# img-tiff(3tk)

Tagged Image File Format (tiff)

```

```

## NAME

img-tiff - Tagged Image File Format (tiff)

## SYNOPSIS

package require **img::tiff ?2.0?**

```

```

## DESCRIPTION

**package require img::tiff**

Like all packages of **Img** it does *not* provide new commands, but extends the existing **Tk** command **image**, so that it supports files containing raster images in the Tagged Image File Format (tiff). More specifically **img::tiff** extends **Tk**'s *photo* \[https://www.tcl.tk/man/tcl9.0/TkCmd/photo.html\] image type.

The name of the new format handler is **tiff**. This handler provides new additional configuration options. See section **Options** for more detailed explanations.

All of the above means that in a call like **image** **create photo** ?*name*? ?*options*?

- \[1\]

  Image data in tiff format (options **-data** and **-file**) is detected automatically.

- \[2\]

  The format name **tiff** is recognized by the option **-format**.

In addition the value of option **-format** is treated as a list and may contain any of the special options listed in section **Options**.

The package **img::tiff** is a sub-package of **Img**. It can be loaded as a part of the complete Img support, via **package require Img**, or on its own, via **package require img::tiff**.

## NOTES

- \[1\]

  Chapter *Multi-page Images* of the **Img** manual page describes the handling of images with multiple pages.

- \[2\]

  Chapter *Image Metadata* of the **Img** manual page describes the parameters of the resolution related options.

  This option is supported for reading and writing. Available since version 2.0.

  If set to **true**, additional information about the read or written image is printed to stdout. Default is **false**.

- **-index** *integer*

  This option is supported for reading only. Available since version 1.4.0.

  Read the page at specified index. The first page is at index **0**. Default is **0**.
