Compatibility: AA:PR

  Description: Datatypes Picture Viewer
        Notes: Freeware

DTPicView is a picture viewer that solely relies on the datatypes library for
displaying bitmap images.


Features
--------

 - Progressive display. Watch the pictures as they are being loaded.
 - Multithreaded and multi-window. Load several pictures simultaneously.
 - Automatic dithering on 8-bit screens.
 - Bitmaps can be saved in any datatypes supported format.


Usage
-----

Drag one or more pictures onto DTPicView's icon to load them. Alternatively,
you can just start the program, and a file panel will appear. You can then
select the picture(s) that you want to view from there. You can also use
DTPicView from the command line. Type '--help' to see how to use it.

You can scroll around a DTPicView window by using either the mouse (scroll
bars) or the keyboard; use shift for large steps. Scrolling is even possible
when a picture is still loading. You may click the window close button to try
and abort the loading or saving of a picture. Also, you can drag and drop
files onto a DTPicView window to load them.

Click anywhere inside a DTPicView window, or press space or return on the
keyboard, to get DTPicView's pop-up menu. This menu will allow you to get
information on the picture, load more pictures, save a bitmap in any
datatypes suported format, or change DTPicView's settings. When the 'Ask
Handler for 8-bit' setting is enabled, DTPicView will ask the datatype
handler for an 8-bit bitmap. Some handlers, like JPEGHandler, have nicer
dithering then the internal dithering routine of DTPicView. The 'No
Dithering' setting disables automatic dithering on 8-bit screens by
DTPicView. This can come in handy when you want to load and save a bitmap in
its full 32-bit glory. Finally, the 'Use Media Stream' setting enables media
stream support in DTPicView. This allows you to see real progressive JPEGs,
and even QT movies.
