model中我定义了一个测试的方法test_mini。用来处理参数pic_path传递过来的图片。
def test_mini(pic_path)
pic=MiniMagick::Image.new(pic_path)
#pic.border(200)
pic.font 'helvetica'
pic.draw 'text 100,100 "gogogogogogo"'
#pic.draw "image SrcOver 0,0 0,0 123.jpg"
end
出现了问题，如果我把最后pic.draw "image SrcOver 0,0 0,0 123.jpg"这句注释掉，那么这段代码是可以执行的，能够在上面写字。
但是我不注释掉这句在上面加水印的句子，就会出现错误。请问有没有人能帮到我？

[b]问题补充：[/b]
我又测试了一下,除了draw,还有一些命令是同样出现这个问题的.
所以我也很奇怪.
如果是插件的问题,但是有些命令是可以实现的.
而同样的格式有人测试是可行的.也应该不是引用语法的错误.
那么问题出在哪呢?我google了一下,有人说是获取文件路径的问题.我觉得这个嫌疑也最大,但是我按照他的做法,加入了app的路径之后还是不行.很无奈
不知道大家有没有其他的一些配置要注意的地方我可能忽略了的?或者经验能分享一下呢?

我的本地有123.jpg.......
你改一下你本地的123.jpg的文件，换成 不是数字开头的
然后，draw的命令也换
因为，单纯找不到文件，应该提示No such file or directory.
不是mogrify: Non-conforming drawing primitive definition `image'

我只能怀疑，你打错了什么东西，上面那个是我自己打的，下面那个是直接拷贝你的。你拷贝我的命令试试看？

又或者只有文件名123.jpg不行？auto.jpg是我文件夹下存在的图片
不是格式的问题，是文件名，你看我第二次贴的记录
auto.jpg是我本地有的文件，可以正常执行
auto2.jpg和123.jpg和123auto2.jpg是我们本地没有的文件
只有以数字开头的文件提示
[code="java"]mogrify: Non-conforming drawing primitive definition `image'[/code]
不是数字开头都是提示
[code="java"]irb(main):025:0> pic.draw 'image SrcOver 0,0 0,0 auto2.jpg'
mogrify: unable to open image `auto2.jpg': No such file or directory. [/code]
