EmfToFile
public int PeFunction.Image.EmfToFile( int width, int height, string fileName, ProEssentials.Enums.EmfType emfType, ProEssentials.Enums.EmfDC emfDC, bool emfBitmapGradients )
|
Parameter
|
Description
|
|
width
|
Width in 1/100th millimeters. The dimensions must not equal zero. To insure image quality, the aspect ratio (width/height) must be between 0.333 and 10.0 |
|
height
|
Height in 1/100th millimeters. The dimensions must not equal zero. To insure image quality, the aspect ratio (width/height) must be between 0.333 and 10.0
|
|
fileName
|
Must identify a valid filename.
|
|
emfType
|
EmfType.Gdi (0)
|
|
Legacy GDI enhanced metafile, converted via GDIPlus to simulate GDIPlus within GDI . Highly supported.
|
|
Dual format: renders as GdiPlus if available, else renders as Gdi if GdiPlus is not available. File size is usually quite large. MS Office and Adobe supported, though large sized fonts tend to be quirky. Test for Adobe support if you want to print to a PDF. Hopefully Microsoft will improve their poor support for this image format.
|
|
Renders as GdiPlus only. File size is very small. GdiPlus must be present and this format has limited support. MS Office/Adobe may not fully support. Test thoroughly if using this setting. Hopefully more support will arrive as file-size and image-quality is best within this format.
|
|
emfDC
|
EmfDc.DisplayDpiAdjusted (0)
|
|
Uses the current video display Device Context. Metafile header is not modified, and DPI of the metafile will match the DPI of the video display. Best if export will only be viewed on a monitor and never printed.
|
|
Uses the current default printer driver. This setting may be the best solution if ExportImageDpi will be set to 300 DPI.
|
|
emfBitmapGradients
|
If True, file sizes may be large and radial gradients may show artifacts when nEmfType is 0. Linear gradients are well supported. If False and BitmapGradientMode = True, then the background region will be transparent. In this case, it's best to use black or dark colored chart text.
|
This function places the current image, in the form of an enhanced metafile, into a file named by fileName. It is recommended that ExportImageDPI is set to 300 DPI.
Returns
Non-zero if successful, else zero.

PeFunction.Image.EmfToFile members of Pego.PeFunction.Image, Pesgo.PeFunction.Image, Pe3do.PeFunction.Image, Pepso.PeFunction.Image, Pepco.PeFunction.Image
The metafile created is an Enhanced Metafile or Enhanced Plus Metafile (supporting GdiPlus). Standard metafiles are exported with Metafiletofile.
