How to create a TIFF file in PHP? I want create a TIFF file and fax it. I know how to fax it but I don`t know how to create a TIFF file. Jaimz Yes, ImageMagick . Don't count on trying to use the PHP extension for it though, you're going to be making shell commands to the convert command. It's as simple as: system('/path/to/imagemagick/convert orginal_image.jpg new_image.tiff'); Hope that helps. Aneeska ImageMagick is the solution. 来源： https://stackoverflow.com/questions/1951101/how-to-create-a-tiff-file

I'm using iText to extract embedded images and save them as separate files. The .jpg and .png files come out ok, but I cannot extract tiff images that have the CCITTFaxDecode encoding. Does anyone have a way of saving the tiff files? I found some sample C# code that uses iTextSharp at Extracting image from PDF with /CCITTFaxDecode filter It indicates a separate tiff library is needed to write out the results. According to that article, the "CCITTFaxDecode" compression is Compression.CCITTFAX4 for the tiff library. To use that article's method, I need: 1. get a tiff library. The Java Image I/O

What's the best way to split a multi-page TIFF with python? PIL doesn't seem to have support for multi-page images, and I haven't found an exact port for libtiff for python. Would PyLibTiff be the way to go? Can somebody provide a simple example of how I could parse multiple pages within a TIFF? I do use ImageMagick as external program to convert multi-page fax into viewable PNGs: /usr/bin/convert /var/voip/fax/out/2012/04/fax_out_L1_17.tiff[0] -scale 50x100% -depth 16 /tmp/fax_images/fax_out_L1_17-0-m.png does convert first page to PNG aaa.tiff[1] would be second page, and so on. Or to

I am having issues converting a png to tiff. The conversion goes fine, but the image is huge. I think the issue is that I am not doing the compression correctly? Anyone have any suggestions?? Here is the code sample public static void test() throws IOException { // String fileName = "4958813_1"; String fileName = "4848970_1"; String inFileType = ".PNG"; String outFileType = ".TIFF"; ImageIO.scanForPlugins(); File fInputFile = new File("I:/HPF/UU/" + fileName + inFileType); InputStream fis = new BufferedInputStream(new FileInputStream( fInputFile)); PNGImageReaderSpi spi = new PNGImageReaderSpi

I am able to convert a single page TIFF to a PNG in .Net, however, how would I do this for a multipage TIFF? You should select active frame (page) in a loop and convert each tiff page to a png. int pageCount = 1; try { pageCount = bmp.GetFrameCount(FrameDimension.Page); } catch (Exception) { // sometimes GDI+ throws internal exceptions. // just ignore them. } for (int page = 0; page < pageCount; page++) { bmp.SelectActiveFrame(FrameDimension.Page, page); // save or otherwise process tiff page } This code assumes that you can load Tiff image in System.Drawing.Bitmap object.

I know libtiff for C, but haven't found a port for .NET. Does such a port exist? Bobrovsky My company recently released a free and open-source(New BSD license) version of LibTiff written using only managed C# (license permits commercial use and distribution). http://bitmiracle.com/libtiff/ What about using the built in .NET class?

Please bear with me as I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too. Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive. The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their

A journal we are sending an article to is asking for the following: To ensure the best reproduction quality of your figures we would appreciate high resolution files. All figures should preferably be in TIFF or EPS format... and should have the following resolution: Graph: 800 - 1200 DPI Photo: 400 - 800 DPI Color (only CMYK): 300 - 400 DPI (DPI = dots per inch) Since I am sending a graph, I am trying to save it using tiff. Here is the code I am using: tiff(filename = "c:\\aaa.tiff", res = 800, pointsize = 2) plot(1:100) dev.off() But sadly, it produces a very "bulky" image - and if I where to

Does anyone have a method for importing a 16 bit per channel, 3 channel TIFF image in Python? I have yet to find a method which will preserve the 16 bit depth per channel when dealing with the TIFF format. I am hoping that some helpful soul will have a solution. Here is a list of what I have tried so far without success and the results: import numpy as np import PIL.Image as Image import libtiff import cv2 im = Image.open('a.tif') # IOError: cannot identify image file tif = libtiff.TIFF.open('a.tif') im = tif.read_image() # im only contains one of the three channels. im.dtype is uint16 as
