is it is true that flash makes extensive use of scalar graphics
Answers
yes...
flash is a simple tool for creating graphics movies and games.
even i have tried it...
it uses a lots of physics...
please mark as brainliest
I think you mean raster graphics.
You see, in Physics, we have vectors and scalars. In computer science, graphics are either vectors or rasters. Rasters are images with data for each pixel and cannot be scaled up without a loss in quality. Vectors, on the other side, store data about lines, points and fills, which can be scaled up easily without any loss in quality.
Here's what Flash does. When you create something like a shape, it uses that in its vector form, so that you can easily scale it up or down when required. On the timeline, though, it has to rasterize it in order to display the shape. If you scale it up, however, it won't pixelate.
That is not the case with images and external media imported into Flash. External png/jpg/gif images (svg and epf are exceptions) are fundamentally raster images and cannot be converted to vector images.
To conclude, Flash uses vector graphics unless the something is an external file which is in a fundamentally raster format. It obviously prefers using vectors over rasters.
