Short answer: imageBuffer1 is just a pointer. The array is still connected to
the BufferedImage object. So when the function modifies imageBuffer1, it has
the effect of also modifying the parent image.

Leigh, you are the best!
My problem is solved. am really really grateful and also excited. u wont
believe i have spent nights and day on this thing.
But there is a part i dnt understand.

i then passed imageBuffer1 to the function..

Hmm.. if all the function does is populate a supplied byte array, then it

Are you looking at the java documentation/api? It seems odd they would not
provide more detailed information, or at least a few code examples.
I am just guessing here. But that sounds li

Go to the documentation for the fingerprint device, then, to determine what
the file format is. There are a number of formats that browsers can't
handle (not CF, but the browsers themselves), such as progressive JPEG and
CMYK JPEG. If it's one of those, then you may need a 3rd party converter

Thanks, i have actually tried it. i just discovered that the problem isn't
displaying the image. it is most likely that cf does not support the format of
the image in the byte array.
The byte array

Apparently you can also pass in the image bytes directly, without using a
Bufferedimage. ie ImageNew(byteArray)
I cannot believe I never knew that one.

Ray should be right. I've passed raw image byte data from flex to
coldfusionjedi with no problem. If you're receiving the data in a cfc
just type the argument as binary.

Is it a Java buffered image? If so you can pass it to ImageNew(). Have
you tried that?

Please i need display an image from a byte array. The byte array contains a
fingerprint image captured from the fingerprint device. I am using the java
class from coldfusion, i am having problem displaying the image from the byte
array.
The fingerprint device is Secugen Hamster plus should
