问题 Background: I'm developing Win 10 Universal App, have list of BitmapImage: List<BitmapImage> ImagesList = new List<BitmapImage>(); Each list item is created by converting byte[] to BitmapImage by this code: public async Task<BitmapImage> GetBitmapImage(byte[] array) { using (InMemoryRandomAccessStream stream = new InMemoryRandomAccessStream()) { using (DataWriter writer = new DataWriter(stream.GetOutputStreamAt(0))) { writer.WriteBytes(array); await writer.StoreAsync(); } BitmapImage image =

问题 My overall goal is to crop several regions from an input mirax (.mrxs) slide image to JPEG output files. Here is what one of these images looks like: Note that the darker grey area is part of the image, and the regions I ultimately wish to extract in JPEG format are the 3 black square regions. Now, for the specifics: I'm able to extract the color channels from the mirax image into 3 separate TIFF files using vips on the command line: vips extract_band INPUT.mrxs OUTPUT.tiff[tile,compression

问题 I'm trying to save a 32-bit floating point image (stored as a Numpy array) as a TIFF file using tifffile.py. import numpy as np import tifffile image = np.random.rand(500, 500, 3).astype(np.float32) tifffile.imsave('image.tiff', image) However, when viewing the output of the above code in Eye of Gnome, the image is entirely blank. 回答1: I think the problem is that not all tools support multi-channel TIFFs with 32-bits per channel. For example, as far as I can tell Python's PIL library does not

问题 Here's my problem : I need to create a TIFF and a PNG with a Palette containing specific colors and alpha. I am actually able to deal with the PNG but not with the TIFF. I've search on Internet and found out that TIFF should handle transparency, but that not all software can. I've tried many way to load the TIFF, but they all lead to a Palette with reseted Alpha values. So I think that the problem comes from how I save the TIFF, but I can't find any other way. Just in case : The palette is

问题 I have a tiff image of size 21 X 513 X 513 where (513, 513) is the height and width of the image containing 21 channels. How can I resize this image to 21 X 500 X 375? I am trying to use PILLOW to do so. But can't figure out if I am doing something wrong. >>> from PIL import Image >>> from tifffile import imread >>> img = Image.open('new.tif') >>> img <PIL.TiffImagePlugin.TiffImageFile image mode=F size=513x513 at 0x7FB0C8E5B940> >>> resized_img = img.resize((500, 375), Image.ANTIALIAS) >>>

问题 I'm looking for the best solution -- and perhaps the cheapest also -- to take PCL5e and PCL6 compliant code and render it into a TIFF image. Reliably. Does anyone have any experience with the PCLTool SDK from PageTech (http://www.pagetech.com/pcl.php)? This looks to be the best I can find, but I'm not sure how flexible it really is. The other options is trying to write my own interface, which would be a BEAST of a project and not one I really want to try to tackle. Any open-source solutions
