Some photos I try adding get stuck on analyzing pallet, and can’t be dithered unless I manually choose some colors. I’ve tried waiting on these photos for literally hours and it never finishes analyzing. I can’t really find a pattern, but the ones it does this on I’ve never been able to get to work.

:c would really like this fixed. I use this tool a lot. Any work arounds would be helpful too

Hello,
I have a problem when dithering. I want to dither a 128x296 PNG.

Thank you.

from @farteryhr on twitter:

but here's my only one more wish, please add gamma correction.. for reference, see: http://entropymine.com/imageworsener/ https://bisqwit.iki.fi/story/howto/dither/jy/

I would like to fix a few naming issues and add some more dithering matrices as a pull request, but I'm unable to find where they're actually located in your code, or are you using something external for the calculations?

Feature suggestion: improve UX by allowing to drag any compatible image directly to a drop zone on the homepage, a bit like squoosh.app do.

Possibility of using something like Squoosh API to further compress PNGs before download.

Hi there,

Thanks for the awesome tool ! Super cool !

There are only 2 things I don't understand and want to clarify :

• Why is the filesize larger than the original when we select the original image size ?
  
• Why is the filesize larger when we select the origin color palette than when we use black and white ?
  
  

Also, would it b possible to dither several images at once?

Thanks so much,
Damien

When dithering is set to black and white, the dithered images outputted are using 32 bit color depth, which is unnecessary as 1-bit depth could be used instead.

In the example images attached, the output from DitherIt is 9.31 KB:

If converted to 1-bit using a Python Script, we get a size of just 3.86KB, with no loss in image quality:

Would it be possible to add a conversion to 1-bit of BW color modes? I wouldn't mind writing the code and submitting a pull request if so.

Right now readme.md loads a gif, but the name of the file changes when the site is regenerated. Either the link should somehow update with the new name, or the gif should not be updated each time.

When you are done using the converter and try to download it, it downloads as an SVG but is encoded as a PNG.

I implemented a version of burkes dither with python, but when testing the same image, i found that the effect was quite different from your algorithm,and your result looked better. so i wanted to know what else besides the basic error diffusion op? and why?

Thx

Linked to the checkbox id so <label for="id"> can act as a button.

Something like ./ditherit-sli --dither-type=<> --output --pallete=<>

The current algorithm seems to treat transparent background as black. This is quite annoying when dealing with png images. I wonder if there is a option to reset all the transparent pixels in the input image to transparent in the output?

I uploaded all the frames of an animation and want to download them all now they're dithered but currently the only way to do that is manually going through each frame and clicking download.

Create ability to add "larger pixels", or "tiles" as done in RGBitsy.
