tiff

问题 Where can i find Tiff annotations (Wang/Kodak) format specs? Need to parse some of them and put to text file. Wasted many hours googling with no result. What SDKs for .NET can operate with that tags? Free sdk's are preferred. Libtiff has limit of 32K to any tiff tag but some of annotation tags such as bitmap can be longer. Thanks! 回答1: The spec is public, but the content holder (eistream) took down their website a few years ago. It is currently being preserved on the web archive here: http:/

问题 I've got two tiff stacks with time-lapse data corresponding to different channels acquired in a microscopy experiment. I'd like to merge them into a single stack with two channels. Both stacks are 16-bit greyscale. When I use: convert stack1.tiff stack2.tiff stack_merged.tiff I get a single but concatenated file with two stacks one after another. Links to file 1 and file 2. 回答1: I think you need something like this: #!/bin/bash # Get index of last frame in TIFF image last=$(convert stack1.tif

问题 I have TIFF file which contains multiple images , I will need to loop through that TIFF file to extract the images seperately , I have used base64 encode, then used substring to seperate the images and used base64 decode to write in a filesystem, However only some images are able to extract. Example : I have 7 Images in a tiff file but it extracted only 4 images. So I have write the encoded data to a file and read that and I can only able to see the II* encode character as 4 places instead of

问题 I am using MVC 4 to build a web application. I need to implement a functionality that will convert multiple Tiff images to a single PDF. I have looked at things like ItextSharp. Has anyone else done something like this before? what tools/libraries have you used? Thanks 回答1: I am big fan of ImageMagick. Though it can do so much more than file conversion, it does do that pretty well. Use the .NET library Magick.NET Here is some sample code to convert to PDF To test using the command line tool,

问题 I need to read thousands of TIF files (3500x3500 in size) in a loop. And imread is the biggest bottleneck. I only work on a small section of the image for which I have the row-col extent. Is there anyway to import a subsection of the image to improve the import process substantially? Any other suggestions? This is the import section of the code: for m = 1:length(pFileNames) if ~exist(precipFileNames{m}, 'file') continue; end pConus = imread(pFileNames{m}); end P.S. I tried to use PixelRegions

问题 I know android does not support TIFF format but I'm getting a Base64 image string from a web service and i need to display it. byte[] decodedString = Base64.decode(serverResponse, Base64.DEFAULT); Bitmap imgMap = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); I tried decoding it with BitmapFactory, but since it doesn't recognize it as a picture it returns null Is there any external jar or something i can add to display/convert the picture? Thanks in advance for your

问题 I have 2 same size, dimensions, and resolution images in TIFF (6400x6400 pixels, 800x800 ppi). The files are 18.7MB and 27.0MB, they were created with R's tiff() with compression="lzw" . When I try to create a tile using montage -compress lzw -tile 2x1 -geometry +0+0 Figure4L.tiff Figure4R.tiff Figure4.tiff I get a file 12800x6400 TIFF which has a size of 12.8 MB, GIMP reports a resolution of 72 x 72 ppi. GIMP also reports "Warning:The image you are loading has 16 bits per channel. GIMP can

问题 I am having a problem converting an image I;16 to JPEG with PIL. My original image can be found here (as pickle). The original image comes from a DICOM file. Here is the code to try: import pickle import matplotlib.pyplot as plt from PIL import Image ims = pickle.load(open("pixel_array.pickle", "rb")) img = Image.fromarray(ims) print(img.mode) rgb_im = img.convert("RGB") print(rgb_im.mode) fig, ax = plt.subplots(figsize=(20, 10)) ax.imshow(rgb_im, cmap=plt.cm.bone) fig.show() Unfortunately

问题 On client side I have image in TIFF images with multiple pages. Firt I convert this image file to byte array and then I sent this data to web service. For converting TIFF to byte array I use method System.IO.File.ReadAllBytes . On web service side I would like convert this byte array to If byte array contains invalid data it will be nice to have som control. Then I need do these things: parse all pages from multi TIFF image to objects type of System.Drawing.Image get specified images from

问题 I have a little console application in C# that takes a pair of pictures from a folder (containing a few hundred images) in .jpg-format, merges them to one picture and stores the result as .tif in another folder. This process is repeated for all pictures in the source folder. It works fine for a few loop iterations, but then I get an unhandled external exception with an GDI+ generic error (the inner exception is null) when trying to save the result. As I create new files for storing and as it
