Cropping and editing bitmaps
After you add a bitmap to a drawing, you can crop, resample, and resize the bitmap. Cropping removes unwanted areas of a bitmap. To crop a bitmap into a rectangular shape, you can use the Crop tool. For more information, see “To crop objects.” To crop a bitmap into an irregular shape, you can use the Shape tool and the Crop bitmap command.
When you resample a bitmap, you can change the image or the resolution, or both, by adding or removing pixels. If you make an image larger without changing the resolution, the image may lose detail because the 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. Upsampling adds pixels to maintain some details from the original image.
