Common questions and issues

Key point #1

PBNify just takes an image as input and produces images as output. So any questions about how the outline looks when printed, or about what to do with the outline, or about your business idea, is beyond the scope of PBNify.

Key point #2

There are no hidden options or alternative versions of PBNify (at least that I have made). If you want a setting or feature that PBNify doesn't have, you'll have to copy and edit the source code. If it doesn't work as well as you want, you'll have to try something else.

Key point #3

PBNify runs on your computer, not on a server. It works fine on typical browsers on PCs/laptops. If it isn't working on your device, that is beyond my control.

I can almost guarantee one of those points addresses your issue, but here are some more detailed answers.

PBNify isn't running at all.

If you try selecting a palette and clicking "PBNify" and it doesn't start computing, then there could be a compatibility issue with your device or browser. Try running it from a different computer.

It's stuck on "identifying color regions..."

Usually it finishes within a minute, but it could take longer depending on the computer speed, having a lot of colors chosen for the palette, or having a very tall image. Hopefully changing one or more of those will get it to finish.

Is there an installable version / Can I run PBNify offline?

I do not have an installable version since it's written in web languages and would require substantial rewriting. However, since everything happens locally in the browser, you could in theory run PBNify offline. You'd have to download the repository, replace CDN references to local libraries, and run a local web server to serve PBNify from that directory.

How do I get better resolution in the outline?

You can use the slider to set the width before loading an image, and a higher number results in a more detailed outline.

How do I use a custom palette instead of choosing colors from the image?

There are two ways of doing this. You could use another program to recolor the image to include the colors you want, and then load that version into PBNify. Or, you can run PBNify with the original image, and then just replace the output palette with one containing substituted colors of your choosing.

What does all this color info mean and how do I use it to buy paints?

Those are different ways of specifying a color as used with computers and printers. The hex code (e.g. #386e97) and RGB give red/green/blue components, HSL gives hue/saturation/lightness, HSV/HSB gives hue/saturation/value(brightness), and CMYK gives cyan/magenta/yellow/black, which is used for printers. I included all of them in case they are helpful in obtaining paints for the palette colors, but I'm not sure which ones are actually used for that, if any. When I've done PBNs I've only mixed basic paints to approximate the colors.

How do I print the outline onto canvas?

I haven't tried printing onto anything except regular paper. But one way to get the outline onto canvas is to print it onto regular paper, place that on the canvas with graphite or carbon paper in between, and trace along the outlines and numbers.

Can I get the outline as vector graphics?

PBNify cannot provide a vector graphic because its algorithms are based on a pixel grid and directly create a raster image.

I don't know how to save the results.

This step can vary because different devices and browsers handle it differently. After clicking any of the "save" buttons, you should be able to right-click on the image and save it to file. If that doesn't work, try the "print to PDF" option when printing the page, which saves it as a PDF file. As a last resort you can screenshot and crop. You can do that from the main page if the tab that opens is blank.

I'd like to use PBNify's code for my project/business.

You are welcome to use, copy, and modify the code, including for commercial purposes, but I don't have time to help with it.

You may also use the PBNify output you create for commercial purposes, such as in a coloring book, as long as you aren't infringing copyright on the source images.

Here is my image, can you run PBNify for me?

Of course not. (Yes, people actually send unsolicited photos of their family members to me, a stranger on the internet. Don't do that.)
