The video tutorial explains how to manage bitmap loading by clearing buffers and handling files. It simulates loading time using delays and demonstrates displaying a bitmap from a text file. The tutorial introduces the concept of using a virtual proxy to load bitmaps on demand, optimizing memory usage and performance.

What is the first step when loading a new bitmap?

• Render the bitmap immediately

• Throw an exception if the file is missing

• Clear the buffer of the existing bitmap

• Display the current bitmap

Why is a delay used during the bitmap loading process?

• To check for file existence

• To ensure the file is not corrupted

• To simulate a long loading time

• To prevent memory overflow

What must be done before running the bitmap display?

• Set the bitmap as the default project

• Compile the bitmap class

• Copy the text file to the project directory

• Create a new bitmap instance

What is the purpose of using a proxy in bitmap loading?

• To enhance the bitmap quality

• To reduce the file size

• To load the bitmap only when display is called

• To load the bitmap faster

What type of proxy is used to load the bitmap on demand?

• Smart proxy

• Remote proxy

• Protection proxy

• Virtual proxy
