# Differences

This section is a brief discussion of the differences between the Windows and RISC OS versions of the program.

The Edit menu has Copy and Paste entries which will copy the current image to the clipboard or paste the clipboard contents into the current window. On Windows pressing the Print key copies the current screen to the clipboard, so Print followed by Paste is a quick way to do a screen snapshot.

Accuracy of colour matching is improved.

Alias filters are now given more comprehensible names.

Alias filters now apply to rotate and skew as well as scale.

Choices for filetypes no longer have "Double click run", instead the choices windows have an associate icon. This lets you tell Windows to associate a given file extension with DPScan. Association makes DPScan load files when they are double clicked, it also makes Windows display an icon from inside DPScan for files with the relevant extension. Turning off association will not return the association to the previous setting. To do that you will have to use the facilities in Windows (Windows explorer View->Options) or in the program you wish the file extension to be associated with. As well as the normal extensions like .tif for TIFF files, hexadecimal extensions are supported (ff0 for TIFF files), these are what you may end up with when you transfer a file from RISC OS or may let you resolve any clash of extension names with other programs.

A new supported filetype is Windows Cursor .cur, these are just .ico files with a different extension.

In Memory choices the temporary file path is;

<%TEMP%>

This means use the value of the Windows system variable TEMP. Other Windows system variables can be used when bracketed by %'s. It is also possible to insert the name of a Windows registry variable between < >'s.

Windows has a virtual memory system built in, I'd recommend setting DPScan Memory Choices Max RAM to a large value so that DPScan does not use its own virtual memory.

The Print window has been replaced with standard Windows Print and Print Page Setup windows (File menu).

Various menu entries have been moved around and some windows redesigned, however the Windows version of the program does at least as much as the RISC OS version, so if you can't find a feature at first, look around.
