Flags used in the easy encoder API.

Flags are the same as the ones used in the img2sixel executable

Variants

OutFile = 111

Specify output file name

UseSevenBitMode = 55

Use sixel images for 7 bit terminals or printers

Default of the 2 bit mode flags

UseEightBitMode = 56

Use sixel images for 8 bit terminals or printers

HasGRIArgLimit = 82

Limit the arguments of DECGRI(‘!’) to 255

NumColors = 112

Specify the number of colors to reduce the image to

Defaults to 256

Renamed from “SIXEL_OPTFLAG_COLORS”

Mapfile = 109

Give a file that specifies a set of colors

Transforms the image to match the set

Monochrome = 101

Output a monochrome sixel image

Assumes the terminal background color is black

Insecure = 107

Connect to SSL sites without certs

Only applicable if libcurl is used

InvertBackground = 105

Assume the terminal background color is white

Only applicable when also using Optflag::Monochrome

UseHighColor = 73

Output a 15bpp sixel image

UseMacro = 117

Use DECDMAC and DEVINVM sequences to optimize GIF animation rendering

MacroNumber = 110

Specify a macro register number

ComplexionScore = 67

Specify the number of arguments for the score of complexion correction

Must be 1 or more

IgnoreGIFDelay = 103

Ignore delay when rendering GIF animations

StaticGIF = 83

Render an animated GIF as a static image

Diffusion = 100

Choose a diffusion method to be used with the NumColors option

Should be a DiffusionMethod DiffusionMethod: enum.DiffusionMethod.html

FindLargest = 102

Choose a method for finding the largest dimension of median cut boxes for splitting

Should be a MethodForLargest MethodForLargest: enum.MethodForLargest.html

SelectColor = 115

Choose the method for selecting the representative color from each median-cut box.

Only makes sense when the Optflag::NumColors is used

Should be a MethodForRepColor MethodForRepColor: enum.MethodForRepColor.html

CropRegion = 99

Crop a source image to fit some geometry

String format representation is “%dx%d+%d+%d”, which is width, height, x, y

Width = 119

Resize an image to a specified width

Uses the following syntax:

• auto

• <number>% scale with a percentage

• <number> scale a number of pixel counts

• <number>px scale a number of pixel counts

Height = 104

Resize an image to a specified height

Uses the following syntax:

• auto

• <number>% scale with a percentage

• <number> scale a number of pixel counts

• <number>px scale a number of pixel counts

Resampling = 114

Choose a filter for resampling when scaling the image due to Optflag::Width or Optflag::Height

Should be a ResamplingMethod ResamplingMethod: enum.ResamplingMethod.html

QualityMode = 113

Selects quality of color quanlization

Should be a QualityMode QualityMode: enum.QualityMode.html

LoopMode = 108

Select loop behavior for animated GIFs

Should be a LoopMode LoopMode: enum.LoopMode.html

PaletteType = 116

Select a palette color space

Should be a PaletteType PaletteType: enum.PaletteType.html

BuiltinPalette = 98

Choose a built-in palette type

Should be a BuiltinDither BuiltinDither: enum.BuiltinDither.html

EncodingPolicy = 69

#rgb
#rrggbb
#rrrgggbbb
#rrrrggggbbbb
rgb:r/g/b
rgb:rr/gg/bb
rgb:rrr/ggg/bbb
rgb:rrrr/gggg/bbbb

PenetrateScreen = 80

PipeInput = 68

Read source images from stdin continuously

Verbose = 118

Print debugging info

Version = 86

Print version and license info

Help = 72

Print a help message

Trait Implementations

impl Clone for Optflag

fn clone(&self) -> Optflag

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Optflag

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Optflag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Optflag

fn eq(&self, other: &Optflag) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
