Using GDAL in Python, how do you get the latitude and longitude of a GeoTIFF file? GeoTIFF's do not appear to store any coordinate information. Instead, they store the XY Origin coordinates. However, the XY coordinates do not provide the latitude and longitude of the top left corner and bottom left corner. It appears I will need to do some math to solve this problem, but I don't have a clue on where to start. What procedure is required to have this performed? I know that the GetGeoTransform() method is important for this, however, I don't know what to do with it from there. fmark To get the

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 the total number of rows that I have by the number of rows per frame. It then uses the data as pixel

So I have been able to take a multi-page TIFF file and convert it to a single jpeg image but it flattens the TIFF. By flatten it, I mean it only returns the first page. The goal is to retrieve the TIFF (via memory stream), open each page of the TIFF and append it to a new jpeg (or any web image). Thus creating one long image to view on the web without the aid of a plugin. I do have the MODI.dll installed but I am not sure how to use it in this instance but it is an option. Source Code (using a FileHandler): #region multi-page tiff to single page jpeg var byteFiles = dfSelectedDocument.File

I'm looking for a library that can open and copy sections of a large TIFF file. I've looked at LibTiff.Net which opens the file very quickly but it doesn't have any functions for cropping or copying sections of the image. My image is 100,000 x 100,000 pixels upwards and creating a System.Drawing.Bitmap of that size crashes the application so converting to a Bitmap first is not an option. Can anyone recommend a .NET library? If your file is less than 4GB on disk than I recommend you to take another look at LibTiff.Net. Even with such large images you have some options. First of all, check

I'm interested in taking a tif image and adding a layer to it that contains text with Java, preferably with the Twelve Monkeys image library if possible. I can tweak the code from here to either add text to a tif or create a new tif of the same size with only text, but not save them as a multi-page tif. For example: import javax.imageio.*; import javax.imageio.stream.ImageOutputStream; import java.awt.*; import java.awt.image.*; import java.io.*; public class ImageUtil { public static void main(String[] args) throws Exception { BufferedImage src = ImageIO.read(new File("/path/to/main.tif"));

When I run the following code below in a command prompt (as administrator): "C:\Program Files\Windows Photo Viewer\PhotoViewer.dll" "C:\00012.tif" it produces error as shown below : "This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an associated in the Default Programs control panel." Both .tif and .tiff are associated in the Default programs control panel. I am trying to call this from a .net windows app. Any help is appreciated. RobinJ rundll32 "C:\Program Files\Windows Photo Viewer\PhotoViewer
