If i'm getting a picture from the clipboard i have a stdPicture object: Code: Dim objStdPicture As StdPicture
Set objStdPicture = Clipboard.GetData(vbCFBitmap)
I want to load the picture in GraphicsMill. I have the following code Code: Dim objBitmap As GraphicsMill.Bitmap
Set objBitmap = CreateObject("GraphicsMill.Bitmap")
objBitmap.Data.Picture = objStdPicture
'select the format because no format is selected
objBitmap.Formats.SelectCurrent ("BMP")
If i look at the image ( using objBitmap.SaveToFile "c:\test.bmp" ) the image has the correct size but is white. How to capture a image in VB and how to set the objBitmap.Data.Picture? Or is this a problem in the trial version (besides white it also contains the added text from the trial)? Edited by user Wednesday, December 19, 2007 3:53:02 PM(UTC)

Most likely the problem is that you get 32-bit image that is considered by Graphics Mill as transparent. The workaround for it is to strip the bitmap of the alpha channel. The simplest way to do it is to convert it to 24-bit. Code:Dim objStdPicture As StdPicture
Set objStdPicture = Clipboard.GetData(vbCFBitmap)
Dim objBitmap As GraphicsMill.Bitmap
Set objBitmap = CreateObject("GraphicsMill.Bitmap")
objBitmap.Data.Picture = objStdPicture
objBitmap.Data.ConvertTo24bppRgb False
'select the format because no format is selected
objBitmap.Formats.SelectCurrent ("BMP")
It should help. Edited by user Wednesday, December 19, 2007 3:53:31 PM(UTC)

Thanks.
The workaround works.
Bug in Griphics Mill?
The origional image put on the clipboard did not have a alpha channel.

The 32bpp (with alpha) to 24bpp did work for the bitmap on the clipboard.
But it does not work al the time.
If i have a picture in Excel and copy it to the clipboard it is set on the clipboard as meta graphics.
Setting the picture from the clipboard direct to Griphics Mill fails. I can understand this because it is no bitmap image but a meta graphics (containing a bitmap).
If i convert it to a bitmap by painting it on a picturebox and then getting the image from it, i have a stdPicture object with a bitmap.
Setting this object on Graphics Mill works but i get a image with the correct size and totally black (not white as with the case before).
The format is again a 32bpp with alpha. But this time the conversion to 24bpp does not solve the problem. The picture stays black.
If i save the stbPicture to disk with the standard VB savepicture and read it in Graphics Mill with the loadfromfile then it does work. The SavePicture function saves a picture with 24bpp and not 32.
This works but is not preferred way because it is using a file.
Is there a solution for this?

Hello Rob, Could you submit case with the image which you save to file and then load into Graphics Mill? Edited by user Thursday, May 22, 2008 10:36:28 PM(UTC)
