Comments
.NET developers, see PeFunction.Image.PngToFile
Ocx|Vcl developers, see the PEactions property. OCX developers also see PEcopypngtofile method.
Using the OCX interface, you can call this function as follows
|
bResult = Pego1.PEcopypngtofile(nXPixels, nYPixels, strFilename)
or
Pego1.PEnarg1 = 'width in pixels
Pego1.PEnarg2 = 'height in pixels
Pego1.PEstrarg1 = 'filename
Pego1.PEactions = COPY_PNG_TO_FILE ' Calls PEcopypngtofile
|
In Delphi, use...
|
PEGraph1.PEnarg1 := {width in pixels};
PEGraph1.PEnarg2 := {height in pixels};
PEGraph1.PEstrarg1 := {filename};
PEGraph1.PEactions := gPngToFile; {Calls PEcopypngtofile}
