This medium offers features such as: reverting actions, modifying content, colour palettes, layering, and sharing.
Drawing is a form of artistic expression. It entails utilising tools to make marks on a flat surface. Traditional media like pencils and charcoal have long been used. But nowadays I employ digital tools: a pen display and graphic design software.
I had a background in science, which included sketching fossils, crafting maps, and coding for computers. Now I create art using digital tools. The Graphical User Interface (GUI) has transformed creativity. It translates complex technical processes into visual, intuitive interactions.
I first bought a Sharp PC-1500 pocket computer a handheld computer with a plotter. That allowed me to create graphs. I next bought an Apple Macintosh 128K desktop personal computer. It featured a graphical interface. And I used it with an Apple ImageWriter dot matrix printer. An artist friend used this equipment to draw bitmaps. Nowadays in addition to using a mouse, I input spatial data with a stylus. And vector software represents geometric shapes.
I utilise layering techniques. And each piece of my digital artwork is unique.
Initially I worked with the raster graphics program MyPaint. Since then, I have switched to the vector graphics software Inkscape. These graphic representation methods create and store digital images differently. Raster uses pixel grids. But vector employs mathematical paths.
Raster graphics
A raster image is an array of tiny pixels. Most Internet images are raster; common formats are JPEG, PNG, and GIF. Raster images are compatible with various digital painting software. They are easy to edit. Raster images are compressible for reducing file size, though some raster formats may thereby lose detail. They can be used for a wide range of artistic applications. Raster images can store detail, and so are preferred for digital painting. But pixelation loses quality when scaled up. And high resolution file size can be large.
Vector graphics
Vector images are made of mathematical shapes. Scalable Vector Graphics (SVG) uses shapes, paths, text, and styles. Vectors are graphic representations that can be used as visual elements. Geometric primitives are points, lines, paths, polygons, rectangles, ellipses, arcs, Bézier curves, and splines. Points, lines and curves are fundamental geometric objects. Joining line segments forms a polygon. Commands define a primitive, specify coordinates, and set additional properties. The simplicity of these components enables the creation of clean and scalable illustrations. Some vector graphics are well-suited for printing due to their scalability.
