Piirtämisohjelma

Piirtämisohjelma, also known as drawing software or graphics editor, is a computer application used to create, edit, and manipulate digital images. These programs range from simple tools for basic sketching to complex professional suites capable of intricate graphic design, illustration, and photo editing.

The functionality of drawing programs varies widely. Some offer raster-based editing, where images are composed of pixels, allowing for detailed photo retouching and painting-like effects. Examples include Adobe Photoshop and GIMP. Others are vector-based, creating images from mathematical equations that define lines, curves, and shapes. This approach ensures that images can be scaled to any size without loss of quality, making them ideal for logos, illustrations, and typography. Popular vector drawing programs include Adobe Illustrator and Inkscape.

Many drawing programs provide a wide array of tools such as brushes, pencils, erasers, shape tools, text editors, and color palettes. Advanced features might include layers, masks, filters, gradients, and animation capabilities. They can be used for a multitude of purposes, including digital art, web design, technical drawing, and scientific visualization. The choice of a piirtämisohjelma often depends on the user's specific needs, skill level, and the type of work they intend to produce.
