无法使用 Imagemagick 绘图（没有定义图像）？

2024-8-19 • tag-icon

我见过无法将 PDF 转换为图像，因为“未定义图像”错误- 但这似乎与 PDF 特别相关。

在这里，我尝试做其他事情 - 只是使用在https://imagemagick.org/Usage/draw/#circles；我在bashWindows 10 上的 MSYS2 shell 中：

奇怪的是，如果我通过创建一个空文件touch circle01.png，Imagemagick 会尝试打开它并失败 - 即使我希望 Imagemagick产生这个文件？

如何让它工作？

答案1

呃，似乎我忘了xc:在命令中包含；所以正确的命令是：

magick convert -size 300x300 xc: -stroke SeaGreen -fill PaleGreen -strokewidth 2 -draw 'translate 50,30 circle 0,0 25,0' circle01.png

...这个可以正常生成文件。
