<# .SYNOPSIS Generates ASCII art text using a specified FIGlet font and options. .DESCRIPTION This function converts input text into ASCII art using the specified FIGlet font and rendering options. It processes each line of the input text, generates FIGlet lines for each, and combines them vertically to produce the final ASCII art output. .PARAMETER fontName The name of the FIGlet font to use for generating the ASCII art. .PARAMETER options A hashtable containing options to override the default font settings, including: - `width`: The maximum width of the output text. - `fittingRules`: Rules for horizontal and vertical smushing. - `printDirection`: The direction in which the text is printed (e.g., left-to-right or right-to-left). .PARAMETER txt The input text to be converted into ASCII art. .EXAMPLE $fontName = "Standard" $options = @{ width = 80 fittingRules = @{ hLayout = [LayoutType]::ControlledSmushing vLayout = [LayoutType]::UniversalSmushing } printDirection = 0 } $txt = "Hello, World!" $asciiArt = Generate-Text -fontName $fontName -options $options -txt $txt This example generates ASCII art for the text "Hello, World!" using the "Standard" FIGlet font and the specified options. .NOTES This function assumes the existence of helper functions such as `Generate-FigTextLines` for generating FIGlet lines and `Smush-VerticalFigLines` for combining FIGlet lines vertically.
