Inkscape 0.48 has about 220 such filters that divide the program into 18 fairly intuitively named categories (from the Filter Effects The effects can be undone independently of the usual undo list, making experimentation a pleasure. As in photography, many filters can be layered. These filters act like true camera filters that are attached to lenses that distort and colorize the object. Menu) have added more depth and a little pizzazz. From Inkscape 0.45 (February 2007), however, so-called filters (from the Filters But, because the program makes use of simple color fills and gradients, its graphics have tended to look like cartoons. Lens Adaptersįrom the outset, Inkscape was capable of drawing complex shapes. Since my previous Inkscape article appeared in our sister publication Linux Magazine in 2005, nothing much has changed from Inkscape's solid base. Their smooth transitions and intuitive handling make them the digital equivalent of the French curve tool used by draftsmen. This article will deal primarily with basic shapes and Bézier curves, which use control points to form basic shapes. After the text is converted to paths the font will no longer be referenced and the design will be defined by the shape of the original font.Figure 1: The Inkscape drawing looks like a bitmap, but it's based exclusively on resolution-independent and Inkscape curve-tool editable vector curves. To convert the text to paths in Inkscape use the menu options “Path”-“Object to Path”. To avoid the possibility of the design changing when it is brought to a new computer you can convert the text to paths in Inkscape. This can dramatically change a design in some cases. The intended font may be swapped out for another font automatically. However if the font used in a design is not installed on the computer running K40 Whisperer. K40 Whisperer will convert text to paths for you when the design is loaded. You can use the dialog that opens to create the text then change the stroke color to red/blue to engrave/cut. To access the Hershey Text fonts in Inkscape go to “Extensions”-“Render”-“Hershey Text…”. There are a variety of stick fonts available in the Inkscape Extension for Hershey Text. If you don’t want to cut/engrave the outline of characters you will need to use a special font that consists of strokes not outlines, these fonts are commonly referred to as stick fonts. So if you want to vector cut/engrave a standard font you need to change the stroke color for the font, then you can vector cut/engrave the outline of the font. Text stroke color needs to be set in order to be interpreted as vector data.Īlthough text may look like strokes (depending on the font) generally standard fonts consist of outlines that are filled with a color. Text is a special kind of object usually defined by fill color. K40 Whisperer does not try to convert the filled portion of a shape to a vector path.ģ. Only the stroke colors are interpreted as vector cut/engrave features. Shapes/lines in SVG files have fill colors and stroke colors. Fill colors are not interpreted as vectors only the stroke colors for objects are converted to vector cut/engrave paths. The trace bitmap feature in Inkscape is located in the menu bar under “Path”-“Trace Bitmap”.Ģ. If you want to convert a raster image to vector engrave or cut paths you can use the bitmap trace feature in Inkscape to convert bitmap image to paths before sending the SVG file to K40 Whisperer. K40 Whisperer does not convert raster images to paths. If there is an image in the SVG file that contains blue or red the colors in the image are not recognized as a vector cut or engrave feature because the colored portion of an image is raster data not SVG path data. Blue and red colors in images are not converted to vectors. Here are a few of the common pitfalls that people encounter when reading SVG files into K40 Whisperer.ġ. A few people have experienced problems getting the red and blue lines to come into K40 Whisperer properly. In K40 Whisperer the red and blue vector paths in SVG files are converted to vector cut and vector engrave paths respectively.
