Structs
Low-level representation of an image
Reference to a chunk
Iterator of chunk metadata, returns ChunkRef which is like a slice of PNG metadata
Read an image with custom settings
Make an image with custom settings
Grayscale. Use .0 or * (deref) to access the value.
Grayscale with alpha. Use .0/.1 to access.
The RGB pixel
Enums
Position in the file section after…
Bitmap types.
Traits
Marker trait for “plain old data”.
Functions
Same as decode_memory, but always decodes to 24-bit RGB raw image
Same as decode_file, but always decodes to 24-bit RGB raw image
Same as decode_memory, but always decodes to 32-bit RGBA raw image
Same as decode_file, but always decodes to 32-bit RGBA raw image
Load PNG from disk, from file with given name. Same as the other decode functions, but instead takes a file path as input.
Converts PNG data in memory to raw pixel data.
Same as encode_memory, but always encodes from 24-bit RGB raw image
Same as encode_file, but always encodes from 24-bit RGB raw image
Same as encode_memory, but always encodes from 32-bit RGBA raw image
Same as encode_file, but always encodes from 32-bit RGBA raw image
Converts raw pixel data into a PNG file on disk. Same as the other encode functions, but instead takes a file path as output.
Converts raw pixel data into a PNG image in memory. The colortype and bitdepth of the output PNG image cannot be chosen, they are automatically determined by the colortype, bitdepth and content of the input pixel data.
