What kind of tools does convert -quality use in command line?

[turkdue]

Hello,

I am doing a project where I use convert -quality <value> in order to decrease the quality of a jpg image. I was wondering if the IJG quality standards and the related libjpeg quantization tables are used for this? I have been looking at the GitHub Repo to see if there was any reference, however, I am having trouble finding it. I need to find a source that suggests it. If anyone knows where I can find it, it will be very helpful.

Thanks.

Have you looked in coders\jpeg.c?

Is that applicable for the command line convert -quality value option?

Yes.
