tiff

问题 We have a image, but it's showing flipped on Google Chrome, Safari, iOS and iPhone. But image showing correctly on IE and Android. How it could be? 回答1: The image is shown rotated because it contains an Exif Orientation field which is set to "Rotate 90 CW" (value 6). This could happen if the image was rotated in software that don't also update the Exif data. Chrome, Safari et al is honoring this field, while the software that shows the image "correctly" doesn't. According to the Exif fields,

问题 I want to create a Tiff file from a Datagridview. I was able to get the Datagridview to a Tiff file, however I just want the Rows and Columns and nothing else. Is this possible without using 3rd party Tool? Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load DataGridView1.Rows.Add(New String() {"Value1", "Value2", "Value3"}) Dim height As Integer = DataGridView1.Height DataGridView1.Height = DataGridView1.RowCount * DataGridView1.RowTemplate.Height Dim bitmap As

问题 How would I go about creating a new image, using python PIL, which has multiple frames in it. new_Image = Image.new("I;16", (num_pixels,num_rows)) for frame in range((len(final_rows)/num_rows)): pixels = new_Image.load() for row in range(num_rows): row_pixel = final_rows[row].getPixels() for pixel in range(num_pixels): pixels[pixel,row] = row_pixel[pixel] print frame new_Image.seek(frame) I tried using the above code but it gives me a EOFError. The code gets the number of frames by dividing

问题 EPS files can include embedded TIFF (and rarely WMF) previews for easy rendering in environments which do not have PostScript available. (See Wikipedia for more info.) Given such an EPS, how can I extract the TIFF into a separate file using MATLAB? 回答1: % Define the source EPS file and the desired target TIFF to create. source = 'ode_nonneg1.eps'; target = 'ode_nonneg1.tif'; % Read in the EPS file. f = fopen(source,'rb'); d = fread(f,'uint8'); fclose(f); % Check the header to verify it is a

问题 I'm reading in a Tiff using the below function, which works fine, but when I try to use my write function to write that same Tiff back to a different file, it's all 255's. Does anyone know how to fix this? Thanks, Alex. function Y = tiff_read(name) % tiff reader that works info = imfinfo(name); T = numel(info); d1 = info(1).Height; d2 = info(1).Width; Y = zeros(d1,d2,T); for t = 1:T temp = imread(name, t, 'Info',info); Y(:,:,t) = temp(1:end,1:end); end % Tiff writer that doesn't work function

问题 I'm a beginner in Java and a geomatics student. I'am using IntelliJ. I would like to create a TIFF from a BufferedImage. This is my code : byte[] buffer = new byte[width * height]; ColorSpace cs = ColorSpace.getInstance( ColorSpace.CS_GRAY ); int[] nBits = { 8 }; ColorModel cm = new ComponentColorModel( cs, nBits, false, true,Transparency.OPAQUE, DataBuffer.TYPE_BYTE ); SampleModel sm = cm.createCompatibleSampleModel( width, height ); DataBufferByte db = new DataBufferByte( buffer, width *

问题 I want to add temperature data of image at selected point. Is there any pre defined property of it or does we can create custom/ private keys in Tiff file to store temperature data of image. Answer: Use TIFF Library documentation to create your own custom keys in TIFF file. in documentaiton he mention how to create and use of custom keys. http://www.libtiff.org/libtiff.html 回答1: You can't add custom EXIF keys, but you may be able to cheat... You could look up the available keys and see if any

问题 I'm processing huge TIFF images (grayscale, 8 or 16 bit, up to 4 GB) to be used as high resolution input data for a machine. Each image needs to be rotated by 90 degrees (clockwise). The input TIFF can be LZW or uncompressed, the output may be uncompressed. So far I implemented my own TIFF reader class in Objective C (including LZW decompression) which is able to handle huge files and does some caching in memory as well. At the moment the TIFF reader class is used for visualization and

问题 This is the JavaScript code I use to load files from an input element. Image format includes jpeg, png, tiff. $(document).ready(function() { FileDetails = function() { var input = document.getElementById('fileUpload'); var output = document.getElementById('tblUpload'); //' + (URL || webkitURL).createObjectURL(input.files[i]) +' output.innerHTML = '<tr>'; output.innerHTML += '<th class="thStyle" style="width: 400px;"><b>File Name</b></th><th class="thStyle" style="width: 150px;"><b>Preview
