<h1>Common questions and issues</h1>
<h4>PBNify isn't running at all.</h4>
<p>
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.
</p>
<h4>It's stuck on "identifying color regions..."</h4>
<p>
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.
</p>
<h4>Is there an installable version / Can I run PBNify offline?</h4>
<p>
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 <a href="https://github.com/daniel-munro/pbnify">the
repository</a>, replace CDN references to local libraries, and run a
local web server to serve PBNify from that directory.
</p>
<h4>How do I get better resolution in the outline?</h4>
<!-- <p> -->
<!-- PBNify always resizes the input and output images to a width of 800 -->
<!-- pixels. However, if the image is wider than it is tall, you could -->
<!-- rotate it beforehand. Then, the smaller dimension will be set to -->
<!-- 800px, and would allow for more detail. -->
<!-- </p> -->
<p>
You can use the slider to set the width before loading an image, and
a higher number results in a more detailed outline.
</p>
<h4>How do I use a custom palette instead of choosing colors from the
image?</h4>
<p>
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.
</p>
<h4>What does all this color info mean and how do I use it to buy
paints?</h4>
<p>
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. If you find out what color specifications
are used to buy custom paint colors, let me know and I'll add it!
</p>
<h4>How do I print the outline onto canvas?</h4>
<p>
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.
<!-- so I'm
not sure how to do it. If you find a way, let me know and I'll put
it here. -->
</p>
<h4>Can I get the outline as vector graphics?</h4>
<p>
PBNify cannot provide a vector graphic because its algorithms are
based on a pixel grid and directly create a raster image.
</p>
<h4>I don't know how to save the results.</h4>
<p>
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.
</p>
<h4>I'd like to use PBNify's code for my project/business.</h4>
<p>
You are welcome to use, copy, and modify the code, including for
commercial purposes. I don't have time to help with business
ventures, but I'd love to see what you do with it.
</p>
<p>
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.
