炒冷饭啦！一键制作Grub背景XPM并压缩成gz文件的方法工具！（2011.1.14更新）
GRUB背景图片的制作方法一：
1、把图片调整为640×480，颜色数为14色，另存为BMP；（i_view32）
2、转换为XPM格式图片；（XnView打开后直接另存为）
3、把XPM压缩成GZ格式；（Gzip）
方法二：
1、用XnView（1.74及以上版本）打开图片，调整大小640×480，转为16色索引颜色,编辑颜色表，修改两组相近颜色，让颜色数为14,另存为XPM文件；
2、用Gzip压缩XPM文件为GZ文件；
方法三：
1、Photoshop打开图像，调整大小640×480，图像→模式→索引：“强制”为无，“透明度”取消，颜色多的图像可修改颜色数为14；检测：模式转回RGB，再转成索引时看到颜色数。
2、保存为BMP后，用XnView+ 1.74版转换为XPM文件。
3、用Gzip压缩成.gz压缩包。
方法四：（已做成批处理，EZ！）
1、用convert.exe直接把JPG文件转换成640×480的XPM文件，参数convert <JPG文件名> -colors 14 -geometry 640x480 <XPM文件名>
2、压缩成GZ格式。
附加说明：
1、XnView+、IrfanView可方便看XPM图像及它的属性，显示为索引8位（256色）是正常的。
2、Gzip是命令行工具，用法：gzip -9 XXXX.xpm
用到的工具如下：（推荐用方法四制作，极傻瓜，只需把JPG文件放入同一文件夹，运行 转换压缩.cmd 即可得到gz文件。
2010.12.22更新：一键制作800×600的XPM。
2011.1.14更新：针对是不4：3比例的图像也能制作出640×480/800×600的XPM
640×480/800×600都包含了：
[ 本帖最后由 古豆 于 2011-1-14 17:55 编辑 ] 方法四已经制作成批处理，解压后把喜欢的JPG文件放同一文件夹，运行“转换压缩.cmd”就OK！
直接得到.gz文件，查看的话先解压再用IrfanView或XnView打开。

http://bbs.wuyou.net/forum.php?mod=viewthread&tid=180028 看过了！收获比较大的！ 方法四确实很方便！谢谢楼主，收藏了！ 感谢分享~..... 還真是方便的小工具。感謝 做的很不错支持了 留个名，参考下
字数补丁 谢谢分享 都是好东西
我也是刚刚开始研究GRUB4DOS，谢谢你给的指导！
今天需要用到，所以到处找，没有更好的办法。谢谢你的方发了。 按照方法四座，XPM文件大小640*480的转换后显示的是640*400,800*600的做成的XPM为800*600，是否正常？ 原帖由 2010waitopen 于 2011-1-9 20:55 发表 http://bbs.wuyou.net/images/common/back.gif按照方法四座，XPM文件大小640*480的转换后显示的是640*400,800*600的做成的XPM为800*600，是否正常？
因为那个convert.exe的参数众多，我英文超烂，无法找到强制按设置比例拉伸图像的参数，所以请先用ACDSEE、PS等把不是4：3的图调整大小，最好直接做成800×600的JPG再转换
上述结果有点迷惑，看640×400好像是原图比例不是4：3，后来的800×600……怎么来的呢？呵呵 convert.exe的参数如下，有英文好的找找哪个是强制分辨率大小的……

'-' for standard input or output. 与其支持800X600图片倒不如支持32色图，要知道，32色与16色相差很远啦。 太好了，支持啊！！！！ 刚好想到要制作，一看论坛，上面就有楼主发的神帖！！！再顶一个！！！ 这个一定要学学，留个脚印 谢谢分享，好东西啊 谢谢楼主分享怎么用XNVIEW修改XPM文件楼主做好的XPM怎么制作呢谢谢QQ357916336
