ICT Quarter 1 Vector & Raster Images

Raster Images

• bitmaps

• rich details and pixel-by-pixel editing

• rendering complex, multi-colored visuals

• photo editing and creating digital paintings

Vector Images

• paths with mathematical formulas

• scaled infinitely

• simple, solid colors

• logos, illustrations, engravings, etchings, signages

Raster File Types

• BMP

• TIFF

• PCK

• GIF

• PNG

• JPEG

Vector File Types

• AI

• EPS

• CGM

• PDF

• SVG

• CDR

Raster Images (2)

• comprised of pixels, arranged to form an image

• constrained by resolution and dimensions

• capable of rich, complex color blends

• large file sizes (but can be compressed)

• Photoshop and GIMP

• perfect for “painting”

• capable of detailed editing

Vector Images (2)

• comprised of paths, dictated by mathematical formulas

• infinitely scalable

• difficult to blend colors without rasterizing

• small file sizes

• Illustrator, CorelDraw, Inkscape

• perfect for “drawing”

• less detailed, but offers precise paths

When Should You Use a Raster?

• photographs and scans

• detailed digital art

• specific web use

When Should You Use a Vector?

• logos and branding

• illustrations and type

• large-format prints

• manufacturing and engraving

GIF

It is a raster file type meaning "Graphics Interchange Format", designed for web use, primarily for simple graphics, logos, and animations.

EPS

It is a vector file type meaning "Encapsulated PostScript", used for text and graphics, often in professional printing.

PNG

It is a raster file type meaning "Portable Network Graphics", supports transparency and lossless compression, ideal for web images and logos.

PDF

It is a file type meaning "Portable Document Format", can store text, images, and graphics, used for sharing and printing documents. It supports both raster and vector elements.

AI

It is a vector file type meaning "Adobe Illustrator", the native format of Adobe Illustrator, used for creating and editing vector artwork.

BMP

It is a raster file type meaning "Bitmap", stores images pixel by pixel, uncompressed, with large file sizes but high quality.

SVG

It is a vector file type meaning "Scalable Vector Graphics", web-friendly and XML-based, scalable without losing quality, ideal for icons and logos.

CGM

It is a vector file type meaning "Computer Graphics Metafile", often used in technical illustrations, CAD, and engineering diagrams.

CDR

It is a vector file type meaning "CorelDRAW", the native CorelDRAW format, used for vector designs like logos, brochures, and signs.

TIFF

It is a raster file type meaning "Tagged Image File Format", a high-quality format used in photography and printing, supports lossless compression.

PCX

It is a raster file type meaning "Picture Exchange", one of the earliest raster formats, once popular in old graphics programs but now outdated.

JPEG/JPG

It is a raster file type meaning "Joint Photographic Experts Group", a widely used format with lossy compression, best for photos and web use.
