About formats

PPTM is a macro-enabled presentation format for Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. Structurally identical to PPTX — a ZIP archive containing XML parts for slides, layouts, themes, and media — PPTM adds the ability to store and execute VBA (Visual Basic for Applications) macro code within the presentation. The deliberate separation of macro-enabled (.pptm) and macro-free (.pptx) extensions was a security design decision: users and administrators can identify macro-containing files by extension alone, and security policies can block or warn about macro-enabled formats while freely allowing standard PPTX files. PPTM files store VBA projects in a dedicated binary stream (vbaProject.bin) within the ZIP package, alongside the same XML slide content used by PPTX. Macros in PowerPoint presentations power automated slide generation, custom ribbon interfaces, interactive quizzes, data-driven content updates, and integration with external data sources. One advantage is workflow automation — PPTM enables repeatable processes like generating monthly report decks from database queries or updating financial charts across dozens of slides with a single button click. The format preserves full compatibility with the OOXML specification, meaning all standard PowerPoint features — transitions, animations, embedded media, SmartArt — work identically to PPTX. PPTM is supported by Microsoft PowerPoint on Windows and macOS, with macro execution limited to the desktop application.

Initial release: January 30, 2007
RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.

Frequently Asked Questions

Why convert PPTM to RGB?

RGB format stores raw color channel data with up to 255 gradations per primary color — supporting over 16 million colors. It is the native image format for SGI workstations and professional rendering environments.

What opens RGB files?

SGI workstation software, ImageMagick, GIMP, Photoshop, and XnView all handle the SGI RGB format. It integrates well with professional graphics and 3D rendering pipelines.

Is RGB compressed?

RGB files can be stored uncompressed or with RLE compression depending on the implementation. Uncompressed RGB preserves the raw sample data for maximum processing flexibility.

Does the conversion remove VBA macros?

Yes — RGB is purely a pixel data format. There is no mechanism for macros, scripts, or embedded code of any kind in the output.

How deep is the color representation?

Each of the three channels (red, green, blue) supports up to 255 gradations, yielding a total palette of 16,777,216 colors and up to 48-bit color depth.

Is PPTM to RGB free?
