# DPlngScan

### Introduction

DPlngScan is a program for manipulating bit map images.

The special features of the program are;

- The ability to handle images bigger than memory, by using disc space. So called "virtual memory".
- The program can work with 1, 2, 4, 8, 16, 24 and 32 bits per pixel images. Many programs are limited to just one value.
- Images may be manipulated even if the display hardware does not support them. For example 24 bit pictures can be loaded, manipulated and resaved as 24 bit images. Real time dithering is used to display the image in screen modes with smaller numbers of bits per pixel.
- TWAIN. Supports this general interface to scanners.

### Installation

If you are using DPlngScan with a scanner, you will need to install TWAIN on your hard disc. You will also have to have some sort of physical connection between the scanner and the computer. Full details of this are given in the TWAIN manual.

DPlngScan can be installed on your hard disc by dragging the !DPlngScan directory to the desired destination.

DPlngScan is run by double clicking on the !DPlngScan icon in a filer window, it will then install on the icon bar.

DPlngScan should run on all versions of RISC OS from 3.10 onwards, and should also run on a range of non-native hardware under emulation. One requirement is that the SharedCLibrary must be at least version 5.34.
