ABC (AmigAtari Bitmap Converter) v2.00
so... I stumbled across this software by Leonard of Oxygene. it creates absolutely spectacular results (converting PNG to HAM). but it seems I'm too stupid to create IFFs with it. I did search the internet for like two hours without any meaningful results. the utility creates two files: a bitmap and a palette binary. unfortunately I just don't know how I can get an IFF in the end. maybe somebody can enlighten me..?

It doesn't have IFF output.
As far as I know, there are no ready made RAW -> IFF converters around, only the other way. If you don't want to code one yourself, you could try the tool's PNG output mode and convert that to IFF, but it might degrade the HAM converter output somewhat. |

thnx! converting the PNG preview output is not going to help, I'm afraid... there's no way that this never before seen quality's going to survive a conversion with some other program.

![]() I didn't even thought people want to look at images with amiga iff image readers. But maybe it could be a nice option. I can add IFF export in the next version. |

I was hoping to find a utility to join the binaries, but it looks like no such thing exists. I compared the results to images created with ham_convert and I just didn't get results looking as good as the ones created with abc2.exe. plus, as a bonus, yours is working way faster. the possibility of exporting IFFs would be a very, very welcome addition... cheers, m. |

I fastly added a -iff export option that handle standard images and HAM. However I can't find any file format documentation for SlicedHAM (one HAM palette per line). Is that supported by IFF? ( I can find some SHAM riff description in some wiki page, but no details).
If anyone have a sliced ham IFF file (if it exists), I'm interested to look at the file for reverse engineering Last edited by leonard; 29 December 2023 at 20:28. |

I did create an IFF using ham_convert. as soon as the feature "sliced" is activated (it's marked as experimental) the output becomes garbled with a ton of artefacts...

Hi
![]() GIFMachine in Aminet contains source code for writing IFF SHAM files. |

so I just did a try, generated a SHAM file but xnview doesn't display it properly ( looks like xnview doesn't support SHAM chunk ).
I just tried with "irFanView" and it works properly! So it seems not so many viewers are supporting this format. Anyway I can do an update to AmigAtari bitmapConverter tomorrow with the new "-iff <filename>" export option Last edited by leonard; 30 December 2023 at 00:43. |

Yep, I was about to report for success on IrfanView but you have already found it.
I assume that on PC there aren't many programs that support the format.. On Amiga I tried "shamview" and the DOpus integrated "Show" and it worked well. There are probably others who support it too. |

thnks a lot, leonard! this additional option to export IFFs is very much appreciated, great stuff. one thing though: Microsoft Defender killed "abc2.exe" immediately when downloaded... this was not the case with version 2.00. might be a false positive of course.
EDIT: v2.00 also gives a red flag. VirusTotal abc2.exe v2.01 VirusTotal abc2.exe v2.0 Last edited by mikeboss; 30 December 2023 at 14:00. |

The other alternative is to put the exe in a zip and make a "release" in github, maybe it avoids that kind of thing |
