Hi,
thanks for reply, i am using this code snippet to save files on SD Card but
the image size is to much e.g above 100 kb . but i want to reduce this size to
1kb, is it possible and if it is possible then what i change in my code.
basically i want to combine these images and make a video with these images.
thanks in advance
camera.setPreviewCallback(new PreviewCallback() { // <10>
// Called for each frame previewed
public void onPreviewFrame(byte[] data, Camera camera) { // <11>
Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();
//YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format == ImageFormat.YUY2 ||
format == ImageFormat.NV16*/)
{
int w = parameters.getPreviewSize().width;
int h = parameters.getPreviewSize().height;
// Get the YuV image
YuvImage yuv_image = new YuvImage(data, format, w, h, null);
// Convert YuV to Jpeg
Rect rect = new Rect(0, 0, w, h);
ByteArrayOutputStream output_stream = new
ByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 100, output_stream);
byte[] byt=output_stream.toByteArray();
FileOutputStream outStream = null;
try {
outStream = new FileOutputStream(String.format(
"/sdcard/%d.jpg", System.currentTimeMillis()));
outStream.write(byt);
outStream.close();
Log.d(TAG, "onPreviewFrame - wrote bytes: "
+ data.length);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
}
Preview.this.invalidate();
}
}
});
thanks and regards
umer

Camera onpreviewframe???
take the picture, then transform it to the required size and save as jpeg with
the appropriate level of compression. What have you tried?
