TWAIN Capture

Top  Previous  Next


A common source of images is an external device, such as a scanner or digital camera. Most manufacturers provide a TWAIN interface to transfer images from the device to the application.


With CodedColor, you can use this interface for importing images in one of three ways:


Single page

Use this option, if you want to import/scan one image and open it directly in the Editor window.


Multiple pages

If you have several scans to do and want to save some time.


Multiple pages to TIFF

Use this option, if you want to create a multipage image (TIFF or GIF file) from multiple input sources or documents.

To acquire further frames after the first document page is scanned, click on TWAIN: Add Frame in the toolbar of the Image Editor.


Multiple camera files to disk

Use this option if you want to acquire multiple images, each into a seperate file. Recommended for digital cameras.

With this option you can also set the Output format and folder. If you choose JPG as your destination format, set a compression of about 96 (More options) to achive the best compromise between filesize and quality.


To import images from your device, follow these steps:


1.Connect your scanner or camera to your computer and turn it on.


2.Call File > TWAIN Image Capture.


3.If you do not see your device in the Select device dropdown list, first check all cable connections to your device. If you have an SCSI device, then most likely Windows has not yet detected that you turned it on. To force this, click on Detect SCSI Device, activate the Hardware tab and start the Device manager. Select SCSI Controllers, and select Search for changed hardware from the right mouse menu. You may need to restart the TWAIN capture dialog of CodedColor after this.


4.        Enable the checkbox Device dialog visible, to open the user interface of the TWAIN driver.


5.Disable buffered transfer, if you experience problems acquiring the image.


6.For Single and Multiple pages, you can rotate or resize the acquired bitmap in the image editor, choose Save As and store the image in the desired format. For text documents or graphs, you should use the GIF format. An image with multiple frames (pages) must be saved as TIFF. For single photos, JPEG usually produces the best result (size vs. quality)

If your TWAIN input device is a digital camera, you most likely have access to your photos via drive letter in the Windows Explorer or through a memory card reader. You should then always copy the files manually to your local hard drive. An external software like CodedColor, which uses the TWAIN driver of the camera to import the files, will always transfer your photos as bitmaps, which would naturally result in a loss of all EXIF/IPTC information.


After you store the files to disk, you can do further batch processing, like SmartFix, Noise Removal and Rotation. Only do left/right rotations on the stored JPG files, because then the rotation will be lossless and you won't produce artefacts.
