Example

The following example converts a bitmap created in memory into JPEG format, then writes it to file.

dim saveb as B
dim savej as B
dim fptr as P
ui_bitmap_create("test", width, height)
ui_bitmap_draw("test",<<%code%
...
%code%)
saveb = ui_bitmap_save("test")
savej = bitmap_to_jpeg(saveb)
fptr = file.create("c:\was\chart.jpg", FILE_RW_EXCLUSIVE)
fptr.writeb(savej)
fptr.close()
