Qualiy Loss + Noise with GD IMG resize

[ocr_a]

Hello,

i work a lot with graphical images with type, full backgrounds and sometimes images, not photographies, so its hard to choose between jpg and png. i also need to resize my images for different device widths.

so here is what occured:

• resizing the image causes the grey and white backgrounds to get some »render glitchy« noise. jpg files have more a stripe type, while png have more a noisy type.

• i checked imageconvolution and imagequalities -> its always there, no matter what options i chose.

• i checked imagick -> imagick is better at this

so my question is:

is there a way to improve the gd resize functions?

is this a known issue? - i been searching for this alot, but didn't find a clear answer.

thanks!
