IMAGE property (deprecated in OI 10)

Bitmap, checkbmp, pushbmp

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.

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

/*  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)

BITMAP property

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

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.
