Background on imageWithLogo

[oehoe]

Thanks for this great project! I'm using the imageWithLogo example and I end up with a background color '#f5f5f5'. The 'imageTransparent' and 'imageTransparencyBG' QROptions don't seem to work. How do I get these options working?

Hi! I've added a bit of documentation re this in #121 - see this comment for more info. Hope this helps!

Hey, Thank you I read the information. What I got out of it is that the imageTransparencyBG option would set a different background color with imageTransparent false.

In my case the imageTransparent true does not render the image transparent. With transparent false, imageTransparencyBG did not change the background color.

Sorry if I missed the solution in your post.

Ok, i think I've found the culprit. I've added a line to ensure the circular dots are actually round on low scales (scale <= 20) - internally it scales the image up, draws the dots and scales it back to the expected size - all while using the IMG_BICUBIC filter - which is what messes with the background color. So try to set QROptions::$scale to a value greater than 20 or set QROptions::$drawCircularModules to false.
Alternatively i would recommend to use the SVG output for more crisp circles and colors. :)

I've added a bit of info to the corresponding docblock.

Nice! I'm gonna give it a try! Thanks for looking into it.

I set the scale to 25. Works!
