Hello,
I am using the pi camera HQ, on archlinux arm, and picamera==1.13 and attempting to set JPEG quality during capture.
Adapting the documentation recipe:
import time
import picamera
with picamera.PiCamera() as camera:
camera.resolution = (1024, 768)
camera.start_preview()
# Camera warm-up time
time.sleep(2)
camera.capture('foo.jpg', quality=90)
I notice my images are the same approximate size regardless of what value I set for quality.
Using ImageMagick's identify confirms Quality is actually 100, not 90 as set:
Certain file formats accept additional options which can be specified as keyword arguments. Currently, only the 'jpeg' encoder accepts additional options, which are:
quality - Defines the quality of the JPEG encoder as an integer ranging from 1 to 100. Defaults to 85. Please note that JPEG quality is not a percentage and definitions of quality vary widely.
It seems that the default is actually 100 for this camera/setup?
Does anyone else have the same pproblem or a solution?
