I'm going to make a swf-file from a jpg file.
From an earlier discussion on the forum I found some code from you made for ASP.
I have used exactly the same code in VB, but do not obtain the expected result:

Code:
Dim bm As New GraphicsMill.Bitmap
bm.LoadFromFile "Z:\nina\bannere\alto.jpg"
bm.ApplyInPlace = True
bm.Data.ApplyInPlace = True
bm.Data.Channels.Transparentize &HFFFFFFFF, 30
bm.FormatAutoSelect = False
bm.Formats.SelectCurrent "swf"
bm.Formats.SwfBackgroundColor = &HFF00FF00
bm.Formats.SwfCompressionType = 0
bm.SaveToFile "Z:\nina\bannere\alto.swf"


I have checked that there really is a white (#FFFFFF) background on this picture, but I dont get any kind of transparency in the swf-file.

Any suggestions?

Regards

Erik

Hello Erik,

I think the problem is in the following line of code:

Code:
bm.Formats.SwfCompressionType = 0


As we have the following numeric values of compression type enumeration:

SwfCompressionTypeJpeg = 0 - JPEG compression,
SwfCompressionTypeLossless = 1 - lossless compression.

In fact only Graphics Mill 3.x for .NET supports alpha channel with JPEG compression in SWF, at that time as Graphis Mill 2.1 for ActiveX supports it with lossless compression only.

So way you should use:

Code:
bm.Formats.SwfCompressionType = 1

I have just found the same solution and now its working.
The penalty is that the swf-file (with my testfile) goes from 2 Kb to 10 Kb.
Do you think that there will be an upgrade to the ActiveX component?

That's why we have implemented JPEG with alpha channel support in .NET version .

We schedule to release update during the Fall, but if you need it urgently please submit case.
