Hi guys,

I captured the screenshot of device. This is like a bitmap object. I need to convert from this bitmap object to bitmap image. Is it possible in Blackberry?

Please help me out through this.

Thanks in advance,

What program did you use to capture the screenshot? Is the file on your PC or on the device? What is the file name and extension?

I used this code to capture the screen shot.

Bitmap bitmap = new Bitmap(width, height);
Display.screenshot(bitmap);

After taking the screenshot I can convert from bitmap object(screen captured data) to ".JPG" and ".PNG" image formate also using this JPEGEncodedImage.encode(bitmap)

But BMPEncodedImage doesn't have encode method so i am using

byte[] _bytes = getBytesFromBitmap(bitmap);

BMPEncodedImage.createEncodedImage(_bytes ,0,_bytes .length);

while am using this method its throws "IllegalArgumentException".
Then using Fileconnection to save the image in device memory.

public byte[] getBytesFromBitmap(Bitmap bmp) {
try {
int height=bmp.getHeight();
int width=bmp.getWidth();
int[] rgbdata = new int[width*height];
ByteArrayOutputStream bos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(bos);
Graphics g = new Graphics(bmp);
bmp.getARGB(rgbdata,0,width,0,0,width,height);
for (int i = 0; i < rgbdata.length ; i++) {
if (rgbdata[i] != -1) {
dos.writeInt(i);
dos.flush();
//l++;
}
}
bos.flush();
return bos.toByteArray();
}
catch (Exception ex) {
Dialog.alert("getBytesFromBitmap: " + ex.toString());
return null;
}
}

I need to know whether Blackberry supports saving the captured image into raw BMP format.
Also, can we directly capture images into a specified format like 1bit, 4bit mono, 4bit color, 8bit, 16bit etc)..

Sorry, I don't know code. There are a few apps that will do screenshots on the BlackBerry. I think that would be a lot easier than what you're trying to do.

JL_Cmder is one -- can be found on forum search.

I think there's another one, but I can't remember for sure.

Thanks for your reply Daphne.

It occured to me -- if you are a developer, you should post in the developer's forum here. You might get some help there.
