Hi,
Today i propose to your an example to manage scanner in gambas 3.
Result will be displayed in a picturebox


A)probe of your scanner
to owner of scanners, write this command line in linux terminal:

scanimage -L

you should see line as this:

device 'brother4:bus3;dev3'

B) create new gambas project
create new application or open source code bellow.


C) Here code of this example:


Private myscan As Scanner

Public Sub Button1_Click()
Dim myimg As Image
myimg = myscan.Scan()
PictureBox1.Image = myimg
End

Public Sub Form_Open()
Me.Center()
myscan = New Scanner("brother4:bus3;dev3")
End


Public Sub binfo_Click()
If myscan.IsAvailable() Then 'Test if scanner is online and available return one boolean
Label1.Text = "scanner connected"
Else
Label1.Text = "Scanner not connected"
Endif
lname.Text = myscan.Name 'return our brother4:bus3;dev3 text
lmodel.Text = myscan.Model 'return string model of your scanner
lvendor.Text = myscan.Vendor 'return string vendor of your scanner
ltype.Text = myscan.Type 'return string connection type of your scanner
End

Public Sub CheckBox1_Click()
PictureBox1.Stretch = CheckBox1.Value
End


one remark :
To create new scanner "myscan" in Form_open, i need to give name of my scanner. that's why i need to launch terminal with scanimage -L command.

well, to start simple scan, write this command myscan.scan()
result will be in picturebox.

Thanks for your attention.
