Image vectorization is a process that converts raster graphics into vector graphics. This transformation is vital in various fields, from graphic design to digital art.
The document "Vectorize Test Info" offers insightful guidelines on how to effectively vectorize different types of images. Here’s what beginners need to know:
1. Preparing for Vectorization:
Background Removal: Before vectorizing, it's essential to clear the background to a solid color. This step is crucial because backgrounds can contain unnecessary details that complicate the vectorization process.
2. File Size Considerations:
Impact of Background Removal: Removing the background can increase the file size due to the creation of extra surfaces at the borders of opacity. It's often better to remove the background later using a vector editor.
3. Black & White Vectorization:
Color Perception: In black and white vectorization, light and warm colors are perceived as white, while dark and cold colors are seen as black. Adjusting these colors and the image's brightness in a graphic editor can yield the desired vector image.
4. Dealing with Artifacts:
Background Removal in Black & White Mode: Removing the background during vectorization in this mode can lead to artifacts. It's recommended to perform this step later in a vector editor.
5. Test Results and Best Practices:
"Vectorize Test Info" includes various tests with different presets and custom settings to find the optimal balance between quality and file size. The 'Polygon Custom settings' was found to be the best choice in most cases.
6. Different Image Types:
"Vectorize Test Info" explores vectorization techniques for various image types like flat illustrations, pixel art, cel-shaded, 3D, and photographs. Each type requires specific considerations for optimal results.
7. Detailed Observations:
"Vectorize Test Info" provides comparisons of file sizes for different vectorization methods, helping users understand the trade-offs between image quality and file size.
In conclusion, the "Vectorize Test Info" document offers valuable insights into the art of vectorization, highlighting the importance of background removal, color adjustments, and choosing the right settings for different image types. For anyone starting in the field of digital art or graphic design, understanding these fundamentals is crucial for creating high-quality vector images.
