BitBltLike

BitBltLike is a term used to describe functions or operations that mimic the behavior of the BitBlt (Bitmap Block Transfer) function found in graphics systems, particularly in Microsoft Windows. BitBlt is a low-level function that allows for efficient copying and manipulation of rectangular blocks of pixels from one memory location to another. This can include source bitmaps, destination bitmaps, or video memory.

Functions described as "BitBltLike" generally perform a similar pixel-by-pixel transfer. They are often used in graphics rendering, image processing, and window management to move or composite graphical elements. While the original BitBlt function offers various raster operations (ROPs) for combining source and destination pixels in specific ways, BitBltLike functions might implement a subset of these ROPs or a simplified copying mechanism.

The term is not a formal programming language keyword or standard API name but rather a descriptive phrase. Developers might use it to categorize functions that share the core functionality of BitBlt, even if they are implemented in different programming languages, libraries, or operating systems. This can include operations for screen capture, drawing elements onto a canvas, or implementing custom visual effects that involve pixel manipulation. The efficiency of BitBltLike operations is crucial for real-time graphics performance.
