All Constants

Animated PNG chunks codes

Let the encoder choose the adequate codec

Default quality of color compression

Default difference between color quality and alpha quality

Specify that no information will be lost in the compression process

Let the encoder choose the adequate speed

Ongoing development in the next-generation video compression technology beyond AV1.

This decoding-only codec is developed by Google.

This encoding-only codec focuses on offering high performance and scalability.

Utilizing the YUV color space with 4:2:0 chroma subsampling, this format reduces both the horizontal and vertical resolution of the chroma channels by half relative to the luminance channel.

This format uses YUV color space with a 4:4:4 chroma subsampling.

it is a non-spacing mark

explicit end of paragraph (paragraph spacing below due to paragraph split)

RLE, LRE, RLO, LRO, PDF and BN are supposed to be removed

joins to the letter on the right (possible for joining type R and D)

zero-width joiner or non-joiner

this letter is to be combined to the right of previous letter

String constants for blend modes

Alias because linear or non linear multiply modes are identical

No bevel

Spacing only

Image Header: Contains image's size, depth and compression method

Background Color: Specifies the background color.

Physical Dimensions: Specifies the intended pixel size or aspect ratio for display.

static PNG chunks

Transparency: Contains transparency information.

Significant Bits: Indicates the color-accuracy of the source data.

Image Last-Modification Time: Stores the time that the image was last changed.

Image End: Marks the end of the PNG data stream.

Image Data: Contains image data which is compressed and possibly filtered.

Suggested Palette: Suggests a palette to use if the full range of colors is unavailable.

An alias for the linear blend, because it is faster than blending with gamma correction

A constant representing an empty point (with minimum possible integer values for X and Y) that can be used as a separator in a list of TPoint

A value for an empty rectangle with integer coordinates

Value indicating that there is nothing in the single-precision floating point value.
