tiff

问题 The file exists, path is correct, however I cannot load the .tif file. Please send help? Here's the code .. import os from PIL import Image name = 'PE-0D8-4m-10s-0001_00009_bbo.tif' THIS_FOLDER = os.path.dirname(os.path.abspath(__file__)) filename = os.path.join(THIS_FOLDER, name) image = Image.open(filename) And here's the traceback: Traceback (most recent call last): File "C:\Users\owner\MATLAB Drive\Python\imageload.py", line 23, in <module> image = Image.open(filename) File "C:\Users

问题 While saving jpg thumbnails from tiff (CMYK) file I'm encountering the following problem: Thumbnail created with color mode conversion from CMYK to RGB gets blue hue: Thumbnail created from the same tiff in photoshop (no ICC profile, not converted to sRGB, RGB only) get the colors the right way: Thumbnails created without color mode conversion (jpeg with CMYK) gets similar results to the photoshopped ones but are not usable for the web (still blue). Code snippet: img = Image.open(img_tiff)

问题 I'm using python (cv2) to import a .tif file with three layers, but I only seem to be able to import one layer. How can i separately import all three layers? import cv2 img = cv2.imread('LanB2_KD1P2_31603_gut_2.tif', cv2.IMREAD_COLOR) #extract blue channel blue_channel = img[:,:,0] #write blue channel to greyscale image cv2.imwrite('blue_channel.jpg',blue_channel) this extracts the blue channel from the first layer but idk how to get the other layers 回答1: You can simply use cv2.split for

问题 I need to display the 3rd page of scanned tiff files. i used the code TIFFReader reader = new TIFFReader(new File(pathOfFile)); RenderedImage image = reader.getPage(2); its sometimes work. and show error : Decoding of old style JPEG-in-TIFF data is not supported. I used aspriseTIFF.jar then how i solve this problem. please reply. thanks in advance 回答1: The problem you have run into is that "old style" JPEG compression in the TIFF format ( compression == 6 ), is not supported in the library

问题 I am using this code snippet to load various image files: BitmapImage bitmap = new BitmapImage (); bitmap.BeginInit (); bitmap.UriSource = new System.Uri (path); bitmap.CreateOptions = BitmapCreateOptions.PreservePixelFormat; bitmap.EndInit (); This works fine for TIFF files stored as RGB, RGB+Alpha and CMYK. However, if I try to load a TIFF file using CMYK colors and an alpha channel, I get an exception (the file format is not recognized as being valid by the decoder). I was previously using

问题 I'm trying to find a library that will allow me to create tiffs with an arbitrary amount of channels such as how Photoshop allows it to happen. Specifically, I need to write a 6 channel TIFF (CMYK w/ 2 channels to represent white), but all the libraries/scriptable tools im finding max out at RBGA. Any ideas on how to program this? Details on What I'd Like From @BitBank's question below. I'd prefer to not implement the adobe tiff spec myself. Operating environment Ubuntu/Windows Server FOSS
