PIL: Image.draft -- what are the modes that I can use?
I have PIL 1.1.5 on python 2.4.1 and I am attempting to get a smaller (file size) of an image. for example: im = ImageGrab.grab() im.save(tmp.gif) about 1.7mb im.save(tmp.jpeg) about 290kb anyways I want to save the image as a GIF, but not have it be so largeso I thought that the Image.draft method would be what I wanted im.draft(mode, size) Configures the image file loader so it returns a version of the image that as closely as possible matches the given mode and size. For example, you can use this method to convert a colour JPEG to greyscale while loading it, or to extract a 128x192 version from a PCD file. .what 'modes' can I use? or is there another way to shrink the size of the image (other than resizing it)? thanks -- http://mail.python.org/mailman/listinfo/python-list

oh and vnc2swf would not be an option, i cant be setting up a vnc server, etc. just need to use python (and necessary packages). animated gif would probably be best i am assuming. -- http://mail.python.org/mailman/listinfo/python-list

Re: Image.draft -- what are the modes that I can use?
fredrik, in other posts you have mentioned the use of gifmaker. i have tried that with the following: I am using gifmaker.py from PIL v1.1.5 on python 2.4.1. CODE import ImageGrab, gifmaker seq = [] while keepOnGoing: im = ImageGrab.grab() seq.append(im) fp = open(out.gif, wb) gifmaker.makedelta(fp, seq) fp.close() --- however I am getting this error: Exception in thread Thread-3: Traceback (most recent call last): File c:\Python24\lib\threading.py, line 442, in __bootstrap self.run() File c:\foo.py, line 10, in run gifmaker.makedelta(fp, seq) File c:\gifmaker.py, line 79, in makedelta for s in getheader(im) + getdata(im): File c:\Python24\Lib\site-packages\PIL\GifImagePlugin.py, line 383, in getdata ImageFile._save(im, fp, [(gif, (0,0)+im.size, 0, RAWMODE[im.mode])]) KeyError: 'RGB' Any ideas? Basically I want to make an animated GIF out of a bunch of images taken using the ImageGrab module. -- http://mail.python.org/mailman/listinfo/python-list
