Rasterization at a fixed canvas: how WMF becomes BMP

The paths and shapes in WMF are rasterized onto a fixed pixel grid, then that canvas is encoded as BMP. Scaling the derivative later cannot recover the original curves. WMF input replays legacy GDI records with device-dependent mapping, font selection, clipping, pen and brush state, and integer coordinates onto the destination canvas. The BMP writer commits one rectangular pixel surface with explicit row order and color depth; it is aimed at simple bitmap interchange, not layered or multi-resolution artwork.

Source material - A legacy Windows Metafile storing GDI drawing records with limited modern graphics capabilities. Rendered deliverable - A plainly structured bitmap with minimal compression that most software can read.

INPUT MODEL

WMF

WMF vector graphic

Used for resolution-independent line art and technical drawings.

Family: Vectors
MIME: image/x-wmf

OUTPUT MODEL

BMP

BMP raster image

Designed for pixel-based artwork, scans, and photographs.

Family: Images
MIME: image/bmp

The delivery decision for this WMF to BMP route

BMP is right once the destination genuinely needs pixels. Logos, diagrams, or print work that must stay resolution independent still belong in WMF.

What changes between the WMF model and the BMP deliverable

Scalable WMF paths become a fixed-resolution BMP pixel grid; choose dimensions before delivery.
Metadata handling differs between WMF and BMP; do not assume every application-specific field carries across untouched.

Acceptance evidence for the converted BMP

BEFORE

Record the WMF evidence before conversion

Render at multiple sizes and inspect bounding box, line widths, text metrics, clipping, fills, colors, and orientation.

AFTER

Test the BMP file in its receiving workflow

Check the dimensions, color depth, and orientation, and confirm whether the app you're using actually reads BMP transparency.

WMF source facts versus BMP output requirements

WMF

What can fail when WMF vector graphic is interpreted

Coordinate precision, fonts, clipping, color, and device-dependent records can render differently outside Windows.

BMP

What BMP raster image cannot safely promise

A BMP derivative is typically far larger than a web-oriented image, and row order or alpha handling can differ between the apps that read it.

ENGINE

How the BMP writer handles this route

The writer builds a plainly structured bitmap with minimal compression that most software can read and labels the result as image/bmp. The receiving application - Not the extension alone - Is the final compatibility test.
