3.2.8 Bitmap

To create a bitmap element:
1)Choose Symbol | Import Bitmap... from the Symbol Editor menu bar.
2)Choose the graphic file to be imported from the file dialog that opens and press Open. File types that can be imported are Windows bitmap (.bmp), GIF (.gif), JPEG (.jpg) and PNG (.png).

The imported bitmap element will appear in the drawing area. There are few editable properties for bitmaps: their Format Dialog contains only the Postion and Size and Condition tabs. For more information about these options, please see Section 3.2.1.

When using bitmaps it is important to remember that they take much longer to display than normal vector-based elements. Therefore, we advise you to consider carefully their use in symbols that are expected to be used extensively in diagrams. The main factor affecting performance is the number of pixels occupied on the screen by the resulting bitmap. Also, even though the Symbol Editor provides the means to scale the bitmaps, it is recommended that you try to import the pictures at the size they are projected to appear within the symbol. For a given on-screen size, the best performance is obtained when there is no overall scaling of the bitmap, taking into account the scaling of the symbol element, the scaling of the non-property representation in the diagram, and the current zoom factor of the Diagram Editor. While working with bitmaps in the Symbol Editor, setting the zoom factor to 100% will improve performance.
