class documentation

class TIPicture(PictureEntry): (source)

Constructor: TIPicture(init, for_flash, name, version, ...)

Parser for color pictures

A TIPicture is a 266 x 165 grid of pixels which can take on any of the 15 standard colors. Each pixel comprises a single nibble, which stores an (offset) index into the color palette.

def __init__(self, init=None, *, for_flash: bool = True, name: str = 'Pic1', version: int = None, archived: bool = True, data: bytes = None): (source) ¶

overrides tivars.var.TIEntry.__init__

Creates an empty entry with specified meta and data values

The entry version and archived flag are invalid if for_flash == False.

Parameters
init	Values to initialize the entry's data (defaults to `None`)
for_flash:`bool`	Whether the entry supports flash chips (defaults to `True`)
name:`str`	The name of the entry (defaults to a valid default name)
version:`int`	The entry's version (defaults to `None`)
archived:`bool`	Whether the entry is archived (defaults to entry's default state on-calc)
data:`bytes`	The entry's data (defaults to empty)

def array(self) -> list[list[pixel_type]]: (source) ¶

overrides tivars.types.picture.PictureEntry.array

Returns
`list[list[pixel_type]]`	A two-dimensional `list` of the pixels in this picture

def get_min_os(self, data: bytes = None) -> OsVersion: (source) ¶

overrides tivars.var.TIEntry.get_min_os

Determines the minimum OS that supports this entry's data

Parameters
data:`bytes`	The data to find the minimum support for (defaults to this entry's data)
Returns
`OsVersion`	The minimum `OsVersion` this entry supports
