Has anyone else had problems with saving vector graphics as .emf files? Code that used to work pre-Xojo doesn’t work anymore and even the VectorGraphics example project only saves low resolution rasters (and bombs when one tries to load the file they created). I know that PICTs have been deprecated in Mac OS X, but my Windows users are complaining that .emf no longer works. For reasons I don’t quite understand, they prefer emf to pdf…
I am using Xojo 2013 v. 3.1.
emf vs pdf
Note that I never saw / create an emf file, but I know what a vector pict was
how do you edit a pdf in your software ?
If I had now, I use The GIMP, but I am not sure it will stay vector at GIMP save time.

A feedback report & example would be good
I Just opened the Vector graphics example in 2013r4.1, ran it, saved the EMF & can open it in a few MS Apps (Paint & WordPad)
Don’t have a lot of other tools to work with them
Moved the EMF to my mac & opened it there as well
Yes, VectorGraphics saves a file but the file contains a raster image, not vector graphics that can be edited in a program like CorelDraw, Canvas, etc. The code that VectorGraphics uses looks like this:
Dim group As New Group2D
group.Append®
group.Append(s)
mSavePicture = New Picture(Me.Width, Me.Height, 32)
mSavePicture.Graphics.DrawObject(group, 100, 100)
g.DrawPicture(mSavePicture, 0, 0)
where the group contains 2 RoundRectShapes. In the save button:
Dim file As FolderItem
file = GetSaveFolderItem("", “vector”)
If file <> Nil Then
mSavePicture.Save(file, Picture.SaveAsDefaultVector)
End If
This produces a file containing a low resolution (72 dpi) bitmap image of the vector graphics, not editable vectors as previously.
if one changes " mSavePicture.Graphics.DrawObject(group, 100, 100)" to “mSavePicture.Objects = group” (which used to work) the resulting file saved is empty.
I’m happy to submit a feedback report but wanted to make sure I have not missed some deprecated commands, a change in how Xojo operates, or have screwed up my own code somehow (very possible)
Ah right you are about the raster
Missed that in quick look I took at the example
I’m not aware of any recent changes
Which version was your software previously compiled in ?
I’d still submit a feedback report as well
Thanks for confirming.
This seemed to occur on the switch from RealBasic to Xojo, though I’m not 100% sure as all my own work is in MacOS X and I simple compile for Windows with only cursory testing (these are free scientific programs for academic users so the scientific routines are tested much more rigorously than the interface routines…)
