通过ImageMagick添加文本后靠近字体的噪音

Question

我将文字放在图像上并有一些噪音。我该怎么办呢？ 图像magick选项：

[
                currentImage,
                "-font", "Micra-Bold",
                "-pointsize", "40",
                "-strokewidth", "1",
                "-stroke", "black",
                "-fill", "white",
                "-gravity", "North",
                "-annotate", "+0+10", req.body.memData.actNumber,
                "-gravity", "South",
                "-pointsize", "26",
                "-annotate", "+0+10", req.body.memData.actText,
                ""+memsPath+tempName+".jpg"
            ];

Answer 1

噪音可能是JPEG伪影。尝试使用更高的质量（根据＆＃34，您的图像质量为70;识别-verbose＆＃34;）。所以，试试

"-quality", "92",

例如。
