tiff

I am working on a website for my client in which tiff images need to converted to png or jpg before they are assembled into a PDF. I have read many articles, here and other sites, on this issue. They all recommend using Imagick to accomplish this. The problem is, my client's server does not have that extension installed, and the hosting company is unwilling to install the extension. Nor is PDFLib installed on the server (which supports importing tiffs into a PDF). Thanks. This is tricky because of the tiff format. You can do this for most input formats with native PHP functions to create an

I have noticed the Tensorflow Python package provides standard procedures for decoding jpeg , png and gif images after reading files. For instance for png : import tensorflow as tf filename_queue = tf.train.string_input_producer(['/Image.png']) # list of files to read reader = tf.WholeFileReader() key, value = reader.read(filename_queue) decoded_image = tf.image.decode_png(value) # use png or jpg decoder based on your files. However, the tiff format decoder seems to be missing. So what solutions exist for tiff files? Surely, I could convert my input images to png , but this doesn't seem to be

I need to convert bitonal (black and white) TIFF files into another format for display by a web browser, currently we're using JPGs, but the format isn't crucial. From reading around .NET doesn't seem to easily support writing bitonal images, so we're ending up with ~1MB files instead of ~100K ones. I'm considering using ImageMagick to do this, but ideally i'd like a solution which doesn't require this if possible. Current code snippet (which also does some resizing on the image): using (Image img = Image.FromFile(imageName)) { using (Bitmap resized = new Bitmap(resizedWidth, resizedHeight) {

I am working on reading text from an image through OCR. It only supports TIFF format images. So, I need to convert other formats to TIFF format. Can it be done? Please help by providing some references. If you create an Image object in .NET, you can save it as a TIFF. It is one of the many ImageFormat choices at your disposal. Example: var png = Image.FromFile("some.png"); png.Save("a.tiff", ImageFormat.Tiff); You'll need to include the System.Drawing assembly in your project. That assembly will give you a lot of image manipulation capabilities. Hope that helps. Intro Note: This answer cover

Following up my previous question: if and how would it be possible to take RGB based TIFF files and convert them over to CMYK with standard .NET (3.5) functionality? Is that possible at all? Jörg B. Actually there is a way using the System.Windows.Media.Imaging namespace which only seems to work properly with TIFFs at the moment (which is fine for me): Stream imageStream = new FileStream(@"C:\temp\mike4.jpg", FileMode.Open, FileAccess.Read, FileShare.Read); BitmapSource myBitmapSource = BitmapFrame.Create(imageStream); FormatConvertedBitmap newFormatedBitmapSource = new FormatConvertedBitmap()

I would like to use the original colortable of a >>georeferenced raster image<< (tif-file) as coloured scale in a map plotted by ggplot/ggplot2 . Due to not finding an easier solution, I accessed the colortable -slot from the legend -attribute of the loaded raster image (object) raster1 like so: raster1 <- raster(paste(workingDir, "/HUEK200_Durchlaessigkeit001_proj001.tif", sep="", collapse="")) raster1.pts <- rasterToPoints(raster1) raster1.df <- data.frame(raster1.pts) colTab <- attr(raster1, "legend")@colortable Ok, so far so good. Now I simply need to apply colortable as a colored scale to

I am looking at java APIs to convert JPEG file streams to TIFF files. I looked at the JAI but did not find something similar to what i am looking at. Can someone point me to a good API which does this ? objects There's an example here http://log.robmeek.com/2005/08/write-tiff-in-java.html and another here Tiff compression using Java ImageIO ImageMagick has a Java api available The javax.imageio package has built-in writers for most of the popular image types, including jpg and tiff. Here's Sun's page on imageio. http://java.sun.com/javase/6/docs/technotes/guides/imageio/index.html JIMI is
