Using PicaView

The PicaView File Manager Menu

Once installed, PicaView will show up as an extra menu pop-up in File Manager.  This menu allows you to view and print the currently selected file in the file list, as well as get help and set options.

The PicaView Window

When an image is being viewed by PicaView, a separate window comes up to display the image.  By clicking the right mouse button inside this window, you can bring up a Pop-up menu similar to PicaView's menu in File Manager.  By double-clicking the left mouse button inside the window, PicaView will toggle between preview and full-image display.

To view an image

1)	Highlight an image in the File Manager file list

2)	Select "PicaView | View Full Image" from the File Manager menu.

To preview an image

1)	Highlight an image in the File Manager file list

2)	Select "PicaView | Preview" from the File Manager menu.

To automatically preview images as you select them

Check the "PicaView | Auto-Preview" menu option.

To quickly switch between preview and view modes

Double-click on the preview window.

To print an image

1)	Highlight an image in the File Manager file list

2)	Select "PicaView | Print...from the File Manager menu.

You can also configure PicaView to allow extra shortcuts for previewing images.  For example, you can have PicaView do nothing the first time you click on an image file (Auto-Preview off), show a preview the second time you click on an image file (Double-select to Preview), and close the preview window the third time you click on an image files (Select file again to close image)

Options

Preview Options

These options affect how the preview image is displayed.

Fit to window/screen	The image will be shrunk if necessary to fit within the bounds of the window.

Full size	The image will appear in full size.

1/2 size	The image will be shrunk to 1/2 of its normal size.

1/4 size	The image will be shrunk to 1/4 of its normal size.

1/8 size	The image will be shrunk to 1/8 of its normal size.

Auto-size to image	The size of the window will be changed to match the size of the image, within the dimensions of the screen.

Auto-activate	The window will be activated whenever an image is previewed or viewed.  This option should be checked when running in 256 colours in order for the palette to be handled correctly.

Always on top	The window will always appear above other windows, even when it is not activated.

View Options

These options affect how the image is displayed when the "View Full Image" command is used.

Window - Auto-size	The size of the window will be changed to match the size of the image, within the dimensions of the screen.

Window - Full-Screen	The window will appear full-screen (maximized, with no title-bar)

Shrink image to fit 	The image will be shrunk if necessary to fit within the bounds of the window.

Dither Options

These options affect how a truecolor image is displayed on a 256-colour or hicolor video display.

256 Colour Dither

Ordered	Use an ordered dither (fastest)

Floyd-Steinberg	Use a Floyd-Steinberg dither (slower but better appearance)

Hicolor Dither

None	Don't dither (fastest)

Ordered	Use an ordered dither (slightly slower but improves quality - eliminates banding effects, most noticable on computer generated images)

Interface Options

These options affect how PicaView's functionality is controlled via File Manager

Auto-Preview	A preview will be shown automatically whenever an image is selected in the File Manager file list

Auto-Preview Delay	Sets the delay between when an image is selected and when the automatic preview activates.

Double-select to preview image

Causes a preview to be shown when a file is clicked a second time with the mouse, or selected a second time with the spacebar (the second selection must occur 0.2 seconds or more after the first)

Select file again to close image

When this option is on and the selected image is being shown by PicaView, selecting the file again (clicking with the mouse or pressing the spacebar) will cause the image window to be closed

If you use PicaView beyond the 30 days, you should register it.  Registration entitles you to free upgrades to the software, which is nice.

How To Register

You may register by credit card over the phone or FAX, via Compuserve, or by money order.  In any case, the cost of registration is a modest $US 15.
