Which graphics are a fixed RESOLUTION.

Which graphics are a fixed RESOLUTION.

• A. Raster Images
• B. .PICT
• C. Vector Graphics
• D. .MPEG

Answer: (A)

Raster graphics are built from a grid of pixels, with a specific width and height in pixels. That fixes the resolution, so when you scale the image up, you usually see pixelation or blur because you’re enlarging the same set of pixels. Vector graphics, on the other hand, use mathematical descriptions of shapes, so they can be scaled to any size without losing clarity—the resolution isn’t fixed. MPEG is for video, which is a sequence of frames that end up rasterized for display, and PICT can contain either raster or vector data, so it isn’t inherently fixed in resolution. So the graphics with a fixed resolution are raster images.
