Description

Set_Property() sets the bitmap control to display the raw image, as actually read from an image file. This contrasts to the BITMAP property, which directs the control to the location of the image file.

Usage

retval = Set_Property (bitmapcontrolname, "IMAGE", imagefile_contents)

Example

/*  read the contents of the JPEG image file my_pic.jpg, into a variable.  
Then, set the bitmap control (BITMAP_1) to display the contents of the variable as an image.  */
declare function Set_Property
declare subroutine fsmsg
OSOpen 'my_pic.jpg' to pic_filehandle else
   fsmsg()
   return 1
end
OSBRead picdata from pic_filehandle at 0 length 999999
retval = set_Property(@window : '.BITMAP_1', 'IMAGE', picdata)

Remarks

The IMAGE property supports .BMP, .ICO, .WMF, and .PCX file formats.


Note: The IMAGE property does not support the .GIF file format.

When using Set_Property() to set multiple properties, set the IMAGE property last, because the image file most probably contains control characters that will cause Set_Property to function improperly.
