Issues: METAFJAVA-20446 (Fixed)

How to get original wmf values

we are evaluating the aspose.metafiles for java library.

it does successfully convert our wmf file(s) to png(s). but our application logic requires more information about the conversion. how can we get the meta information about the image before the conversion? for instance:

we have a wmf file -- when opened with windows picture viewer, for example, shows:
width pixels = 10,123
height pixels = 12,935
dpi = 1440

when converting that wmf using WmfMetafile, we get these properties from the WmfMetafile object:

width pixels = 675
height pixels = 862
dpi = 96

those values appear to be what the resulting image is after the conversion, which are fine, and the conversion looks great. but programmatically, we need access to the meta info before the conversion, so that we can compare them to the meta info after the conversion, so that we can see the scale factor.

how can we get this data from the Aspose library?

Re: How to get original wmf values

Hello Paul,

Sorry for replying you late.

We are about to release a new version of Aspose.Metafiles for Java in which WmfMetafile class will contain following new methods that can help you in accomplishing your requirements.

getDpi(..) Returns metafile's DPI.
getMuFrame(...) Returns metafile's position and size in internal metafile units.
getMupi(...) Returns number of metafile's units per inch.

As soon as the new version becomes available, we would be pleased to share that information. Please be patient and spare us little time.
