Is there a way to request the camera to restrict the size of pictures taken? My project needs two small pictures that would be displayed or printed in a "thumbnail" size, approximately 200x200 pixels. A 6mb picture is way too big for this use. I thought about limiting the file size in the component, but I don't think that would force the camera to downsize the photo.

Thanks!

edit: For future people, this is what I ended up with in the `onFileReceived` event to solve my issue. Forgive my dirty code.

```python
def runAction(self, event):
	from io import BytesIO
	from java.io import ByteArrayInputStream
	from java.io import ByteArrayOutputStream
	from javax.imageio import ImageIO
	from java.awt import Image
	from java.awt.image import BufferedImage
	
	pic_data = event.file.getBytes()
	stream = ByteArrayInputStream(pic_data)
	original_image = ImageIO.read(stream)
	
#	set target size and preserve aspect ratio
	target_width = 640
	original_width = original_image.getWidth(None)
	original_height = original_image.getHeight(None)
	ratio = float(original_height) / float(original_width)
	target_height = int(target_width * ratio)

#	rescale
	scaled = original_image.getScaledInstance(target_width, target_height, Image.SCALE_SMOOTH)
	
#	buffer image for writing
	buffered = BufferedImage(target_width, target_height, BufferedImage.TYPE_INT_RGB)
	g = buffered.createGraphics()
	g.drawImage(scaled, 0, 0, None)
	g.dispose()
	
#	encode to JPEG
	out = ByteArrayOutputStream()
	ImageIO.write(buffered, 'jpg', out)
	out.flush()
	rescaled_data = out.toByteArray()
	out.close()

```

this takes a 7mb image from an ipad and shrinks the file size to 27k

No, but you could use java's ImageIO to decipher the file and then rescale it on the gateway before you store it.

Thank you!

I updated my original post with the code I used to accomplish this. There's probably a cleaner way to do it. Thanks again for pointing me in the right direction.

Yes, your code should be a function in a project library script, so you can do your imports _outside_ the function, along with constants like `target_width`. The actual `runAction` event script should be a one-liner delegating to the project library function.
