    Image quality loss

    Hello,

    We're using the ImageProcessor in a new website in below versions:

    • ImageProcessor: 2.6.0
    • ImageProcessor.Web: 4.8.7
    • ImageProcessor.Web.Config: 2.3.1

    When applying ImageProcessor parameters it automatically reducing image quality. We have jpg image with 1920x950px dimensions and if I only add width parameter with the same value (1920px) which is not changing the size of the image, the quality is dropped.

    Here are the example of what I was saying previously:

    Thanks.

    [EDITED]

    We couldn't find out why this is happening. If we uploaded the same image in Black and White and with red filter, only the second one quality was downgraded.

    Black and white Red filter

    As a workaround we just switch to PNG that were after crop at ~500 KB.

    I might be wrong but it looks like ImageProcessor users have previously encountered this issue:
