created from rows of different colored pixels that together form an image. In their simplest form, bitmaps have only two colors, with each pixel being either black or white.

Quality of Bitmaps - reduction and enlargement.

# data[].attributes.body
Bitmap images are organised as a grid of coloured squares called pixels, pixels is short for "Picture elements", when zooming in or enlarging a bitmap images, the pixels are forced to strech and get bigger, making them larger blocks. This is why bitmap images appear as poor quality when enlarged to much.

# data[].attributes.body
When enlarging a bitmap image, you can see the individual pixels that make up an image. This means that the pixels get bigger. This differs from vectors because bitmaps do not use mathematical formulas to draw lines and curves.

Do they have have separate outline and fill? (bitmap)

# data[].attributes.body
The there is no sepereate outline and fill, for there is no specific shapes, only pixels set to a certain colour meaning that there can be no seperate parts.

They are suitable for rasterized and pixelated data e. g. digital photographs. It can also be used for the websites and for printing materials.

Quality of vectors - reduction and enlargement

# data[].attributes.body
Vector graphics are not composed of pixels they are resolution independent. Vectors can be scaled to any size without losing quality. This means they can be enlarged or reduced in size.

# data[].attributes.body
file size depends on what the file is. for example image files like .png is much smaller than a .exe file which is a program. If this is an image then it depends on how much you have compressed this image, if you compress it all the way down to 10% then the image will look much worse but you will still be able to make it out. It also depends on that kind of file this is. For example, a .pdf file is much larger than a .jpg file.

Grouping takes two or more vectors and creates a single object (group) that can be moved around and manipulated without the individual vectors changing their position relative to each other.

At any time, Grouped vectors can be ungrouped to allow changes to be made.

Quality of enlargement or reduction vectors

# data[].attributes.body
Enlargement is able to be done easily and to a good quality due to the way that vectors work. Vectors work by setting the correct coordinates and working by saying draw line from x to y- a way to create the image without data being stored, for the data stored is just how to make the lines. Reduction is the same, vectors do not get better or worse quality like bitmaps do.

# data[].attributes.body
Vector graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way. A path can be a line, a square, a triangle, or a curvy shape.

Thy are not made up from a grid of pixels.
They are made out of mathematical curves and paths instead pixels.

In information technology, lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content.
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. The "lossyness" of an image file may show up as jagged edges or pixelated areas.

# data[].attributes.body
Lossless compression is where photos or audio/data of some sort are modified to have extra bits deleted, as in with lossless data that is not needed like extra binary digits that are not used are wiped, parts that are not needed and will not be noticed when deleted are destroyed to save space. Vectors are used as

Images in GIF and JPEG formats are lossy, while PNG, BMP and Raw are lossless formats for images.

Audio files in OGG, MP4 and MP3 are lossy formats, while files in ALAC, FLAC and WAV are all lossless.

In information technology, lossy compression, which is also known as irreversible compression is the class of data encoding methods that use inexact approximations and it discards the data to display the content. These are techniques to reduce data size for storing, handling and sending content.

ADEEL
A form of compression that reduces digital file sizes by removing data.

lossless
A form of compression that encodes digital files without losing detail. Files can also be restored to their uncompressed quality.

Compression can be lossy or lossless. Lossless compression means that as the file size is compressed, the picture quality remains the same - it does not get worse. Also, the file can be decompressed to its original quality. Lossy compression permanently removes data.
