You can insert images into
A vector image comprises geometric elements such as lines, points, and curves, based on mathematical equations. On the other hand, raster graphics are made up of pixels. A vector image is ideal for print-based output because the clarity is maintained even when you reduce the size of the graphic.
It is sometimes difficult to tell the difference between a vector and raster graphic when viewing it at 100%. But if you zoom in the difference becomes apparent. Following is an example of a PDF document with the same image in JPEG and SVG format.
The text in the SVG image is a little more readable. And if we zoom in, we can see why.
Here is what the JPEG image looks like when we zoom in at 300%. Notice that the pixels look blurry when enlarged.
And here is what the SVG image looks like. Notice that the text still looks as clear as it does at a much smaller size.
You can insert pages from PDFs as images. When you select a PDF file, you can choose the specific page from it to be inserted as an image.
PDF images are supported in all outputs. However, the way these files are treated depends on the output format:
PDF If you generate PDF output, the page you inserted is kept as a PDF. So it's sort of like a one-page PDF within a big PDF. You'll find that you can select text in that PDF image, just like you can in the larger PDF.
Also, any vector-based information is retained, therefore retaining the quality and clarity you expect. This is especially useful if you inserted a PDF that contains Microsoft Visio diagrams or vector drawings from CAD (computer-aided design) software.
All Other Outputs If you generate any output other than PDF, the PDF page you inserted is converted to a PNG file, even if it contains vector-based drawings. That's largely due to the fact that browser-based output types do not support vector images. Because the image displays in a raster format, you will find that it is not as crisp as its vector counterpart in PDF output.
You can accomplish the following with images.
- Images (Insert) These steps show you how to insert an image file that already exists. See Inserting Images.
- Screen Capture (Insert) Follow these steps if you have MadCap Capture installed on your computer and you want to capture an image from your screen and insert it into a topic at the same time. See Inserting Screen Capture Images.
- Background (Add) Read more… You can add background settings to an image. This includes the ability to specify a color, another image, and a repeating pattern for the background image. Normally you would not see an image's background, but if you give the image a certain amount of padding, you would see the background around the edges of it. See Adding Backgrounds to Images.
- Borders (Add) Read more… You can add borders around an image, specifying the border size, color, and type. See Adding Borders to Images.
- Image (Move) Read more… After you insert a picture or screen capture image into a content file, you can easily move that image around. See Moving Images in Content Files.
- Image (Resize) Read more… You can resize images with various methods. See Resizing Images.
- Margins (Add) Read more… You can adjust the margins around an image so that there is extra space above, below, to the right, or to the left of it. See Adding Margins to Images.
- Padding (Add) Read more… You can add padding (i.e., extra space) between an image's border and the image itself. See Adding Padding to Images.
- Position Read more… You can position an image so that content wraps around it. See About Positioning Elements.
- Thumbnails (Preview) Read more… In the XML Editor, when you are viewing a topic or snippet that contains a thumbnail image, you can right-click on that thumbnail and select Preview Image from the context menu. This enlarges the thumbnail image within the editor so that you can more easily see it and read any callouts within it. You can then click on the full-size image to return it to a thumbnail. See Previewing Thumbnails.
- Thumbnails (Show While Editing) Read more… You can specify that thumbnail images should be shown while you are editing the content. This is simply a feature for you as the author, allowing you to scale all images down to 48 pixels high (if the original size is larger than that). This lets you see more content and less of your images as you edit topics. The images are only scaled for your editing purposes; they are not
necessarilyshown as thumbnails in the output. See Showing Images as Thumbnails While Editing.
- Delete Read more… These steps show you how to delete an image that you have previously inserted into a topic. See Deleting Images from Content Files
- Hyperlink and Image Map (Insert) Read more… After you insert an image, you can turn that picture into a hyperlink. See Inserting Image Hyperlinks. You can also create multiple hyperlinks for specific sections of the image, and even place conditions on those sections. This is called an "image map." See Creating Image Maps.
- Image Frame (Add) Read more… You can draw an image frame in a page layout. The image you select is added to a frame of the same size, which you can place on the page as necessary. This allows you to place an image automatically on multiple pages in the output. You might use this feature, for example, if you want to place your company logo somewhere on each page. See Adding Images to Page Layout Frames.
- Select Read more… To select an image in the XML Editor, you can left-click on it. Another option is to right-click on it and choose Select from the context menu.
