The promised day has come. We're finally going to be loading images from bitmap files into memory and drawing them as sprites on the screen. This is where all that stuff we've been learning--data types, pointers, memory management, file access, etc.--is going to pay off bigtime. Also, get fukt massive PutPixel sprite functions; die in a garbage fire.

Topics Covered
-
Surfaceclass for storing image data in memory - Parsing Windows bitmap file headers and loading pixel data
- Calculating padding
- Drawing sprites (pixel blocks) from a
Surfaceto the screen
Notes
We definitely should be checking for self assignment (mySurf = mySurf;) in the assignment operator for Surface. See Intermediate C++ Game Programming Tutorial 6#Errata for more details.

Homework
The homework is to improve the bitmap loading routine to support 32-bit RGB format and to support bitmaps with reverse row order.
