Cropping and editing bitmaps

After you add a bitmap to a drawing, you can crop, resample, resize, and inflate the

Cropping removes unwanted areas of a bitmap. When you resample a bitmap, you can change the image size, the resolution, or both by adding or removing pixels. For example, if you make an image larger without resampling, you can lose details because the image's pixels are spread over a greater area. By resampling, you can add pixels to preserve more detail from the original image. Resizing an image maintains the same number of pixels in a smaller or larger area. For example, you can lose details when you make an image larger without resampling, because the image's pixels are spread over a greater area. Upsampling adds pixels to maintain some of the original's details.

image.

With resampling, you can either increase the resolution of an image by adding pixels (upsampling) or decrease the resolution by subtracting pixels (downsampling).

To crop a bitmap

1 Open the Shape flyout, and click the Shape tool it .

2 Select a bitmap.

3 Drag the bitmap's corner nodes to the shape you want.

If you want to add a node, double-click the node boundary by using the Shape tool where you want the node to display.

4 Click Bitmaps ► Crop bitmap.

You cannot crop a bitmap comprised of more than one object.

i^s You can also crop a selected bitmap after you drag the bitmap's corner nodes by clicking the Crop bitmap button on the property bar.

To resample a bitmap

1 Select a bitmap.

2 Click Bitmaps ► Resample.

3 In the Resolution area, type values in any of the following boxes:

• Horizontal

If you want to maintain the proportions of the bitmap, enable the Maintain aspect ratio check box.

If you want to maintain the file size, enable the Maintain original size check box.

j^s You can also resample a selected bitmap by clicking the Resample button on the property bar.

Enable the Anti-alias check box to minimize the jagged appearance of curves.

To resize a bitmap

1 Select a bitmap.

2 Click Bitmaps ► Resample.

3 Choose a unit of measure from the list box beside the Width and Height boxes.

4 Type values in any of the following boxes: • Width

If you want to minimize the jagged appearance of curves, enable the Anti-alias check box.

You can maintain the proportions of the bitmap by enabling the Maintain aspect ratio check box and typing a value in either the Width or Height box.

You can also resample the bitmap as a percentage of its original size by typing values in the % boxes.
