I've been looking at someone else's code from a 2007 posting. I'm using Gambas 3.0 with SQLite 3.6.22. I've done a similar piece of coding to that person to get the image from a file.
I get a popup window containing 'Null object' at runtime (which unfortunately does not point at problem line of code, though I think that it must be 'image = Image.Load(Dialog.Path)') with following code, when I click ButtonImportImage:
Public Sub ButtonImportImage_Click()
Dim image As Image
Inc Application.Busy
Dialog.Filter = ImageFileFilter(True)
Dialog.Title = "Import Image"
' load image
If Dialog.OpenFile() Then Return
Print "import image path=", Dialog.Path
image = Image.Load(Dialog.Path)
' save image & thumb to temp files
SaveImageAndThumb(image)
ButtonExportImage.Enabled = True
Finally
Dec Application.Busy
Catch
Message.Warning(ERROR.Text)
End
On execution, TempImagePath is valid and points to a .jpg file which loads with Graphics apps such as gThumbThumbViewer. I'm baffled as to the cause. Any ideas?
Grasping at straws: I'm using Gambas3 with SQLite 3.6.22. I just noticed that Gambas3 has a new component gb.image.io - image loading & saving. If I try and select it (in Project Properties) it seems to be incompatible with gb.gui, gb.gtk & gb.qt4. Perhaps it's needed for the Image.Load line - I need to load an Image for the SaveImageAndThumb procedure (which is working when called by another Sub).
