Fingerprint does not recognize its own image with IBM Datacap Taskmaster Capture

Fingerprint does not recognize its own image with IBM Datacap Taskmaster Capture

After creating a new fingerprint using Datacap Studio, the same image is run through a batch and recognition fails to match the image to the fingerprint.

Cause

When adding a fingerprint in Datacap Studio, the FingerprintAdd ruleset is used. If the actions in this ruleset do not match the actions affecting recognition in the application, then recognition will fail.

Resolving the problem

Edit the function in the FingerprintAdd ruleset and add any actions used by the application that would modify the image or the behavior of the RecognizePageOCR_S action.

VScan aborts after changing the batches directory path with IBM Datacap Taskmaster Capture

VScan aborts after changing the batches directory path with IBM Datacap Taskmaster Capture

VScan aborts in Taskmaster Client or Taskmaster Client Service after changing the batches directory path in Taskmaster Application Manager.

Cause

When using Taskmaster Client or Taskmaster Client Service, any change to the file path of the batches folder must be followed by going to Task Settings and resaving the task in order to propagate the setting from the application file to the admin database.

Environment

This is applicable only to Taskmaster Client and Taskmaster Client Service, not any other clients to include Taskmaster Web.

Resolving the problem

After changing the batches directory path, do the following:

1. Open Taskmaster Client


2. Go to Settings -> Workflow


3. Expand the corresponding workflow


4. Locate and select the batch creation task


5. Click the Setup button


6. Go to File -> Task Settings and then press OK on Settings for VScan task


7. Click Done on the VScan Setup - Batch Pilot window


8. Click Apply on workflow window, then click Done

If there are multiple jobs, the steps do not need to be repeated for each scan task unless a different scan module is used.

How do you increase RV2 MaxResultReports records using IBM Datacap Taskmaster

How do you increase RV2 MaxResultReports records using IBM Datacap Taskmaster

The RV2 MaxResultReports limit is 5000 records,To increase it in IBM Datacap Taskmaster Capture We have to do the fallowing Modifications.

Open the C:\Datacap\RV2\web.config file, search for the MaxResultsReports key, and modify the value. The request goes through Taskmaster Server which has a hardware based limit around 10,000 records for a typical work station. Clients will appear to freeze up when the limit is reached.

Optimizing barcode recognition with IBM Datacap Taskmaster Capture

Optimizing bar code recognition with IBM Datacap Taskmaster Capture

During printing, the ink can bleed or spread out over the white area, and then, during scanning, additional spreading of black may occur. As a result, the white spaces end up disappearing and the bars blend into each other. This can be seen by looking at the scanned image at high magnification. The barcode must meet the specifications after accounting for this.

To optimize barcode recognition:

• The width of the thinnest bar (called the X-dimension) must be at least one pixel, and two pixels are recommended for best results. At 200 DPI this means each bar must be at least .01 inch. Generally this translates to about 4 to 5 characters per inch.


• The X-dimension or width of the narrowest black bar and white space between bars must be at least 20 mils (1/50 inch, 1/2 mm). When scanned perfectly at 200 DPI this would result in 4 pixels, and at 300 DPI 6 pixels.


• For Code 39 symbols: a 20 mil X-dimension results in a density of approx 3.6 characters per inch. Optimally the height should be at least 1/4 inch or 15% of the width, whichever is greater, though this is not an absolute requirement. The minimum quiet zone (white space before and after the bar code) specified by the standard is 1/5 inch.

Scanning can sometimes introduce white or black stripes on the image running in the scanning direction, typically vertical stripes if the paper is scanned in Portrait orientation. Bar codes printed in normal horizontal orientation cannot be read reliably when this occurs. It is advisable to print barcodes perpendicular to the direction of scanning. If the barcode must be printed horizontally on a page, scanning in landscape orientation will make the barcode more robust in the presence of common scanner issues.

VScan Tips

In Data cap taskmaster application ,when we are giving input from the shared folder/local drive we have to check the size(Number of Images) that we are giving as input.If number of images are high(i.e more than 500...etc)the system will take more time to import them into the current batch..

Because the data cap internally sorting the input images and then it is assigning the name.For Example if we are giving the 10,000 images as input at a time,then it takes 6-8 minutes to take all images in to memory and to sort.in many cases the system will not respond for 5-6 minutes.

So,the better method is, dump limited number of images by using the scheduler.

Note: This is the case where the number of input images are high,Not in the case of input images size are high.

Datacap Export Pre-Requisits

Hi all,

As we are all aware,the Datacap Supports the Exporting the indexed values to the many types of databases.Datacap mainly supports the fallowing things.

1.Any file type.(for this we have to use the action SetExtensionName(".dat")    from Export Action library.s

2.Datacap supports the databases like Oracle,SQL,Ms-Access...(For this we have to use the ExportDB action Library

3.Datacap also supports the Repositories like FilenetIDM,FilenetP8, IBMCM, LiveLink, SharePoint....

4.We can also export to the SAP using the Web-services. for this we have to use our own custom actions.

 

Note:*

1.  Datacap Required the Repositories client(i.e FEM client,SAP Client...) in the Task master server  mechine.

2.For Databases we need the Providers.

 

 

ERROR:Unable to select image in Batch Pilot Properties Window using IBM Datacap Taskmaster Capture

Unable to select image in Batch Pilot Properties Window using IBM Datacap Taskmaster Capture

When we attempting to specify an image, by using the Picture property in the Property window for a Batch Pilot control, the selection reverts back to none.

This is due to The Picture property is no longer supported in Batch Pilot and code must be used to add an image to a form.

To set a picture to an image control:

1. Run Batch Pilot.


2. Open the project and bring up the Verify DCF or whichever form the image will be added to.


3. Double click anywhere in an empty area of the form.


4. In the first drop down select Pilot and in the second drop down select FormRun.


5. After the Dim section put a line as follows, where Image1 is the name of the control.
   Image1.Picture = LoadPicture("C:\Datacap\APT\Graphics\fprintnew.bmp")
