Antonio OREFICE reported a new bug.
Summary
---
Gambas should trow an error or at least a warning when loading corrupted images
Type : Bug
Priority : Medium
Gambas version : Unknown
Product : Unknown
Description
---
See the following code:
Public Sub Form_Open()
Dim myimage As New Image
Dim mydata As String
Dim tmpfile As String = "/tmp/myimage.jpg"
myimage.Resize(100, 100)
myimage.Fill(Color.black)
myimage.Save(tmpfile)
mydata = File.Load(tmpfile)
mydata = Left(mydata, Len(mydata) - 100)
File.Save(tmpfile, mydata)
Try myimage = Image.Load(tmpfile)
If Error Then
Debug "Error while loading the image"
Endif
End
No Error is catched, because gambas loads the corrupted image.
Still, in the console log something throws the error/warning
"Corrupt JPEG data: premature end of data segment"
But, actually, i can't see a way to handle that at code level.
Is there a workaround or this is in the need of a fix?
Thanks.
