# posterazor(1)

splits an image across multiple pages for assembly into a poster

## NAME

**posterazor** - splits an image across multiple pages for assembly into a poster

## SYNOPSIS

```
posterazor [ inputfile ]
```

## DESCRIPTION

**The PosteRazor splits an image to form a multi-page PDF document. When printed, the sheets can be arranged to form a large poster of the original image.**

**If no** *inputfile* **is specified as a command line argument, the user will be prompted for one.**

**Current Features:**

- **Input image formats**

  **All image formats that FreeImage can read should be usable as input for the PosteRazor:** **BMP, DDS, Dr. Halo, GIF, ICO, IFF, JBIG, JPEG/JIF, KOALA, LBM, Kodak PhotoCD, PCX, PBM, PGM, PNG, PPM, PhotoShop PSD, Sun RAS, TARGA, TIFF, WBMP, XBM, XPM.**

- **Color types**

  **PosteRazor can handle the following image color types:** **Monochrome, Grayscale, 4 Bit palette, 8 Bit palette, 24 Bit RGB, 48 Bit RGB (only via TIFF and PNG), 32 Bit CMYK (only via TIFF)** **32 Bit RGBA images can be loaded, but are transformed to 24 Bit RGB by "merging" them with a white background.**

- **Dimension units**

  **Because people around the world invented so many different dimension units, PosteRazor supports quite a few:** **m, mm, cm, inch, ft, pt(72th inch).**

- **Printer page layout**

  **The page size and orientation of the printer where the poster will be printed can be set manually or selected one from the following list of predefined formats:** **DIN A4, DIN A3, Legal, Letter or Tabloid.** **The size limit for one page is 5 meters (16.4 feet), which is the maximum that PDF allows.**

- **Poster size**

  **The size of the final poster can be set through one of these three ways:**

  - **- Absolute image size**

    **You want to have a specific size of your poster.**

  - **- Size in Pages**

    **You want to use whole paper sheets and specify how many of them of them you want to use.**

  - **- Image Size in percent**

    **Your input image has a certain size which is defined by the number of pixels and dpi (dots per inch) and your want to scale the image by a certain factor.**

  **The final size of the poster is theoretically unlimited. Let's say it this way: it is less limited that the ink of your printer.** **It is possible to select the alignment of the image on the total paper. This is useful if you want to keep the unused paper.**

- **Image tile overlapping**

  **For a bigger tolerance when cutting spare paper borders and for easier pasting, an overlapping width and height of an image** **tile over the next can be set.**

- **PDF output**

  **The PDF output is implemented with the maximum image quality and a good compression in mind.** **A source image is embedded once in the PDF document and referenced from every tile page. Image color types remain unchanged.** **As compression method, the PDF "FlateDecode filter" (zip) is used. If a JPEG image is used as input it gets directly embedded into the document without recompression.** **The PDF version is 1.4, so any compatible reader should be able to read the resulting document.**

**Missing Support:**

- •

  **Cut lines/aids;**

- •

  **Support of JPEG-CMYK images;**

- •

  **Support of 16 Bit Grayscale images;**

- •

  **Embedding an ICC profile into the PDF if there is one embedded in the input image.**
