New topic, as I managed to get a pleasing result. Converts Turing compatible photos into image editor-unreadable files. Saves small space on bmps. Feel free to criticize and edit. Released under most recent GPL. |

It crashed on me when i put in a 1424 * 2040 picture. (I wanted to test if you had thought about bigger pics) But other than that when i put in a small one it worked. good job, i did something like this a long time ago and you've made me want to uncover it again 
keep up the good work |

I have a version in the pic converter topic that can do larger pics. It's because this one needs an array to store all the data, so the more ram you have, the bigger pic you can do, sadly. However, unlike the other one, this one doesnt take 30 minutes to convert a 200x 200 picture. 
I'm still working on this, mostly cosmetic changes for the next one, but in future releases, I want to implement a library algorithm system, where you must have the right algorithmic 'library', to reconvert the photo back to bitmap. Oh and I fixed the second widows resizing, so no more always default size, thing. |

So... why? You're doing this so that people can't edit the images, but what's to stop someone from ripping them from screenshots? I always thought the point of this was to have something you can stick in the source code so that you only need to distribute the executable. |

It was, but I decided to create a new format that hid your bitmaps from anyone when transferring them, overly hopeful for a turing prog I know, but it gets me practicing.
Hopefully the "library" system I'm thinking of won't be too hard to implement..... Next update hopefully to include a crude version of that. Expect it in about a week or so. |

Enjoy, I managed to get the new feature in quick, although it's only a compression library, not an encodec library. And you can do any photo size without danger now.  |

YAY 
This is perfect, i'm creating a game and i hate having all those separte files when sending it to a friend (aka pics) this way i'll be able to text-ify them and compress into one file then un-text-ify. I did this myself, but my way was slow and i could only compress pictures that were the equivalent of my screen resolution (dont know why  )
This will work perfectly into the instalation program for my game. And of course i'll give credit to you  |

i dont see the point of this program. all it does is convert an image to essentially a bitmap without a header... why dont you just save it as a bitmap and add/remove bits from the header to make it unreadable. |

thats why its called "bit"map?  (i have no idea....)
but if this does reduce the picture size (memory), than what jpg can already do... then thats wow |

Heh, haven't gotten that far, and It'll never be done on turing, as I cant manipulate individual bits. I'll have to port it to my one other well known(relatively) language, C++. |

I never found how to in turing. Do you know how? |

Alright, just so everyone knows (though I'm certain Mazer doesn't care), this project hasn't died. Yet... I'm atm trying to figure a way to put in deflate or another compression method because inline (which the ones in here are) just don't cut it, and reduce size very little for the effort. If anyone has a feature suggestion, please post it here or pm me. Or if you want to help, that'd be nice . |

ALRIGHT I MANAGED TO PULL IT OFF WOOO! Okay enough with the overbearing noise, But I finally got a nagging problem out of the way. And installed a nicer looking method for input to boot! Welcome, oh modified (not much yet) button class of Cervantes! (I'll write a tutorial when I get around to that) Anyway changes:
As said above. Enjoy. |

lol, here i was looking forward to this i download it, and i cant run the .exe you didn't include all the files, apparently you left out a "checksum.prf"
(what the heck is a .prf anyway?) |

Surprised (i have no idea....) but if this does reduce the picture size (memory), than what jpg can already do... then thats wow simple definitions: ? BMP: pixel graphics. Mapping between bits of information per pixel and the colour that bit data represents? this translation is done via a bit map. Rather than sending data for each pixel in the BMP, we combine the data sent for adjacent pixels of the same colour. In this compression, no data is lost; full restoration of the picture is possible. ? JPEG: A bitmapped file that incurs loss of data. In this case, data is lost because pixels of a similar colour are given the same binary code, and then the above compression is applied. In this case, the accuracy/quality of the picture goes down.

(what the heck is a .prf anyway?) NOOO!! Don't run the exe! That's just a converter! It's supposed to search for the file written in checksum, compress it, and then delete checksum! Run the .t file marked HBM Converter V(0.5). Don't touch the exe's they will not run by themselves. |
