AVT cameras - Marlin, frame grabbing
May 3rd, 2009, 1:29pm  
I'm using a Marlin Allied webcam on a Mac OSX 10.5.
There was a problem of resize:
I wanted to use a image of 320x240 > the image grabbed was minimum 640x480.
Due to the cropping system of Capture.class, i got only the middle of the frame.

After several hours of research in Capture, i came to this point:
If i declare a Capture of 640x480, i get the full frame.
I just changed the crop function in read(): instead of cropping, resizing the image >>

PImage temp = new PImage(dataWidth, dataHeight);
raw.copyToArray(0, temp.pixels, 0, dataWidth * dataHeight);

PImage resized = new PImage(requestWidth, requestHeight);
resized.blend(temp, 0, 0, dataWidth, dataHeight, 0, 0,
requestWidth, requestHeight, PImage.BLEND);
pixels = resized.pixels;

Any better idea to fix this?
