You can add images to your topics to support your content and enhance your online information. You can even use these images as links (hotspots) to other topics. In a topic, images are part of the text that make up a topic and they flow with the text as you add and delete information. You insert images into your topics in the WYSIWYG Editor.
The following image formats can be included in your projects:
GIF (Graphic Interchange Format): An 8-bit color format that can display up to 256 colors and is generally useful for non-photographic images with a somewhat limited range of color, such as a screen shot of a dialog in your application. GIFs support the transparent attribute where parts of the image appear to be floating over the topic. GIF images provide the best quality for grayscale photographs, cartoons, small icons, buttons, bars, lines, and bullets. GIF images can be interlaced, where the HTML topic slowly builds an image of the GIF in gradual steps. GIFs can also be animated where multiple layers are stored in a single file and are played sequentially to create an animation.
JPEG, JPG (Joint Photographic Expert Group format): Compressed high-color or true-color images. If you are using images with 256 colors or more, you will want your images to be in compressed JPEG format which is handled very well by HTML browsers and by the HTML Help viewer.
BMP (Windows Bitmap - imported): The standard bitmap image format intended for Windows systems (commonly used in WinHelp applications). Bitmap images support up to 24-bit color. When you import WinHelp projects into HTML, the bitmaps are converted into .GIF or .JPG formats (depending on the option you specify). You can use bitmaps and icon formats (.ICO files) when you add link controls or HTML Help controls (custom buttons).
MRB (Multi-Resolution Bitmap - imported): A Windows Help-specific image format that contains an image (such as a screen shot) saved in different screen resolutions packed into a single file. The program imports these files from WinHelp projects and converts them into .GIF images.
WMF (Windows Metafile - imported): A vector graphics format (a collection of geometric shapes rather than pixels) intended for Windows systems. WMF files are commonly used as clipart for word processing applications. The program imports these files from WinHelp projects and converts them into .GIF images.
Note: If you want to give your topics a paper stationery look, you can define them to display different background colors and images from the Borders and Shading dialog.
