Saving as PNG and setting color at the same time doesnt work

[bjornblomqvist]

Do you think you could do a pull request with a fix ?

Sure, shall I just remove the greyscale color mode or shall i check, if there is a color, then it's color, otherwise its greyscale?

[bjornblomqvist]

I think a check would be the nicer option. Then the result wont change for does not setting the color =)

@lichtamberg do still wish do this fix?

Such code doesnt work with this PR.

png = qrcode.as_png(
resize_gte_to: false,
resize_exactly_to: false,
fill: '#FAFAFA',
color: '#f43c12',
size: 300,
border_modules: 4,
module_px_size: 6,
file: tmp_file.path # path to write
)

Colors dont work.

Hi all, I'm generating a QR code and - later - overlaying a color logo on it with mini_magick. The png returned by as_png is a greyscale image even if I set color_mode: ChunkyPNG::COLOR_TRUECOLOR, so the resulting image after I overlay my logo is greyscale. The hack I've found is to also set a foreground color, e.g. color: #111112, but this is counter intuitive. I think that the color_mode option, when set to ChunkyPNG::COLOR_TRUECOLOR, should always return a PNG with the colorspace set to color, even if the QR code is black. What do you think?
