Barcode1DReaderDoScan does not find all barcodes
monster Hi, I'm trying to read the barcode of PDF documents. Most of them are read perfectly, but there's one particular barcode that doesn't seem to work. It has the following syntax: IR-[99999999]-[9999]-QESH-V4. Every PDF with a barcode of that syntax fails to be read. Other barcodes look like th...

Rotate by barcode angle
Hi My application scans documents that contain barcodes. Some documents are scanned skewed and I want to straighten them by the barcode angle. I do something like this: .RotateAngle(intImageId, 360 - CSng(.Barcode1DReaderGetBarcodeSkewAngle(bcIndex))) The rotation works but it's not straightened eno...

Re: Last thumbnail not displayed
My god, I really didn't know that. I should know it! In almost every language you have to declare the type of the counter. How stupid and shameful. Isn't it something "option explicit" should catch? No excuse though...

Re: Last thumbnail not displayed
Oke, I'm pretty sure it's in the GdPicture framework. I've created a new project, added the reference, and wrote this: Imports GdPicture Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load For i = 0 To 10 '<-- Here Next End Sub En...

Re: Last thumbnail not displayed
Hey I always forget to mention the version. At that moment I was using 7.4.03, but I already downloaded revision 10. I can't say the problem is solved in the new release 'cause I get an other error: 'i' is not accessible in this context because it is 'Friend'. For every For-loop that uses 'i' or 'j'...

Last thumbnail not displayed
Hey My thumbnail viewer won't display the last thumbnail, only the text. Screenshot: http://users.telenet.be/lekkere_stud/thumbnail.jpg The thumbnails are loaded with this method: Private Sub LoadAllPDFPages() Dim intIndex As String = 0 Dim intSelectedIndex As String = 0 Dim strFileNoPage As String ...

Re: Anti-aliasing
Thanks, will try it as soon as I fixed an other problem. Since I started using 7.4.0.2 (yesterday), I can't load PDF files anymore. VS tells me he can't find "GdPicture.NET.pdf.gdpdfplug" and that I should put it in the Debug folder. Although it was never nessecary in the past, I've put th...

Re: Anti-aliasing
This is not the only code, but all image manipulation methods are included. Hopefully this helps. With pictureImaging .TwainSelectSource(Me.Handle) If .TwainOpenDefaultSource(Me.Handle) Then .TwainSetHideUI(True) .TwainSetAutoFeed(True) .TwainSetAutoScan(True) .TwainSetPixelType(TwainPixelType.TWPT_...

Anti-aliasing
I've been scanning papers in black and white for a few days now and three days ago suddenly some sort of anti-aliasing is added. I've attached two files which illustrate my problem. I want the quality back to black and white and not the grayscale. I can't remember editing some code which causes this...

GetPixelByteArray
Could it be that the returned byte array is not properly formatted? I get an ArgumentException in the following code: ... ReDim pixels(SquareHeight * tsImageWidth * 4) pictureImaging.GetPixelArrayByte(timesheetImage, pixels, 0, topLeftYCor + ((rowNr - 1) * SquareHeight), tsImageWidth, SquareHeight) ...

Re: TwainAcquireToGdPictureImage Hanging
I was wondering, are you guys still busy fixing this issue? I've opened a ticket on your support site as you asked but it keeps sending me emails saying I didn't reply on suggestions and the ticket will be closed. As you can see in the ticket's conversation history, I did reply, so the site had no r...

Method to analyze pixels
Hey there Is there a way to count the number of black pixels in an area? For example: In a 400 X 300 B/W image, I would like to count the number of black pixels in an area that's 15 by 15 pixels and in the bottom right corner. Is this possible? I have been looking in the Pixel Access methods but fou...
