PBM to Jack Converter

Overview

This project provides a single HTML file to convert PBM (Portable Bitmap) files to Jack language functions, specifically designed for the Nand2Tetris project. The tool reads a PBM file and generates a Jack function to draw the image in memory.

Requirements

• The PBM file must be of type P1 (plain PBM format).
• The image width must be a multiple of 16 pixels.

Usage

1. Open the index.html file in a web browser or use the netlify link (https://pbm2jack.netlify.app/).
2. Select a PBM file.
3. The converted Jack code will be displayed in the output textarea.

How It Works

1. The user selects a PBM file.
2. The file is read and processed:
   • Comments and empty lines are filtered out.
   • The file type is checked to ensure it's P1.
   • The image dimensions are extracted and validated.
   • The pixel data is concatenated into a single string.
3. The pixel data is processed column by column, converting each 16-bit wide column into a signed decimal integer.
4. A Jack function is generated to draw the image in memory.
