Flags used in the easy encoder API.

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

Variants

OutFile

Specify output file name

UseSevenBitMode

Use sixel images for 7 bit terminals or printers

Default of the 2 bit mode flags

UseEightBitMode

Use sixel images for 8 bit terminals or printers

HasGRIArgLimit

Limit the arguments of DECGRI('!') to 255

NumColors

Specify the number of colors to reduce the image to

Defaults to 256

Renamed from "SIXEL_OPTFLAG_COLORS"

Mapfile

Give a file that specifies a set of colors

Transforms the image to match the set

Monochrome

Output a monochrome sixel image

Assumes the terminal background color is black

Insecure

Connect to SSL sites without certs

Only applicable if libcurl is used

InvertBackground

Assume the terminal background color is white

Only applicable when also using Optflag::Monochrome

UseHighColor

Output a 15bpp sixel image

UseMacro

Use DECDMAC and DEVINVM sequences to optimize GIF animation rendering

MacroNumber

Specify a macro register number

ComplexionScore

Specify the number of arguments for the score of complexion correction

Must be 1 or more

IgnoreGIFDelay

Ignore delay when rendering GIF animations

StaticGIF

Render an animated GIF as a static image

Diffusion

Choose a diffusion method to be used with the NumColors option

Should be a DiffusionMethod

FindLargest

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

Should be a MethodForLargest

SelectColor

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

CropRegion

Crop a source image to fit some geometry

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

Width

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

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

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

Should be a ResamplingMethod

QualityMode

Selects quality of color quanlization

Should be a QualityMode

LoopMode

Select loop behavior for animated GIFs

Should be a LoopMode

PaletteType

Select a palette color space

Should be a PaletteType

BuiltinPalette

Choose a built-in palette type

Should be a BuiltinDither

EncodingPolicy

Choose an encoding policy

Should be a EncodePolicy

BackgroundColor

Specify a background color

Represented by the following syntax:

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

PenetrateScreen

Penetrate GNU Screen using DCS pass-through sequence

PipeInput

Read source images from stdin continuously

Verbose

Print debugging info

Version

Print version and license info

Help

Print a help message
