tiff

问题 So I have been able to take a multi-page TIFF file and convert it to a single jpeg image but it flattens the TIFF. By flatten it, I mean it only returns the first page. The goal is to retrieve the TIFF (via memory stream), open each page of the TIFF and append it to a new jpeg (or any web image). Thus creating one long image to view on the web without the aid of a plugin. I do have the MODI.dll installed but I am not sure how to use it in this instance but it is an option. Source Code (using

问题 Each tiff file has 4 images in it. I do not wish to extract and save them if possible, I would just like to use a for loop to look at each of them. (Like look at the pixel [0,0] )and depending on what color it is in all 4 I will do something accordingly. Is this possible using PIL? If not what should I use. 回答1: You can use the "seek" method of a PIL image to have access to the different pages of a tif (or frames of an animated gif). from PIL import Image img = Image.open('multipage.tif') for

问题 I need a python routine that can open and import TIFF images into numpy arrays, so I can analyze and modify the contained data and afterwards save them as TIFFs again. (They are basically light intensity maps in greyscale, representing the respective values per pixel) I tried to find something, but there is no documentation on PIL methods concerning TIFF. I tried to figure it out, but only got bad mode/ file type not supported errors. What do I need to use here? 回答1: First, I downloaded a

问题 I have an ASP.NET application (vb.net codebehind) that has serious performance problems because of its storage of TIFF files in one server share. There are over a million .TIF files there now! The application tracks the scanned images of property with a corresponding row in an Oracle database table. We have this idea that it might be better to store the images themselves in a new Oracle table. How can this be done? The alternative solution we are thinking of is to split up the server share

问题 I have an image sequence and I am trying to run a script on a specific frame. I need to switch to this frame and convert it to an array. However, I am unable to as the frame is an instance <TiffImagePlugin.TiffImageFile image mode=I;16 size=512x512 at 0x104A0C998> . How can I convert this instance to an array? I have already used numpy.array and it does not work. Thank you! prot=Image.open("F23BN.tif") for frame in ImageSequence.Iterator(dna): if frame==16: frame.convert('L') print frame.mode

问题 I would like to include a TIFF image into my PostScript similarily to an EPS and a JPEG. But it fails on creation stating the file ImageType isn't JPEG. Is this possible? 回答1: You can't use a TIFF directly in PostScript, as PostScript doesn't support the TIFF file format. You can use a PostScript program to read a TIFF file and process it as an image, for example : Conversion of TIFF to PDF with Ghostscript 来源： https://stackoverflow.com/questions/30707216/how-to-insert-a-tiff-into-postscript

问题 For example, how to make the following HTML page actually display the image, in an Android WebView? <html> <body> <img src="http://www.alternatiff.com/sample.tif"> </body> </html> Any (hacking) suggestion is appreciated. I am only an app developer and cannot control the whole system, so modifying the OS source code is not applicable. 回答1: I haven't tried this, but this is what I would do: Make a subclass of WebViewClient Override shouldInterceptRequest() to check the URL and see if a TIFF was

问题 I have imported a greyscale 16-bit image. I have it bot as a BitmapSource and an Image (of Controls namespace). How can i access the individual pixels? Is the CopyPixels i have read about the only or best way? If so, i don't get how to set the stride, and which pixel contains the pixel intensity value.
