Graphics - fimg function, OnImageFormat event.
Posted by - NA - on 11 March 2005 10:58 PM
A graphic image may be inserted from a blob, graphic field or from an external graphic file, using function fimg. For example: \fimg(a:field2)\, \fimg(a:field2,1)\.


Function format for blobs and graphic fields is: \fimg(FieldName,[FormatIndex])\, where FieldName is the name of the data field. FormatIndex is the number which will be passed into OnImageFormat event. This parameter is 0 by default and is not required. You may use this number in event OnImageFormat when formatting different images in the report.


The function format for variables is the same: \fimg(VarName,[FormatIndex])\. The variable VarName must contain a string with the filename to be inserted in the report. For example: if the variable MyPicture='c:\pictures\chart1.bmp', in the report template may be string \fimg(MyPicture)\. String constant is also allowed as argument for fimg format.


You may insert graphics through the user defined function.
