# xzoom(1)

magnify part of X display, with real-time updates

## NAME

**xzoom** - magnify part of X display, with real-time updates

## SYNOPSIS

```
xzoom
xzoom [args]
xzoom [-x ] [-y ] [-mag magnification]
      [-geometry 'width size' x 'height size']
```

## DESCRIPTION

**Xzoom displays in its window a magnified area of the X11 display. The user** **can interactively change the zoomed area, the window size,** *magnification* **(optionally different** *magnification* **for X and Y axes) or rotate or mirror** **the image.**

**Use commands to change rotation, zoom or mirror the image.**

## OPTIONS

- **-d \<displayname\>, -display \<displayname\>**

  **The name of the display to use.**

- **-mag \<*magnification* \[ *magnification* \]\>**

  **What** *magnification* **to use. If two** **number arguments are supplied the first is used for X magnications and the** **second is used for Y** *magnification***. Magnification should be greater than 0.**

- **-geometry \<geometry\>**

  **Size and position xzoom's window.**

- **-source \<geometry\>**

  **Size and position the initial source area which is** **magnified. The dimensions of this area are multiplied by the** *magnification* **to get the size of xzoom's window. If these dimensions are given separately** **(by use of -geometry) then an error is reported.**

- **-*x***

  **Mirror horizontally.**

- **-y**

  **Mirror vertically.**

- **-xy**

  **Exchange X and Y axes before any** *magnification* **is performed.**

## COMMANDS

- **+**

  **Increase** *magnification* **value by 1.**

- **-**

  **Decrease** *magnification* **value by 1.**

- ***x***

  **Mirror the display image horizontally.**

- **y**

  **Mirror the display image vertically.**

- **z**

  **Rotate 90 degrees counter-clockwise.**

- **w**

  **Next '+' or '-' only change width scaling.**

- **h**

  **Next '+' or '-' only change height scaling.**

- **d**

  **Sets the delay between frame updates. Built-in delays are 200, 100, 50,** **10 and 0 ms.**

- **q**

  **Quit.**

- **Arrow keys**

  **Scroll the zoomed area 1 pixel in the direction of the arrow.** **if the control key is pressed the zoomed area will scroll 10** **pixels.**

- **Mouse buttons**

  **To set the location of the magnified area, click the left mouse** **button inside xzoom's window and then move it (keep the button** **pressed) to the place which you want to see magnified.**

**Xzoom allow you to resize it's window at any time.**

**When xzoom is iconified it simply waits to get deiconified.**

## EXAMPLES

- **xzoom -mag 5**

  **# Open xzoom with** *magnification* **5.**

- **xzoom -mag 2 -geometry 800x400**

  **# Open xzoom with** *magnification* **2 and windows size 800x400.**

- **xzoom -*x***

  **# Open display flipping right and left.**
