ppm2dp is a software that converts image formats for the Deskplayer engine, which is no longer in use. It is a tool designed to help users to easily convert their image files to a format that is compatible with Deskplayer.
The ppm2smap tool, created by A. Schiffler in 1999, is a key component of ppm2dp. It allows users to quickly and easily convert files by inputting the source and destination filenames.
On the other hand, users looking to concatenate .smap files onto .dp files can make use of smap2dp. This tool, also created by A. Schiffler in 1999, offers a range of options to customize the conversion process.
Users can specify input and output filenames, version numbers, and even add delays to their conversions. They can also include URLs for added customization, though this is optional.
Overall, both ppm2smap and smap2dp offer powerful tools for image format conversion and file concatenation. If you're in need of these features, they're definitely worth a closer look.
