Image Support

LOADIMAGE Function

Load BMP images as shapes that can be moved, rotated, and scaled.

Usage

id$ = LOADIMAGE("filepath.bmp")

Parameters:

• filepath - Path to BMP image file (relative or absolute)

Returns:

• Shape ID string (use with MOVESHAPE, ROTATESHAPE, etc.)

Example

SCREEN 12, 640, 480, "Image Demo"

REM Load image
DIM sprite$
LET sprite$ = LOADIMAGE("player.bmp")

REM Position and transform
MOVESHAPE sprite$, 320, 240
ROTATESHAPE sprite$, 45
SCALESHAPE sprite$, 2.0

REM Draw
SCREENLOCK ON
CLS
DRAWSHAPE sprite$
SCREENLOCK OFF
SLEEP 3000
REM Cleanup when done
REMOVESHAPE sprite$

Image Transformations

Once loaded, images work exactly like other shapes:

DIM img$
LET img$ = LOADIMAGE("logo.bmp")

MOVESHAPE img$, x, y           ' Position
ROTATESHAPE img$, angle        ' Rotate (degrees)
SCALESHAPE img$, scale         ' Scale (1.0 = original size)
SHOWSHAPE img$                 ' Make visible
HIDESHAPE img$                 ' Make invisible
DRAWSHAPE img$                 ' Render to screen
REMOVESHAPE img$               ' Delete and free memory

Creating Test BMP

To create a test BMP for the demo:

Using Paint (Windows)

1. Open Paint
2. Create image (e.g., 64x64 pixels)
3. Draw something
4. File → Save As → BMP Picture
5. Save as "test.bmp" in your BazzBasic directory

Using GIMP

1. Create new image (64x64)
2. Draw content
3. File → Export As
4. Choose "Windows BMP image"
5. Save as "test.bmp"

Current Limitations

• BMP only: Currently only supports .BMP files (uncompressed)
• No transparency: BMP format doesn't support alpha channel
• Memory: Images consume more memory than primitive shapes
• Color depth: 24-bit BMP recommended

Future Enhancements

Planned:

• PNG support (with transparency)
• JPG support
• Sprite sheets
