3 Bitmap Preprocessing
Image Vectorizer provides various options for preprocessing images before converting them to vector format. Once you have imported an image in to the application you can access these options by clicking the 'Bitmap Preprocessing' button (or by using either the File menu or the keyboard shortcut ⌘1), to open the preprocessing panel.
The preprocessing panel is divided in to 4 sections (Fig.5):
- Section 1 contains rotate, flip and border controls.
- Section 2 contains color balance controls.
- Section 3 contains blur, sharpen and median controls.
- Section 4 contains image effects for halftone and outlining.
Preprocessing tips:
- You can toggle between the processed image and the original image by clicking the preview button to the left of the 'Bitmap Processing' button (You can also choose 'Preview Imported Image' from the 'File' menu or use the keyboard shortcut ⌘P).
- As well as adjusting the sliders, you can make precise adjustments by entering a value in the input field to the right of each slider.
- You can reset individual sections using the reset button, or you can reset all controls using the Reset all Filters button at the bottom of the panel.
- Some effect like blur make the image bleed out of its original size. You can increase the border to contain the effect.
- Halftone effects work great with photographic images.
- Brightness, contrast, and gamma are great for bringing out detail that might not get picked up during vectorization.
