Inkscape won't magically convert any raster graphics included in the document into vector graphics. However, Inkscape can help you to extract the photo. You can tell that a graphic is a raster image in Inkscape 0.47 if after selecting the graphic and choosing Object > Ungroup, you cannot select individual elements.
Potrace's input and output is black and white (colored images are greyscaled before processing). However, Inkscape is capable of producing color images by decomposing each channel into several black and white images and tracing them separately with Potrace. The commercial Total Vectorize program also uses Potrace as its core.
Before learning how to convert PDF images to SVG images it may be useful to learn how to extract images from PDF documents and create PNG, GIF, and JPG images. By using Adobe Reader many images in PDF documents can be right-clicked, copied, and then pasted into any image editor. A popular, free image editor good for beginners is IrfanView ...
In this lesson, I move to a vector software, either Inkscape (free) or an other. My objective is to add in a clean way —visually and within the SVG code— all the semantic layers. The semantic layers including: the legends' icons and labels, the map scale, north arrow, localizator, the topographic legend.
As these are vector graphics, the images can be scaled to any size, large or small, without loss of quality. Inkscape is a free program used to edit vector graphics. Inkscape provides a graphical user interface for the editing of such diagrams, using the standard Scalable Vector Graphics (SVG) format. [1]
It can also load and handle SVG files created with other software like Inkscape. Inkscape is a free and open-source vector editor with the primary native format being SVG. Inkscape is available for Linux, Windows, Mac OS X, and other Unix-based systems.
Some molecule editors (e.g. ChemSketch) can produce WMF files which can be read by recent versions of inkscape. One way to do this is to export the file to a TIFF as well as a WMF. You can then use the TIFF as a background image to get the label placement as accurate as possible. The process is basically as follows:
