In the resolution field, I typed 300 to replace 72. It is important to ensure that anti-aliasing is checked. (Anti-aliasing is a feature that smooths, or blends, adjacent pixels for a more pleasing and fluid visual appearance.) After clicking OK, Fig. 3 dis- plays the result. Sometimes this is all that is necessary to enhance an image, but in this case, the image was only a bit better — still without sharp delineation of objects. Another action that has proven some- what effective in enhancing an image is a PHOTO-PAINT feature known as poster- ize. This can be especially useful if a photo is to be power traced into a vector image. With the bitmap selected, click the edit bitmap icon. When the image opens in PHOTO-PAINT, go to image > transform > posterize; a dialog appears with a level slider. For this image, I chose (8) as the level. This essentially limits the number of colors to eight. It is good to enable the before-and-after view to monitor the changes visually. When you are happy with the result, click OK and save. Close PHOTO- PAINT and the modified image reap- pears in CorelDRAW. (Fig. 4 compares the original photo with the posterized ver- sion.) I selected the new posterized image and chose to trace it. Fig. 5 is the vector- ized version — ungrouped, I deleted the blue background. One could easily select the resulting objects and give them each a fountain fill to suggest a more photo- realistic appearance while still retaining the vector object characteristics. Caution: I have learned, over time, that before beginning any modification, it is good to keep a copy, or duplicate, of the original image in case something goes awry in the modification process. One can then access the original image and begin again. I have found that often it is most expedi- ent to simply redraw the object into a vector Fig. 1. Fig. 2. Fig. 3.
