Info

Choosing a graphics mode You can change color images to grayscale by selecting the image and then selecting Grayscale from the Graphics mode list. Table 5: Graphics modes Graphics mode Behavior Default Keeps the picture the same as it was inserted. Grayscale Shows the picture in gradual shades of gray. Black / White Converts the picture into a monochromatic black and white image. Watermark Makes the picture into a watermark that blends into the background. Using graphic filters Click the Filter icon to display the Graphic Filter toolbar, which provides options for applying basic photographic and effect filters to images from within Calc. To “tear off” this toolbar and place it anywhere on the screen, click on the three parallel lines and drag it away. Table 6: Graphic filters and their effects Icon Name Behavior Invert Inverts the colors in the picture like a negative. Smooth Applies a Gaussian Blur to the image which softens edges. Sharpen Sharpens the image. Remove Noise Solarization Applies crude noise reduction. Reverses a portion of the tones, then produces pronounced outlines of the highlights. Aging Applies a Sepia filter. Posterize Opens a dialog to determine the number of poster colors. This effect is based on the reduction of the number of colors. It makes photos look like paintings. Pop Art Applies a Pop Art style to the image. Charcoal Sketch Relief Mosaic Applies a Charcoal Sketch look to the image. Displays a dialog for creating reliefs. The position of the imaginary light source that determines the type of shadow can be chosen. Joins small groups of pixels into rectangular areas of the same color. The larger the individual rectangles are, the fewer details the graphic image has. 130 LibreOffice 3.4 Calc Guide
Caution Adjusting colors Applying LibreOffice picture filters to any image consecutively will progressively degrade the quality of the image. The picture filters used in Calc utilize what is known as a Destructive Editing algorithm, whereby each filter is applied to the image immediately, changing the original data of the image. Successive transformations result in less and less original data remaining, thus compromising the quality of the inserted picture. While this might be acceptable for use in simple documents, it is still recommended that dedicated photo or image editing software be used to perform anything but the simplest of manipulations. Use the Color toolbar to adjust an image’s red, green, and blue channels independently, as well as its brightness, contrast and gamma. Setting transparency Modify the percentage value in the Transparency box on the Picture toolbar to make the image more transparent. This is particularly useful when creating a watermark or when wrapping an image in the background. Customizing lines, areas, and shadows The Line, Area, and Shadow icons open dialogs where you can customize these elements. Details are in the Draw Guide. Cropping pictures When you are only interested in a section of the image for the purpose of your document, you may wish to crop (hide) parts of it. If you wish to remove (delete) areas of the image it may be a better choice to use a graphics package. Click the Crop icon to open a dialog where you can select which portion of the image you want to remove from view. It is not possible to use the mouse to select the area to be cropped, as you can in Draw. Instead, in the Crop dialog, specify how far from the top, bottom, left and right borders of the image the crop should be, as illustrated in Figure 125. On the thumbnail in the figure, notice that the cropped selection is highlighted with an inner rectangle. On the Crop dialog, you can control the following parameters: Keep scale / Keep image size When Keep scale is selected (default), cropping the image does not change the scale of the picture. When Keep image size is selected, cropping enlarges (for positive cropping values), shrinks (for negative cropping values), or distorts of the image so that the image size remains constant. Left, Right, Top, and Bottom The image is cropped by the amount entered in these boxes. For example, a value of 3cm in the Left box cuts 3 cm from the left side of the picture. • When Keep scale is selected, the size of the image also changes, so in this example the width will be reduced by 3 cm.
