If you are creating images for use on the Internet or on the screen, you only need to use a resolution of 72 ppi (pixels per inch). You can open a large resolution image in Low Resolution mode to increase command speed. SmartSizing maintains the detail of an image by using aliasing when you change the size or resolution of the image. An Image Spray item is a Picture Publisher Format (PPF) file with floating objects. The Web Pattern Viewer lets you view an image as it would appear on an Internet web page as a tiled background pattern. You can preview a transparent GIF on a tiled background pattern using the Pattern View Options command. Press and hold the right mouse button and move the mouse to reposition a mask or selection rectangle while you are drawing it. A mask is a border used to set off an area for changes or protection from changes. Masks also mark an area for copying or cutting to the Windows Clipboard or a named clipboard. Picture Publisher displays a "ToolTip" when you rest the mouse pointer over an object. The ToolTip displays the name of the object (if any), the objec The Object Manager contains small image thumbnails for selecting or deselecting each object. Using the Object Manager, you can hide, group, delete selected objects. Double-click the Color Swatch on the Main toolbar to open the Color Picker dialog box. The Smart Mask tool draws a mask automatically based on color. You choose the color to be masked by pointing the cursor to an area of the image you want masked and clicking. An image's PPI (pixels per inch) is the measure of an image's resolution on the screen. An image's DPI (dots per inch) is the measure of an image's resolution on a printer. You can correct "washed out" images using the Tone Balance or Contrast/Brightness commands on the Map menu. You can select a texture by clicking the Texture button on the Texture tool and Texture Fill tool ribbons. You can remove the "red eye" effect common in many portrait images using the Red Eye Removal Wizard. You can rotate an object using either the Selector Transform tool or the Rotate command on the Object menu. Copy objects you use on a consistent basis to the ClipboardBrowser. The Drop Shadow command on the Object menu creates a drop shadow from any floating object or masked area. It is not always necessary to scan an image at an extremely high DPI. The quality of your output to your printer is limited to the lines per inch of the printer. Therefore, the final PPI of the image should be equal to two times the lines per inch of your printer's output. You can create common text effects, including neon, stamped and embossed text, using the CoolText Wizard. To remove part of a mask, click the Subtractive Mode button on the Mask tool ribbons. Use the Page Up and Page Down keys to zoom in and out of an image. You can drag an object from the Object Manager onto the Picture Publisher desktop. The Image Spray tool lets you paint with images instead of a color. You can choose from predefined collections of images included with PhotoMagic or you can create your own image collections. Floating objects in Picture Publisher are called "layers" or "selection areas" in other image editing applications. Click the Pure White or Pure Black buttons in the Color Picker dialog box to choose these colors instantly. You can only apply an Effect from the EffectsBrowser to RGB or grayscale images. The Opaque Overlay macro creates a transparent white overlay you can use to enhance text on an image. You can create a vignette by using either the Feather Mask command on the Mask menu, or applying a Gaussian Blur effect in the mask channel. You can use the Image Spray tool to create Web content, image borders, or to paint within text. Micrografx Picture Publisher is the leading "digital darkroom" for Windows 95 or Windows NT operating systems. You can only keep floating objects on a saved image if you save the file using the Picture Publisher Format (PPF). To nudge objects pixel by pixel, press and hold the Shift key and use the arrow keys.
