SUMMARY

The discussion centers on the inability to capture images in the desired BMP format using the u.are.u 4000 fingerprint sensor linked to a VB.NET application. The user reports receiving images in PNG format with reduced dimensions and resolution. The sample code provided by the vendor does not yield the expected output, leading to confusion regarding the format of the captured image. A suggested solution is to use Jasc Paint Shop Pro to convert the image format post-capture.

PREREQUISITES
  • Understanding of VB.NET programming
  • Familiarity with image formats, specifically BMP and PNG
  • Knowledge of USB device integration in software applications
  • Basic skills in image editing software like Jasc Paint Shop Pro
NEXT STEPS
  • Research how to manipulate image formats in VB.NET applications
  • Learn about the u.are.u 4000 fingerprint sensor SDK and its capabilities
  • Explore image processing techniques to maintain original image quality
  • Investigate alternative libraries for image handling in VB.NET
USEFUL FOR

This discussion is beneficial for software developers working with biometric devices, particularly those integrating fingerprint sensors into applications, as well as anyone involved in image processing and format conversion.

Help! Its URGENT! I'm using u.are.u 4000 fingerprint sensor to link with my vb.net application via the USB port. I can't get the original format of the picture captured via that device. The original format of the captured picture should be bmp format, 500 width and 550 height, 700 resolution. But, What i get is a png format, 105 width and 137 height with 96 only for resolution.

This is the sample code provided by the vendor in vb:

Private Sub RegSample_RegSample(SamplePicture As stdole.Picture, CurFingerIndex As Integer)
Image1(CurFingerIndex).Picture = SamplePicture
End Sub

I found that value for "SamplePicture" is an integer random number, for example, 671419403, -1475865658 and so on. I'm stuck here. Anyone can help me to get or keep the original format of the captured image?

I really pray to get valuable replies and assistance from anyone who have knowledge about this. Its urgent!...thanks

I would suggest installing a program such as Jasc Paint Shop Pro- this program has the ability to read and change the format of any picture you would just need to open the file then "save as" and you will see how you can scroll through the index of formats all are there good luck
