<h1>Vectorize Bitmap</h1>
|
|
|
|
<p>Sometimes, we may have a raster image (JPG, PNG ...), which used to be a vector image.
|
|
The original vector image can be recreated by hand, but it may take a lot of time.
|
|
Photopea can do it automatically, it is called <b>bitmap vectorization</b> or <b>bitmap tracing</b>.</p>
|
|
|
|
|
|
<p>After we open our raster image (or select the right layer in a layered image),
|
|
press Image - Vectorize Bitmap. We will see a special Vectorizer window.</p>
|
|
|
|
<a href="//blog.photopea.com/wp-content/uploads/2018/02/vectorize.png">
|
|
<img src="//blog.photopea.com/wp-content/uploads/2018/02/vectorize.png" class="fullw" />
|
|
</a>
|
|
|
|
<p>We can see the original image on the left and the vector image on the right. We can move both images with a mouse, or zoom in / out with a mouse wheel.
|
|
We can also set two parameters:
|
|
<ul>
|
|
<li>Number of colors</li>
|
|
<li>Noise reduction</li>
|
|
</ul>
|
|
The need of the noise reduction is detected <b>automatically</b> for each image and we recommend not to change that setting.
|
|
Once we are satisfied with the vector output, hit OK.
|
|
Our original raster layer will be replaced with corresponding vector layers,
|
|
ready for an additional vector editing, or for the export as vector graphics: SVG or PDF.</p>
