Inkscape 0.48 Illustrator's Cookbook

Overview of this book

Inkscape is an open source vector graphics editor with an intuitive user interface that has enough depth to make quality graphic designs with an attractive layout comparable to what you would make using Illustrator or CorelDraw. But choosing the right tool and the best approach to creating the desired effect can be challenging. Inkscape 0.48 Illustrator's Cookbook makes it super-easy for you to make your own vector-based graphics with the powerful Inkscape editor. Inkscape 0.48 Illustrator's Cookbook provides you with the latest recipes to quickly create scalable vector graphics. Recipes in this book teach you about some of the most useful time-saving features in Inkscape accompanied by a list of keyboard shortcuts that you can easily memorize. In addition to covering use of Inkscape tools and their advanced features, examples from the recipes uncover solutions to common graphics problems. The book starts off with familiarizing you with the tools and techniques in Inkscape that you can use to draw 2D shapes, calligraphic shapes, and 3D boxes easily. It then guides you through the most common color-changing steps performed in Inkscape along with some convenient procedures that can save your time when dealing with colors. It explains drawing using linear and radial gradients, which are irreplaceable, usage of clones to create interesting effects in illustrations, and live-path effects that can help you speed up constructing a shape and make the process more natural. You will learn how to make those tweaks on some of the ready-made filters, and in the final recipe we will create a filter from scratch. This practical book also contains recipes showing how to use Inkscape as a raster editor and how to achieve photo-realistic effects in Inkscape. For each important technique and skill, you'll see some simple recipes, then some more advanced recipes followed by an explanation of how Inkscape works to produce the desired effects in your illustrations. By the end of this book you will be confident enough to create your own vector-based graphics with Inkscape.

Tracing bitmaps

Tracing bitmaps is a way of getting a vector format for a raster image automatically. Inkscape comes with a tracing functionality, based on the Potrace™ software utility (http://potrace.sourceforge.net), that scans the image and calculates vector paths that fit the tracing options we have set previously.

In this recipe we will trace an image several times to see what options are available when tracing a bitmap, and compare the results.

How to do it...

The following steps will demonstrate how to trace a bitmap:

1. Import the Flower.png image into the document (Ctrl + I), embedding it.
2. Open the Trace Bitmap dialog by going to Path | Trace Bitmap... or by using Shift + Alt + B.
3. Under the Mode tab Single scan: creates a path set Brightness cutoff Threshold: to 0.5 and press the Update button in the Preview pane. Notice you get a black and white preview of the trace where the background is black and the flower is white.
4. Enable the Invert image option and press Update, the...
