Resizing images and other elements
You can visually resize elements such as images, plugins, Macromedia Shockwave
or Flash movies, applets, and ActiveX controls in the Dreamweaver Document
window. Visual resizing helps you determine how an element affects the layout at
different dimensions.
Resizing resets the
width
and
height
attributes of the element. The W and H
fields in the Property inspector display the current width and height of the
element as you resize it. The element’s file size does not change.
Macromedia Flash movies and other vector-based elements are scalable and do not
lose quality as you resize them. However, bitmap elements such as GIF, JPEG, and
PNG images may become pixelated or distorted if you increase or decrease their
width
and
height
attributes. To maintain the same aspect ratio, hold down the
Shift key while you resize a bitmap. However, it is recommended that you visually
resize bitmaps in Dreamweaver only to determine the layout. Once you have
determined the ideal size for your image, edit the file in an image-editing
application. Editing the image may also reduce its file size and thus reduce
download time.
To resize an element:
1
Select the element (for example, an image or Shockwave movie) in the
Document window.
Resize handles appear at the bottom and right sides of the element and in the
bottom right corner. If resize handles don’t appear, either click away from the
element you want to resize and then reselect it, or click
<img>
in the tag
selector to select the element.
2
Resize the element by doing one of the following:
•
To adjust the width of the element, drag the selection handle on the right side.
•
To adjust the height of the element, drag the bottom selection handle.
•
To adjust the width and the height of the element at the same time, drag the
corner selection handle.
•
To preserve the element’s proportions (its width-to-height ratio) as you adjust
its dimensions, Shift-drag the corner selection handle.
Elements can be visually resized to a minimum of 8 x 8 pixels. To adjust the width
and height of an element to a smaller size (for example, 1 x 1 pixel), use the
Property inspector to enter a numeric value.
To return a resized element to its original dimensions, in the Property inspector,
delete the values in the W and H fields, or click the Resize Size button.
