    Resolved [RESOLVED] How can I change by EMF byte array to jpeg file?

    should anyone show me a demo...
    i have been confused for long time.

    in post 14, dilettante kindly provided a demo of Load emf byte to a PictureBox and then save to jpeg file from the PictureBox

    that is a good demo, thanks dilettante, really.

    But i m a little puzzled, is there any more method of this converting

    like create a memory device context and then play emf bytes on it

    and then save as other types of picture.

    like Lavolpe said at this link: http://www.vbforums.com/showthread.php?640973

    1. Create blank EMF using desktop DC: GdipRecordMetafileStream
    2. Get EMF graphics: GdipGetImageGraphicsContext
    3. [added] Get previously created Region object & apply to graphics: GdipSetClipRegion
    4. Draw 24bpp source to EMF: GdipDrawImageRectRect
    5. Convert EMF to windows EMF: GdipGetHemfFromMetafile
    6. Convert EMF bits to WMF: GdipEmfToWmfBits
    7. Write bits to file & clean up
    maybe i will do some work at the base of dilettante's demo...

    question resolved.
