====== IMAGE property (deprecated in OI 10) ======


 
==== Applies To ====
 
Bitmap, checkbmp, pushbmp
 
==== Description ====
 
[[set_property|Set_Property()]] sets the bitmap control to display the raw image, as actually read from an image file.  This contrasts to the [[bitmap|BITMAP property]], which directs the control to the location of the image file.
 
==== Usage ====
 
//retval// = **Set_Property**(//bitmapcontrolname//, "IMAGE", imagefile_contents)
 
==== Example ====
 
<code>
/*  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)

</code>

 
==== See Also ====
 
[[bitmap|BITMAP property]]
 
==== Remarks ====
 
The IMAGE property supports .BMP, .ICO, .WMF, and .PCX file formats.

==== Notes ====

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

When using [[set_property|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.
