About formats

EMF (Enhanced Metafile) is a vector graphics format developed by Microsoft as the successor to WMF (Windows Metafile), introduced with Windows NT 3.1 in July 1993. EMF records a sequence of GDI (Graphics Device Interface) function calls that describe vector shapes, text, embedded bitmaps, and rendering attributes in a device-independent manner. Unlike WMF's 16-bit coordinate system limited to 65,536 units, EMF uses 32-bit coordinates and adds support for Bezier curves, advanced path operations, world coordinate transforms, gradient fills, and extended text capabilities including Unicode. The format functions as a graphics recording mechanism — applications capture their drawing operations into an EMF file, which can then be replayed at any scale on any device with full geometric precision. One advantage is native Windows integration: EMF is the standard clipboard and spooler format for vector content across the Windows ecosystem, enabling lossless copy-paste of graphics between Office documents, design tools, and presentation software without rasterization. Resolution independence is another key strength — EMF graphics scale smoothly from screen display to high-resolution print output. An extended variant, EMF+, introduced with GDI+ adds anti-aliasing, alpha transparency, and advanced brush types. EMF remains deeply embedded in Windows-based publishing, technical documentation, and enterprise document workflows.

PFM (Portable Float Map) is a floating-point raster image format devised by Paul Debevec around 2001, designed to store high-dynamic-range image data with the simplicity of the Netpbm family of formats. PFM extends the PBM/PGM/PPM philosophy — minimal header, raw data, no compression — to 32-bit IEEE floating-point samples, providing direct access to HDR pixel values without the encoding overhead of formats like OpenEXR or the limited range of Radiance HDR's RGBE encoding. The file structure is deliberately minimal: a two-character magic number ('Pf' for grayscale, 'PF' for color), width and height on the next line, a scale/endianness indicator (negative for little-endian, positive for big-endian, with magnitude indicating scale factor), and then the raw 32-bit float data for each pixel. PFM files store one float per pixel for grayscale or three floats (RGB) per pixel for color, with no compression, alpha channel, or metadata support. The format emerged from the HDR imaging research community where Debevec's work on image-based lighting and light stage capture required a simple, unambiguous way to store linear floating-point radiance values that could be easily exchanged between research tools. One advantage is absolute simplicity for HDR data: PFM can be read and written in a few lines of code in any language that supports IEEE floats, with no library dependencies — ideal for research prototyping and quick data exchange between custom tools. The format's widespread adoption in the computer vision and computational photography research community is another practical strength — optical flow benchmarks (Middlebury), depth estimation datasets, and radiance field captures commonly use PFM. The format is supported by ImageMagick, OpenCV, HDR Shop, and Luminance HDR.
