I spent the last couple days putting together a sixel image browser in Javascript. It lists a menu of directories containing image files. When the user selects one, it calls Imagemagick to convert the selected image to sixel format, and then displays the resulting sixel to the user. Imagemagick
conversion is pretty quick, depending on the size and complexity of the image being converted.

The mod requires SyncTERM. If a user runs it in a terminal other than SyncTERM, it offers a polite error message and quits.

For now I have it set up on my board to browse through stuff like the GIFs Galore CD and the Earth Science pictures of the day from fsxNet. So now users needn't necessarily download files from the board in order to view them.

I expect I'll spend more time giving it some more polish, but it's available in my doors menu if anyone wants to come try it out.

Actually, it also works on MagiTerm :) I was trying it out earlier. I did notice some differences when comparing the two.

* Syncterm displays the sixel while loading it, whereas magiterm waits for it to load before displaying it.

* Syncterm moves the cursor to the end of the sixel image, magiterm the cursor stays where it was when sending the sixel.

I'm guessing you're scaling images to fit to the screen with image magick as well as converting them? If so perhaps that could be an option, or just scale so the width fits? Syncterm / Magiterm both scroll sixel images that are to high for the screen.

As for width, Syncterm doesn't do any scaling / scrolling (as far as I can tell) Magiterm will scale images wider than the screen so they fit width ways.

Anyway, cool mod & well done :)

Nice to know it also works in MagiTerm! I didn't realize MagiTerm sent version info to SBBS like SyncTerm does. I'll amend my message based on this.

That's correct, I'm including scaling in the convert call because I wanted to ensure the entire image would fit in the terminal window. I did consider making the scaling optional, so maybe an enhancement for later.

Syncterm / Magiterm both scroll sixel images that
are to high for the screen.

That's interesting, because for me scrolling back in SyncTerm seems to destroy the sixel image; it just disappears completely. Maybe I'm doing something wrong?

Anyway, cool mod & well done :)

Much appreciated! Thanks for checking it out and sharing your findings.

Oh, sorry. yes scrolling back destroys the image. I just mean they scroll down as they are shown, rather than get cut off at the bottom.

Want!! Got some ideas and could put it to good use! :)

I tweaked my Sixel Gallery script a bit, adding an optional image path argument. If used, simply displays the specified image converted to sixel and ends. Using this small mod, I set up GIF, JPG, PNG, and BMP as Viewable File Types in SCFG. So now whenever someone browses directories containing images (e.g.: GIFs Galore CD-ROM), if they go into Extended Info for any image file and hit V to view it, they are shown a sixel preview of the image.

This same mod can be used in ansiview.js for artpacks containing image formats. I modded mine here so it shows a sixel version of any non-ANSI art file.

That's really cool! Care to share those mods?

Gladly! I just uploaded sixelgallery.js to Vert.

Hopefully my readme.txt makes sense. Let me know if any issues.

Sounds like something that could or should be added to gitlab so others have it available if they want to use it. Maybe discuss with echicken since I believe he wrote/maintains ansiview.

I have zero interest in it at the moment, so go nuts. :D
