mode. For details contact the retail store where the device was purchased.

4bit Gray scale

Scans data using 16-level monochrome gray scale. Data size is smaller than "Gray scale" selected. Some versions of the scanner do not support this scanning mode. For details contact the retail store where the device was purchased.

Automatic separation

Scans data distinguishing line drawing from photograph image. If this option is selected, the line drawing part is scanned using "Black & White," and the photograph part is scanned using "Halftone". This information is most suitable for

documents containing both photographs, and line drawings or text. Some scanner models do not support this option. See "Relevant Image Scanner Specification" in the Appendix.

SEE (Selective Edge Emphasis)

Scans data using the halftone processing and emphasizes line drawings and text. This option is most suitable for emphasizing only text of documents containing both photographs and text. Some scanner models do not support this option. See "Relevant Image Scanner Specification" in the Appendix.

24bit Color

Scans data using 24 bits color. This mode is suitable for scanning color photograph and

employs far more memory that Gray scale mode. Only color scanner models support this option. See "Relevant Image Scanner Specification" in the Appendix.

256 Color

Scans data using 256 colors.

Data size is smaller than "24 bit Color" selected. Please note that the image quality of "256 Color (8 bit)" is inferior to the case of "24 bit Color ". Choose "24 bit Color" for higher quality. Only color scanner models support this option. See "Relevant Image Scanner Specification" in the Appendix.

8 Color

Scans data using 8 colors.

Data size is smaller than “256 Color” selected. Please note that the image quality of "8 Color" is inferior to the case of "24 bit Color" and "256 Color (8 bit)". Choose "24 bit Color" for higher quality. Only color scanner models support this option. See "Relevant Image Scanner Specification" in the Appendix.

♦ Black & White

Specifies the processing method when "Black & White" is specified in "Image Mode".

Static Threshold

Executes simple binary processing based on the "Threshold" setting.

SDTC, DTC mode

To enable the auto binary function of the image scanner, specify this option.

If this option is selected, the "Threshold" setting will be disabled.

In addition, auto binary has two modes: " SDTC Mode" and "DTC Mode". These

modes can be set using the "Advance" dialog box.

"DTC Mode", however, is limited to the image processing options. Therefore, only

scanner models that have image processing options support "DTC Mode". See

"Relevant Image Scanner Specification" in the Appendix.

SDTC mode (Floating Slice)

This option enables scanning and fine binary processing for documents whose backgrounds are other than white such as newspapers. Some scanner models do not support this option. See "Image Scanner Specification" in Appendix.

Advanced DTC

Scan in fine binary mode regardless of the document.

Normal binary mode can’t scan very well faintly toned documents, documents with

colored background, or documents with color charts. Choose this to scan these

documents clearly.

♦ Halftone

Select the halftone pattern for halftone scanning from the built- in pattern list. Select the desired halftone pattern for displaying the obtained image. This setting is

effective when "Halftone" or "Automatic Separation" is selected in "Image Mode". Some scanner models do not support this function. See "Relevant Image Scanner

Specification" in Appendix.

Dither Pattern 0

Executes pattern processing that is suitable for scanning a dark photograph.

Dither Pattern 1
