What are bitmap image files suitable for?

# data[].attributes.body
Usually used for higher quality images that aren't for practical use, e.g. logos.

# data[].attributes.body
Usually large, due to saving individual pixel data.

# data[].attributes.body
Yes, not in the same way as vectors.

Do bitmap images have a separate outline and fill?

Do bitmap images have a separate outline and fill?

# data[].attributes.body
No, bitmaps images are stored as pixels, so instead of each shape or contour being essentially it's own image, the entire image is treated as one.

# data[].attributes.body
bitmap files are made out of individual pixels, each with a specific location and with a colour. the size of bitmap files is based on how many pixels they have and how many colours the pixels can be.

Do vectors have a separate outline and fill

# data[].attributes.body
Vectors consist of shapes made up of mathematical equations, meaning the outline is one set and the fill is another.

Files usually take up a considerable amount of space so compressing the file decreases the file size so you can save more files on your computer. It is useful to compress files on a website so users with slower internet speed can get onto the site with little to no problems.

lossless compression is a form of data compression that decreases size without losing any information.
it works by finding patterns in the data, using data trees to organize the information and reducing the size of commonly used strings of bits.
it is used when data integrity is important, such as programs or consistently high resolution image/video.

vector files, instead of being made out of individual pixels like bitmap files, are comprised out of mathematical equations, more specifically, the file defines a variety of vectors, their magnitude and direction in 2 dimensions, and other attributes like colour.
the CPU is the brain of the computer

What is lossy Compression?                                Lossy file compression results in lost data and quality from the original version. Lossy compression is typically associated with image files, such as JPEGs, but can also be used for audio files, like MP3s or AAC files.

To compress a file is to reduce the overall size. This is done by an algorithm that will find and remove as much redundant data as possible. An example of this would be plain text in a word processing document being replaced by numbers or another kind of identifier. The identifiers are saved as a key in the newly compressed document, for example the word "and" may be saved as the number 5, and the more times the word is used the more efficiently compressed the file will be.

Binary files such as applications and disk images can also be compressed, again with an algorithm which locates repeating patterns. However once a file like this is compressed it must be decompressed before use, using a file decompression application.
