Modify images

When you insert a new image, you may need to modify it to suit the document. Writer provides many tools for working with images like resizing, cropping and color changing. If your images need more complex editing then it's better to use an image manipulation software such as GIMP.

The Image Toolbar

When you insert an image or select one already present in the document, the Image toolbar appears. You can do most of the image editing tasks using this toolbar

Resizing

To resize an image simply drag with the mouse one of the green sizing handles. In this way the image is resized proportionally and keeps the original ratio between width and height.

To resize the width or height only hold down the shift button while dragging the green point

Cropping

When you are only interested in a section of the image for the purpose of your document, you may wish to crop (cut off) parts of it. To crop an image first click on the crop icon and then drag one of the red cropping handles points.

Flip and Rotation

You can flip and rotate an image using these buttons

Transparency

Modify the percentage value in the Transparency box on the Image toolbar to make the image more transparent. This is particularly useful when creating a watermark or when wrapping the image in the background.

Graphics mode

You can change color of an image to grayscale, to black and white, or to a
watermark by selecting the relevant menu item from the Graphics mode list.

Filters

An image filter is a technique to change the apperacnce of an image in a certain way. To apply an image filter in your document select one of the available by clicking on the filters  icon.

Colors

Use the Colors toolbar to modify the individual RGB color values of the image (red, green, blue) as well as the brightness, contrast, and gamma of the image. If the result is not satisfactory, you can press Control+Z to restore the default values. To open the colors toolbar click on the  icon
