convert image to 1 bit


Recommended Posts

closest you can get to actually converting to 1 bit is making it look like 1-bit: change to black and white, run halftone, then increase contrast to 100% (adjust brightness as desired)

Note:increase image size before running halftone on smallest dot size

If you only need it to look like 1 bit, then use my mini tutorial. The file will still be the size of a normal picture, but there will be only two colors: black and white.

You need to determine whether you need 1-bpp for stylistic reasons, or for bandwidth/storage reasons.

For stylistic reasons, the trick with Brightness&Contrast will work fine.

For bandwidth/storage, you can either save with another app (I'm sure GIMP can do it), or apply B&C, then save as whatever format, and then stuff it into a ZIP. Since every pixel will be #FF000000 or #FFFFFFFF, it'll compress really well.

It is simply a feature that not many people ask for, and so it's never been implemented. There's no technical reason that makes it impossible; the feature just isn't there.

Hi Friends!

Thanks again.

Well i´m going to try to explain my idea...

In my job i have a laser marking machine to work whith dxf files, but to do some things for me i now that the machine recognize pcx files in some conditions...

And the complete process of converting is, Foto in jpg with 16 bits, convert to 1 bit, black and white, floyd steinberg and finaly to pcx file.

Every time i have tryed, the result in the program from machine (LaserCad) is a black window( i think because much bits per pixel).

The idea is to engrave fotos on anodized aluminium.

Best regards

You can make it 1-bit (or look like 1-bit i don't know) by clicking save button on usaved image, then entering the name and choosing where you want to save it, click save, and then changing the Bit Depth to 1 bit. it si better than if you make it black and white and turning the contrast to 100% because it uses dithering and the file is maybe actualy 1-bit
