    Format Picture
AI Thread Summary
The user is experiencing issues with the u.are.u 4000 fingerprint sensor when integrating it with a VB.NET application via USB. The expected output is a BMP image with specific dimensions (500x550 pixels) and a resolution of 700 DPI. However, the actual output is a PNG image with reduced dimensions (105x137 pixels) and a resolution of only 96 DPI. The provided sample code from the vendor assigns a random integer value to the "SamplePicture" variable, which does not yield the desired image format. A suggested solution is to use Jasc Paint Shop Pro to convert the image format by opening the file and using the "save as" feature to select the correct format. Further assistance is sought to retain the original image format from the fingerprint sensor.

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
 

Thread 'Is AI hype?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...

Thread 'MS 365 Profile Badge colour'

Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
