Need python code $3.$x To satisfy the following instructions: The Python code you provided defines several functions for handling image optimization, PDF conversion, image extraction from PDFs$,$ and creating a PDF that includes both input data and output from a specific tool $($XIMAGEpdf$).$ Let's break down each part:

$1.$ optimize$\_$image Function:

Purpose: Optimizes a raster image for print by adjusting compression, resizing, and changing its color space.

Parameters:

image$\_$path: Path to the input image file. output$\_$path: Path to save the optimized image. compression$\_$quality: Quality of the image $(0-100),$ default is $80.$ resize$\_$factor: Factor to resize the image $($e$.$g$.,0\mathrm{.}75$ for $75\%$ of original size$),$ default is None. color$\_$space: Desired color space $($e$.$g$.,"$RGB$"$ or $"$CMYK$"),$ default is $"$RGB$".$

Process:

Opens the image. Resizes the image if a resize$\_$factor is provided. Converts the image to the specified color space if needed. Saves the optimized image with the given compression quality.

Example usage:

optimize$\_$image$("$input$.$jpg$",$ "output.jpg$",$ compression$\_$quality$=70,$ resize$\_$factor$=0\mathrm{.}75,$ color$\_$space$="$CMYK$")$

$2.$ convert$\_$to$\_$xerox$\_$metacode Function:

Purpose: Converts a PDF to Xerox Metacode format using the external tool XIMAGEpdf.

Parameters:

pdf$\_$path: Path to the input PDF file. output$\_$path: Path to save the converted Xerox Metacode file.

Process:

Constructs a command to call XIMAGEpdf $($an external tool$).$ Runs the command using subprocess.run$().$ Handles any errors and prints relevant messages based on the success or failure of the command.

Example usage:

convert$\_$to$\_$xerox$\_$metacode$("$input$.$pdf$",$ "output.xmc$")$

$3.$ extract$\_$images$\_$from$\_$pdf Function:

Purpose: Extracts images from a PDF file $($though the actual extraction is simulated here$).$

Parameters:

pdf$\_$path: Path to the input PDF file. output$\_$folder: Folder where extracted images should be saved.

Process:

Simulates the extraction of $3$ images $($in a real scenario, libraries like PyMuPDF or PDFMiner would be used to extract images from the PDF$).$ For each image, it creates a file with "simulated image data" in the specified output folder.

Example usage:

extract$\_$images$\_$from$\_$pdf$("$input$.$pdf$",$ "extracted$\_$images"$)$

$4.$ create$\_$pdf$\_$with$\_$data$\_$and$\_$ximagepdf Function:

Purpose: Creates a PDF that includes both the input data $($as text$)$ and the output from the Xerox Metacode conversion $($XIMAGEpdf output$).$

Parameters:

data: The input data to be included in the PDF$.$ ximagepdf$\_$path: Path to the Xerox Metacode file created by XIMAGEpdf. output$\_$pdf$\_$path: Path to save the final PDF file.

Process:

Creates a new PDF using reportlab's canvas. Adds the input data as text. Reads and adds the content of the Xerox Metacode file $($generated by XIMAGEpdf$)$ to the PDF$.$ Saves the generated PDF$.$

Example usage:

input$\_$data $="""$ This is some input data. It can be multi$-$line text. $"""$ create$\_$pdf$\_$with$\_$data$\_$and$\_$ximagepdf$($input$\_$data, "output.xmc$",$ "final$\_$output.pdf$")$

Key Libraries and Tools:

PIL $($Pillow$)$: Used for image handling, including opening, resizing, converting color spaces, and saving images.

subprocess: Used to run the external XIMAGEpdf tool for converting PDFs to Xerox Metacode format.

reportlab: Used for creating and manipulating PDFs$,$ including drawing text and saving files.

General Workflow:

Optimize an image $($resize$,$ compress, and adjust color space$).$

Convert a PDF to Xerox Metacode format.

Extract images from PDFs $($although this part is simulated in the code$).$

Create a final PDF that combines textual data and the converted Xerox Metacode output.

Error Handling:

Each function has error handling $($try$-$except blocks$)$ to catch and display any errors that might occur during execution, such as issues with file paths, tools not being available $($e$.$g$.,$ ximagepdf$),$ or other unexpected errors during image manipulation or PDF generation.
