Saving multiple images

[python_user]

Hi guys,

i have a problem here

i have a situation where i need to save all the images opened using PIL
I have no idea how to do without displaying images on screen one by one and saving them
Can anyone please help how to save them without switching on the screen

Thanks...

You don't need to display them, if you maintain a list of the image objects open, you can easilly save them all in a nice loop.

Show a example of what you mean, I'll help you.

Thank u for reply
here is the code for one image

def saveImage(self):
self.refreshImage()

name = asksaveasfilename(filetypes = [("Tif file",".tiff"),("Bmp file", ".bmp"),("Jpeg", '.jpeg'),("Gif",'*.gif')])

if name == "":
return

ext = name[name.rfind('.')+1:]
ext = ext.upper()

try:
self.curIm.save(name, ext)
except:
from tkMessageBox import showerror
showerror("Save error", "Save failed! Did you include a valid extension? (tiff, bmp, jpeg, gif, etc.)\ne.g. 'myimage1.tiff' and not just 'myimage1'.")

First wrap your code with Code-tags. You can do it easilly by selecting your code and clicking the code button.

And that code is useless mate. I mean you to show the code you use to open them.

And imports are done at the beginning of the script and never inside a function.

Sorrry here is the code for open image

def addImage(self, imageName):
    try:
        newImageData = {}
        im = Image.open(imageName)
        data = im.getdata()
        width, height = im.size
    except IOError:
        from tkMessageBox import showerror
        showerror( "File Error", "The selected file could either opened or converted." )
        return

    newImageData['im'] = im
    newImageData['data'] = data
    newImageData['width'] = width
    newImageData['height'] = height
    newImageData['id'] = -1
    newImageData['contours'] = []
    newImageData['dots'] = []
    newImageData['landmarks'] = []
    newImageData['linewidth'] = 1
    newImageData['linelength'] = 20
    newImageData['stack'] = self.getCurrentStack()
    self.imageInfo.append(newImageData)[/CODE]

here is the code for saving current selected image

def saveImage(self):
        self.refreshImage()

        name = asksaveasfilename(filetypes = [("Tif file",".tiff"),("Bmp file", ".bmp"),("Jpeg", '.jpeg'),("Gif",'*.gif')])

        if name == "":
            return

        ext = name[name.rfind('.')+1:]
        ext = ext.upper()
        
        try:
            self.curIm.save(name, ext)
        except:
            from tkMessageBox import showerror
            showerror("Save error", "Save failed!  Did you include a valid extension?  (tiff, bmp, jpeg, gif, etc.)\ne.g. 'myimage1.tiff' and not just 'myimage1'.")

Your import concept mate is totally wrong. You should read a good python tutorial.

Back to the code, something like

self.image_list = []

def addImage(self, imageName):
        try:
            newImageData = {}
            im = Image.open(imageName)
            data = im.getdata()
            width, height = im.size
            self.image_list.append(imageName)
        except IOError:
            showerror( "File Error", "The selected file could either opened or converted." )
            return

        newImageData['im'] = im
        newImageData['data'] = data
        newImageData['width'] = width
        newImageData['height'] = height
        newImageData['id'] = -1
        newImageData['contours'] = []
        newImageData['dots'] = []
        newImageData['landmarks'] = []
        newImageData['linewidth'] = 1
        newImageData['linelength'] = 20
        newImageData['stack'] = self.getCurrentStack()
        self.imageInfo.append(newImageData)

You can then use the image_list something like...

for image in self.image_list:
    ...

hey thanks for ur reply , i got it
we just have to say im.save
