Add drawImage method for rendering images to screen

[Copilot]

Plan to Add Image Drawing Support

• Explore repository structure and understand codebase
• Add drawImage method to Graphik class
  • Method signature: drawImage(self, filePath, xpos, ypos, width, height)
  • Use pygame's image loading and blitting functionality
  • Scale image to specified dimensions
  • Add error handling with exception chaining using from e
  • Rename parameter from file_path to filePath for naming consistency
• Create and run comprehensive tests to verify the implementation
• Update .gitignore to exclude Python cache files
• Run code review and address feedback
• Run security checks (CodeQL)

Changes Addressing PR Feedback

Comment 2752287803 - Parameter Naming Consistency

• Renamed file_path parameter to filePath to match existing naming style in the class (e.g., colorBox, colorText, sizeText)

Comment 2752287807 - Exception Handling Improvements

• Improved exception handling to use exception chaining with from e
• Preserves original traceback context for better debugging
• Maintains original exception types (FileNotFoundError, pygame.error)
• Provides descriptive error messages while keeping full error context

Implementation Summary

The drawImage method:

• Parameters: filePath, xpos, ypos, width, height
• Functionality: Loads image from file, scales it to specified dimensions, and draws it at the specified position
• Error Handling: Catches FileNotFoundError and pygame.error, re-raises with descriptive messages using exception chaining
• Testing: Comprehensive tests verify correct functionality including scaling, error handling, and exception chaining

Security Summary

• CodeQL analysis completed: 0 alerts found
• No security vulnerabilities detected in the implementation

Pull request overview

Adds a drawImage API to the Graphik class to support rendering image files onto the pygame display surface with explicit positioning and scaling.

Changes:

• Add Graphik.drawImage(...) that loads an image from disk, scales it to (width, height), and blits it to the display surface.
• Add error handling for image load/transform failures with a more descriptive exception message.
• Update .gitignore to ignore Python bytecode artifacts (__pycache__, *.pyc).

file_path is the only snake_case parameter name in this class (others use xpos, ypos, colorBox, etc.). To keep the public API consistent, consider renaming it to match the existing style (e.g., filepath or filePath).

Suggested change

	def drawImage(self, file_path, xpos, ypos, width, height):
	try:
	image = pygame.image.load(file_path)
	image = pygame.transform.scale(image, (width, height))
	self.gameDisplay.blit(image, (xpos, ypos))
	except (pygame.error, FileNotFoundError) as e:
	raise type(e)(f"Failed to load image from '{file_path}': {e}")
	def drawImage(self, filePath, xpos, ypos, width, height):
	try:
	image = pygame.image.load(filePath)
	image = pygame.transform.scale(image, (width, height))
	self.gameDisplay.blit(image, (xpos, ypos))
	except (pygame.error, FileNotFoundError) as e:
	raise type(e)(f"Failed to load image from '{filePath}': {e}")

Renamed parameter to filePath in commit 9ace29f for consistent naming with other methods in the class.

Re-raising with raise type(e)(...) drops important exception details (e.g., FileNotFoundError's errno/filename) and loses the original traceback context. Prefer raising with explicit exception construction per type and chaining with from e so callers keep the original context and error metadata.

Suggested change

	raise type(e)(f"Failed to load image from '{file_path}': {e}")
	if isinstance(e, FileNotFoundError):
	# Preserve errno and filename while adding context, and keep traceback via exception chaining.
	message = f"Failed to load image from '{file_path}': {e.strerror}"
	raise FileNotFoundError(e.errno, message, e.filename) from e
	else:
	# Preserve the original exception type and chain to keep traceback.
	raise pygame.error(f"Failed to load image from '{file_path}': {e}") from e

[Copilot]

Updated exception handling to use from e for proper exception chaining in commit 9ace29f. This preserves the original traceback context while providing descriptive error messages.
