Image Conversion [message #366486]

I have some JPG/PNG/etc images that I want to convert to HGR and DHGR.

The Buckels "b2d" converter throws a "bad PNG" error on whatever I try. The "tohgr" converter gives an error saying it can't load the JPG library, while PNGs give another error.

Is there anything out there?

Did you try Super Convert 4 for the Apple IIgs? It recognizes JPEG/JFIF files but not PNG files which you can try converting to GIF or JPEG at first

SuperConvert4 is excellent for the job but requires GSOS. Also requires a Dbl hi-res matching palette and a screen grab for 140 x 192 from the super hi-res screen. I can help with those.

when using "tohgr" or Bill's "b2d", you might have better luck converting to a bitmap first.

Buckshot is exactly what I was looking for. Nice that you can try different settings on the fly. Looks like it uses b2d which I'd like to figure out for batching. My guess is Photoshop CS6 is writing some metadata to the BMP file that b2d doesn't like. Buckshot seems to write a temp image file to /var when converting so that's an option. I just wanted to avoid doing 17 steps.

Ironically I just put my gs in storage and got my ][+ out. I don't think it has enough RAM for superconvert though (1.125mb rom 3).

Super Convert 4 does support PNG. It is under Computer-independent.

That's not one of my error messages... so at the risk of calling
BullSh*torama I'll refrain from further remarks except to say keep
defammatory cr*p to yourself if you want my help... besides my converters
work with BMP files only... not PNG files.

I'd suggest you try harder and RTFM and source code. The references to the
various web pages were reposted at length recently in
comp.sys.apple2.programmer.

Also I know that tohgr works as advertised, and I have used the same
extensively without problems.

We aren't writing programs that don't work. You need to get The GIMP and
ImageMagick etc. (some decent image studio tools) if you are going to work
with bitmapped graphics.

Regards,

Bill

I don't recall spending more than 10 minutes on it, so at your suggestion I can take another look. It's helpful that Buckshot shows the command line switches for b2d I was potentially missing. My work history is in retouching/imaging so I'm most familiar with Photoshop. Additionally, I refuse to use a tool whose name is a synonym for a bondage suit. Can you imagine a retouching studio manager "uhh hey boss we can save money using GIMP instead of Photoshop"? It's just hard to take seriously. ImageMagicks' name is similarly problematic, for other reasons. I don't know who 'brands' these open source tools but the names are frequently horrible. Buckshot is pretty good name though. Funny yet also alludes to what the program does.

Open source program names have never been known for marketability.

Gimp's name is actually descriptive in this case -- it's still gimped compared to Photoshop.
i.e.

* Can you change the background transparent grid color? Nope.
* Does it have all the layer blend modes of Photoshop? Nope. https://imgur.com/C2iYdMl

Actually b2d was saying "PNG bad format" or something like that. Did an image resize to the BMP and now it works.

Just batch converted 5,692 images to HGR.
