PTX Texture Converter

Overview

PTX Texture Converter is a command line tool to convert images stored in different file formats (JPG/PNG/DDS/etc.) to PTX texture format. The format has been designed so that the files can be loaded to memory as binary blob without need for post-load processing, which enables storing the textures to flash memory on microcontrollers. Currently the tool supports various RGBA formats, but only 2D textures and no mipmaps. You can find the Windows executable of the tool in bin directory and by running ptx_conv.exe -h. you'll see the different options. For example running

ptx_conv.exe -i smiley.png -o ptx_smiley.h -hexd -f r5g6b5

Converts the smiley.png image in the dir to ptx_smiley.h file with pixel format r5g6b5, which can be #included in Arduino programs to be embedded in the executable and stored in the flash memory.

Compilation Instructions

1. PTX Texture Converter depends on mini_sxp core library, so first you need to clone the library (or copy the zip) to some directory.
2. Run install.bat and type in the directory where you cloned the library (i.e. where mini_sxp README.md file resides). This creates the appropriate symlink to the directory.

Now you should be able to open ptx_conv.sln in Visual Studio and compile the tool. If the created symlink doesn't work, Visual Studio will fail to load mini_sxp library.
