Crate tina::lodepng

Modules

Bitmap
Low-level representation of an image
ChunkRef
Reference to a chunk
ChunkRefMut
ChunksIter
Iterator of chunk metadata, returns ChunkRef which is like a slice of PNG metadata
ColorMode
Color mode of an image. Contains all information required to decode the pixel bits to RGBA colors. This information is the same as used in the PNG file format, and is used both for PNG and raw image data in LodePNG.
CompressSettings
Settings for zlib compression. Tweaking these settings tweaks the balance between speed and compression ratio.
Decoder
Read an image with custom settings
DecoderSettings
Settings for the decoder. This contains settings for the PNG and the Zlib decoder, but not the Info settings from the Info structs.
DecompressSettings
Encoder
Make an image with custom settings
EncoderSettings
Error
ErrorCode
Grey
Grayscale. Use .0 or * (deref) to access the value.
GreyAlpha
Grayscale with alpha. Use .0/.1 to access.
Info
Information about the PNG image, except pixels, width and height
RGB
The RGB pixel
State
The settings, state and information for extended encoding and decoding
Time
The information of a Time chunk in PNG

ChunkPosition
Position in the file section after…
ColorType
Type for decode, encode, etc. Same as standard PNG color types.
FilterStrategy
automatically use color type with less bits per pixel if losslessly possible. Default: AUTO
Image
Bitmap types.

decode24
Same as decode_memory, but always decodes to 24-bit RGB raw image
decode24_file
Same as decode_file, but always decodes to 24-bit RGB raw image
decode32
Same as decode_memory, but always decodes to 32-bit RGBA raw image
decode32_file
Same as decode_file, but always decodes to 32-bit RGBA raw image
decode_file
Load PNG from disk, from file with given name. Same as the other decode functions, but instead takes a file path as input.
decode_memory
Converts PNG data in memory to raw pixel data.
encode24
Same as encode_memory, but always encodes from 24-bit RGB raw image
encode24_file
Same as encode_file, but always encodes from 24-bit RGB raw image
encode32
Same as encode_memory, but always encodes from 32-bit RGBA raw image
encode32_file
Same as encode_file, but always encodes from 32-bit RGBA raw image
encode_file
Converts raw pixel data into a PNG file on disk. Same as the other encode functions, but instead takes a file path as output.
encode_memory
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.
