Hi again, Some more questions about tiff conversion.
First, thanks for your previous replies. I cannot use IrfanView any time soon, nor will my boss switch to Linux. So I'm trying to do the conversion from tiff to png using the wx package (gif would also be fine, but that won't work due to copyright issues -- I pulled about half of my hairs out before I found that out ;-). I have to access the second page of the tiff file, then write it to a png file. The code below (see also http://codepad.org/CV9xZXgi) works for one file only. Two questions: 1--- the program gives a 'tiff library warning', which is related to multipage tiff files (http://libtiff.maptools.org/man/TIFFReadDirectory.3tiff.html), but it generates the same warning with a single page tiff. The warning is given in a little menu (annoying!). How can I prevent or suppress this warning? This is the complete warning log: 17:49:54: tiff module: TIFFReadDirectory 17:49:54: TIFF library warning. 17:49:54: tiff module: TIFFReadDirectory 17:49:54: TIFF library warning. 17:49:54: tiff module: TIFFReadDirectory 17:49:54: TIFF library warning. 2--- the program is not closed properly (despite of the destroy() call). What should I do to correct this? As always, thanks in advance for your replies. Best wishes, Albert-Jan import wx, Image import os, glob class MyFrame(wx.Frame): def __init__(self, parent, id, title): self.tifLoc = tifLoc self.debug = True wx.Frame.__init__(self, parent, id, title, size = (600, 800)) SECONDPAGE = 1 self.image = wx.Image(name = self.tifLoc, type = wx.BITMAP_TYPE_TIF, index = SECONDPAGE) if self.debug: h, w = self.image.GetSize() print "Reading file '%s' of %s x %s pixels" % (self.tifLoc, h, w ) self.bitmap = wx.BitmapFromImage(self.image) wx.EVT_PAINT(self, self.OnPaint) self.Centre() def OnPaint(self, event): dc = wx.PaintDC(self) dc.DrawBitmap(self.bitmap, 0, 0) self.saveIt() def saveIt(self): pngLoc = os.path.splitext(self.tifLoc)[0] + ".png" self.bitmap.SaveFile(pngLoc, wx.BITMAP_TYPE_PNG) class MyApp(wx.App): def OnInit(self): frame = MyFrame(None, -1, 'My file') frame.Show(False) # do not show pic self.SetTopWindow(frame) if frame.debug: print "... Conversion done!" return True path = "d:/temp" for f in glob.glob(os.path.join(path, "*.tif")): tifLoc = f app = MyApp(0) app.MainLoop() app.Destroy() Cheers!!
