PPM Format Image Conversion

The built-in logomaker used to logo the mini2440 Development Board. It can be used normally under fedroa. Now it is replaced by ubuntu9.10. First, there is no netpbm package. After using apt-Get install netpbm, logomaker does not prompt an error, but always generates a 0-byte image.

In fact, after installing netpbm, there will be a series of tools that can be used for direct conversion. logomaker is also calling these tools.

 

The conversion method is as follows:

You can use the topnm tools for BMP images, such as BMP toppm.jpg, PNG, and GIF.

$ BMP toppm pic.bmp> temp1.ppm // generate ppm

$ Ppmquant 224 temp1.ppm> temp2.ppm // convert to 224 color

$ Pnmnoraw temp2.ppm> logo. ppm // convert to ASCII format

 

Logo. ppm is the desired image.
