Syntax
Bitmap ( string )
|
Argument |
Description |
|---|---|
|
string |
A column containing the image files, a string containing the name or URL of an image file (a BMP, GIF, JPEG, RLE, or WMF file), or an expression that evaluates to a string containing the name or URL of an image file |
Return value
The special datatype bitmap, which cannot be used in any other function.
Usage
Use Bitmap to dynamically display an image file in a computed field. When string is a column containing image files, a different image can display for each row.
Examples
These examples are all expressions for a computed field.
This expression dynamically displays the image file contained in the column named employees:
Bitmap(employees)
If the employees column is column 3, this next expression gives the same result as the expression above:
Bitmap(#3)
This expression displays the tools.bmp file:
Bitmap("TOOLS.BMP")This expression displays the tools.jpg file through an URL address:
Bitmap("http://172.16.5.175/tools.jpg")If the image file has no file extension, the method will check whether the file is a valid image file (a BMP, GIF, JPEG, RLE, or WMF file). For example, this expression displays the person file if it is a valid image file.
Bitmap("E:\images\person")This expression tests the value in the column named password and then uses the value to determine which image to display:
Bitmap(If(password = "y", "yes.bmp", "no.bmp"))
