how can you turn a .png into a .txt (for Prime Icon)
I thought that the HP Prime's ICON command was in .png format and i wrote a program. Planning to add an ICON.
However, when I dropped to DOS and renamed file.png to file.txt I typed the file out and it seems to be an unprintable binary file. Not a ascii text. I havent tried pasting it into an ICON but I am sure its not going to work. So, how do you turn a .png into a .txt (or .docx, which my phone understands) ready for cutting and pasting? Alternatively how can the Android Prime see a .png? Stephen Lewkowicz (G1CMZ) https://my.numworks.com/python/steveg1cmz |

A .txt file is a plain text file, it only contains characters
A .png file is an image, a picture, you can not turn it in a .txt file, it would be like transforming a photo in a written text. |

PNG is an graphics file format with compression and encoding (no simple relation to pixels). See https://en.wikipedia.org/wiki/Portable_Network_Graphics
Maybe conversion from PNG to BMP (https://en.wikipedia.org/wiki/BMP_file_format) could be an attempt. |

The intention was to turn a PNG into something like an ICON - I am sure a read somewhere that ICON format was similar, though I cannot seem to find that thread again. I do not recall reading anything about it being similar to BMP.
Ages ago when I last used a hexadecimal editor, that would show the printable hex on-screen, but back then all I wanted to do was tinker with a few bytes and re-save the binary. I never needed to save the hex. Now, I am looking to save the binary as a readable hex file - and then see if that might be usable in an ICON. So, will any hex editor save the readable hex to a file? Is there such an editor built into Windows 7 (or can I do it on-line at the library - my own firewall has expired, so ideally i dont want to download an .EXE)? And then finally, will the Prime's ICON read that file format? Stephen Lewkowicz (G1CMZ) https://my.numworks.com/python/steveg1cmz |
