暂时没有的 我最近有点事缠身 没弄 打断了学习节奏 哎。。你搞定没有。。o(╯□╰)o

网上找到了

交作业了。part4太繁琐，暂时先toPixImage,再压缩一遍，解决了setPixel()方法。

1. java PixImage

终于搞定了，开心～继续努力～早日刷完～

恩恩（我也搞定了）！继续刷  最近节奏总是被打断 伐开心
抓紧时间了~

终于把4个部分都做完了，花了四天时间，看到autograder打分为19/19还是蛮激动的。做的是2014年版。

同学，哪里可以访问autograder啊？

跑一下目录下面那个Test.java就行了

谢谢啦，找到了

各位好， 我运行test.java 显示
java.util.zip.ZipException: Not in GZIP format
        at java.util.zip.GZIPInputStream.readHeader(GZIPInputStream.java:165)
        at java.util.zip.GZIPInputStream.<init>(GZIPInputStream.java:79)

        at Test.main(Test.java:846)
Beginning Part I.
Performing 5 boxBlur(1) calls, then one boxBlur(3) calls on a 11x15 image.

        at Test.main(Test.java:853)
Exception in thread "main" java.lang.NullPointerException
        at Test.main(Test.java:861)
请问这是啥情况。。。

求问part1的PicImage.java编译完了没有出错，然后是运行Blur和Sobel就会出来图片吗？？
已经按照前面楼上说的将两个.jar导入classpath了，用的是eclipse...可是接下来在哪里看处理好的图片呢？？
感激不尽。

摸索了好久无果。。。先把代码运行成功的截图放上来。
