# squarezoom

Zoom in and out of a neat little random square world.

![Screenshot](screenshot.png)

Requires [Futhark](http://futhark-lang.org) and SDL2 and SDL2-ttf

libraries with associated header files.

## Building and running

First run `futhark pkg sync` once.

## Controls

  - Mouse wheel scroll: Zoom in/out.

  - Left click and hold: Move around.

  - Right click: Automatic zoom.

  - Right click and mouse wheel scroll: Adjust automatic zoom speed.

  - `ESC`: Exit the program.

  - `F1`: Toggle the text in the upper-left corner.

  - `h`: View in the HSV color space (default).

  - `o`: View in the Oklab color space.

  - `g`: View as grayscale.

  - `r`: Generate a new world.

## `squarezoom-random`

Run `make && ./squarezoom-random/squarezoom-random -R -w 1024 -h 1024`

(or other powers of two) to build and run in a window.

## `squarezoom-image`

Run `make && ./squarezoom-image/squarezoom-image -R image.jpg

(or other powers of two) to build and run in a window.

To build without the FreeImage dependency, instead run

`SQUAREZOOM_NO_FREEIMAGE=1 make`.  This means you will only be able to

read and write images in the Netpbm PAM format.  You can use

ImageMagick's `convert` utility to convert from and to this format.
