Image Tool Settings
Use the Image settings window to select new images to insert, and set the default size, resolution, transparency and storage format of image objects.
The Image tool settings window contains a preview of the image and several sections that show the current values and parameters.

Preview and Image Info
This area allows you to choose an image to insert or replace, and shows a preview of the image at the current transparency.
When no image is currently selected, the Preview area shows an Open Image button. Press that button to open a pop-up dialog from which you can select one of the images already inserted in the project, a recently-opened image, or choose an image file from your computer.

When an image object is selected in the drawing, you can replace the image by pressing the Replace Image button that appears when you move the pointer over the preview. Replaced images preserve size, resolution and transparency of the previous image.
Press the Info button to view details and information about the image and its original file. The information include the location of the image file, its file size and modification date, and its bitmap size in pixels.
Size and Resolution
Use the width, height and resolution fields to resize the image. To constrain a proportional resizing, press the constrain proportions button, and open the units pop-up menu to select the preferred units.
Images can be displayed at their print resolution or at screen resolution. Use the Display at screen resolution switch to change this parameter. The visible size of the image is larger at lower resolutions.
To restore the original dimensions of the selected image after it has been resized, push the Restore Original Values button.
Transparency
Images can be displayed at variable transparency, ranging from 0% (fully visible) to 100% (fully transparent). This setting does not modify the image and can be adjusted at any time.
Storage Format
Images are handled like other vector objects and saved in the project file. The internal format can either be PNG, which preserves the full quality of the image, or JPEG, which compresses the image and saves file size considerably, but reduces the quality. JPG is very good for photographic images, but not for images that contain line drawings, such as city maps or scanned drawings.
