China DOS Union

Regarding creating a GRUB background image, I saw a netizen mention:

In Linux, just one command does it
convert -resize 640x480 -colors 14 orgname.jpg bootimg.xpm

Actually, there is a Windows version of convert, see the attachment.

Under Windows, the usage is:
Extract the convert tool from the attachment to any directory, enter the directory where convert is located in the command line, and then enter the command in the following format to complete the conversion in one go:
convert abc.jpg -colors 14 -geometry 640x480! abc.xpm
After conversion, you can compress it into gz format using gzip or wingzip.


Original and effect images in xpm format:

Is no one wanting this thing?

Actually, this convert is from ImageMagick. I installed many different versions of ImageMagick for testing and then extracted this green and usable convert.

I saw on the ImageMagick Chinese website that there are: 16-bit pixel Windows installer (including DLL), 8-bit pixel Windows installer (including DLL), 16-bit pixel Windows installer, 8-bit pixel Windows installer and Linux and other different versions. The attachment is extracted from the "8-bit pixel version".

Thanks for sharing

Thank you so much.. really good stuff. Push it up for everyone to share

Thanks for the楼主's share...

Just used. After conversion, the quality is too poor. Still, converting with XNVIEW to a gray-scale 16-level dither effect is the best. The effect of color images after conversion by any software will not be ideal. Only the gray-scale + dither effect is the best.

No matter what software is used to convert color images, the effect will not be ideal. Only the effect of gray scale + dither is the best.

The 14-color color really isn't very good. Just as you said, "No matter what software is used to convert color images, the effect will not be ideal." The effects converted by other software are also like this, and even not as good as this effect. But after using it, I feel that this is still relatively convenient.

Hehe, although I have already downloaded it on Wuyou, I still help to top it. Thanks to the landlord for sharing!

Received one, thanks for sharing~~~~~~~~~~~~~~

Thanks for sharing

Just what I needed. Thanks to the LZ

Not bad, simple and practical.

Heheh, adjust the order of the commands under win with reference to the commands in the linux environment:
convert -geometry 640x480 -colors 14 abc.jpg abc.xpm
Then you will get an effect that is really different.

Of course, it's not impossible to directly use the linux commands under win
convert -resize 640x480 -colors 14 orgname.jpg bootimg.xpm
