Throughout LibreOffice, frames are usually less trouble if you follow these best practices: Experiment with image size, making it no larger than necessary for legibility.See if you can improve the contrast of an exceptionally dark or light image.Crop any blank space in an image if possible.Check for details in the background that might accidentally violate someone’s privacy.If you take a screen shot of a menu, white out any irrelevant text and dialogs in the background.Cleaning Up the ImageĪs a final step in image editing, remove any unnecessary clutter. Include the shadow and you have a natural border that needs no further attention. If possible, crop the image so that all its edges are a different color from the document’s background.įor example, some operating system or desktop themes place a shadow around dialog windows. However, a natural border can be just as effective. You can add a border to an image in LibreOffice. Indicators call attention to elements that you want readers to find easily as they follow your discussion. Leave some context so readers can locate what you are discussing. Some writers put jagged edges around a cropped image, as though it were torn from a page, which is a vivid effort, but a time-consuming one. You have two main choices: cropping or adding indicators.Ĭropping is the reduction of the image to whatever is essential. Using Cropping or IndicatorsĮditing a graphic helps readers know what to focus on. If you are making original graphics, one solution is to make everything three times the size you need, then reduce it so that it is the right size at 3oo DPI. Most editors work at the screen display of 72 DPI. Most images can be enlarged by 50 percent, but few can be increased to 200 percent without becoming badly distorted unless they are very simple. Getting the highest resolution is a tradeoff: the higher the resolution, the smaller the actual or printed size of the image. Many graphic editors will show an actual size and a printed size, displaying each in a number of different formats, including pixels, points, inches, and percentage. Resolution is best set in a graphics editor. For a hard copy, use a minimum of 300 DPI, or 600 DPI or higher for quality printing. Deciding to crop the image or to add indicators to point to features.įor an online document, a resolution of 72 DPI (dots per inch) is usually enough.Setting the image’s resolution and print size. ![]() However, the four operations necessary for every image are: Graphics editors allow you to change the size and colors of an image and do many other operations besides. If the image is already open, right-click to copy it, then paste it in a new file in the graphics editor. ![]() You can open images in other applications by right-clicking and selecting EDIT WITH EXTERNAL TOOL, or directly from the graphics editor. If some images are too large to display legibly at this size, consider adding a landscape page style for them. ![]() You will need this measurement when sizing images. You can determine this distance by subtracting the vertical margins from the page width given on the PAGE tab of each page style. Editors such as GIMP and Krita are free to download for all the operating systems that LibreOffice runs on.īefore editing images, measure the distance between the left and right (or inner and outer) margins on all pages where images might display. Graphics editors can be a more versatile and reliable way of preparing images than the tools that LibreOffice itself provides. The following is an excerpt from TNS author Bruce Byfield‘s newly published book “ Designing with LibreOffice,” which is all about getting the most from the LibreOffice open source office document suite.
