![]() ![]() ![]() Raster (Bitmap) images - generally refer to photographs, pictures - with great color detail, but can’t enlarge without becoming blurry. Popular Vector file format extensions include: EPS, AI, CDR, PPT/PPTX, WMF/EMF, SVG, et al. Generally Vector images are created through the process of drawing with vector illustration programs such as CorelDRAW, Adobe Illustrator, or PowerPoint. Because vector images scale up or down without the loss of image quality, they can be output at any resolution both on screen and in print. The math is simply recalculated to produce an object twice the size of the original. For example a 1″ square object would need to be multiplied by a factor of 2 in order to double in size. When an illustration (drawing) program sizes a vector image up or down, it simply multiplies the mathematical description of the object by a scaling factor. They can be scaled up or down without any loss of quality. Vector images are made of lines and curves (or paths). Popular Raster file format extensions include: JPG/JPEG, GIF, PNG, BMP, TIFF, et al. Majorities of images on the Internet are Raster images as well. Pictures taken from a camera are Raster images. Generally Raster images are created through the process of scanning source artwork or "painting" with a photo editing or paint program such as Corel PhotoPAINT or Adobe PhotoShop. Spreading the pixels over a larger area causes the image to begin to lose detail and clarity. Increasing the number of pixels or making the pixels bigger in an image results in the original data being spread over a larger area. When you attempt to increase the size of an image created in a raster based program, the pixels defining the image can be increased in either number or size. They are created using a grid of pixels to define the image. Each pixel is a tiny square with assigned color value. Every shape is composed of thousands of pixels which is why we cannot see individual squares while looking at a bitmap image. Raster (Bitmap) images are composed of pixels. There are two types of images in the digital world - Raster (also called Bitmap) and Vector. The second, let's explain the difference. The Raster (Bitmap) image becomes blurry when enlarged, however the Vector image keeps the same resolution regardless of enlarging the size. No - if images are Raster (Bitmap) graphicsįirst, take a look at the following example.

Video Card: Nvidia GeForce 7300 Turbocache 256MB I get the impression that 'at the end of the day' Trace/or not, or even using Inkscape itself is all dependent on the quality of the final image, after zooming or transforations (ref. Is there a button that allows continous zooming/reduction? I can't see one! It's case by case whether you need to use Bitmap Trace or not when adding raster images in Inkscape.ġ2 If I needed to alter the raster image data (filters, color, etc.) or canvas size later I would have considered using Bitmap Trace first. In this case Bitmap Trace was not required because the result is acceptable. When zooming in or out the vector data stays crisp, only the raster data is slightly distorted. The image looks good because it still has all the original raster data in a static view. I opened this JPG in Inkscape (the raster data was not altered) and added the stars and text. ![]() I've attached a SVG that contains vector and raster data. If you're simply adding a PNG or JPEG to a static SVG canvas Bitmap Trace is not required. Bitmap Trace should be used when you plan to alter that data. ![]() Inkscape's native file SVG is a vector format although it can be a container of raster image data. ![]()
