1. Introduction: If you use Xcode 5 or 6 to develop Mac applications, you may already know that it combines pairs of non-Retina images and Retina images to create TIFF packages.  That's what you find in an application package.  TIFF is a container format.  So it can contain multiple images.

tiffPack is a desktop application that lets you create TIFF packages.  An advantage of using tiffPack is that it'll take this application Retina images (72 dpi x 72 dpi) only to create TIFF containers.

 

2. Quick workflow: tiffPack's workflow goes as follows.

 

  1. Drag and drop one or more image files onto the dropbox at the top-right corner.  Make sure that a file name doesn't contain a high-resolution mark (@2x, @3x).
  2. Click on the Create button at the top.

 

3. Selecting files: When you first launch tiffPack, you'll see an introduction window, giving you a quick tour over how it works.  (See Screenshot 1-01.)  You can click on the right navigation button to turn over pages.

Let's first select and open image files.  Supported formats are BMP, GIF, JPEG, JPEG 2000, PDF, PNG, PSDF, TIFF (no container).  Just drag and drop ones onto the dropbox at the top-right corner.  (See Screenshot 1-02.)  If you do, tiffPack will list them below.  You can also choose Open Files under File to select and open one or more image files with the open-file panel.

The file list has four columns.  The first column shows a thumbnail of each file.  The second column shows the resolutions (dot per inch) of each file.  The third column lists number of pixels.  And the last column shows file paths.

Notice that there's a counter in blue located at the bottom-right corner.  (See Screenshot 1-03.)  It indicates the number of acceptable files, out of which tiffPack can create TIFF container files.  Even if you have one or more files listed, it's possible that this counter shows 0, which means that you have no file with which to create a TIFF container file.

Also notice that there's a toggle control with two buttons at the bottom-left corner.  If you want to remove any of files, first, select one in the list.  Then click on the - button of the toggle control.  Then you will be prompted for confirmation.  (See Screenshot 1-04.)  You can also choose Remove File under File for the same purpose.  Similarly, if you click on the -- button or choose Remove All Files under File, you can remove all files in the list.  And you will be prompted for confirmation in this case as well.  (See Screenshot 1-05.)

 

4. Acceptable and not-acceptable image files: We already know which graphic format tiffPack can read, which doesn't mean that the application will accept all files of supported formats.  The following is a list of rules.

 

  • tiffPack does not read a file whose name contains a high-resolution mark (@2x, @3x): Screenshot 1-06 shows a case where one has dragged and dropped a PNG file onto the drop box.  The file name is 001_bible_book_religion_god@2x.png.  tiffPack won't even list this file.  The status message shown at the bottom of the window says that you need to remove a high-resolution mark.  The reason why this application rejects files with a high-resolution mark is complicated.  For more information, click here.

  • A file must have precise resolutions of 72 dpi x 72 dpi: In reference to Screenshot 1-07, the resolutions of the second file are 96 dpi x 96 dpi.  If a file has resolutions other than 72 dpi x 72 dpi, the text color will turn red.  If you use an Adobe software product to create image files, you should be careful because you can often end up with resolutions of 28.35 pixels/cm or 72.01 pixels/inch even when specify 72 dpi x 72 dpi.

  • The pixel width and height must be even numbers: tiffPack uses your image to create a non-Retina image.  So the width and height number must be divisable by 2.  If either is an odd number, a size will appear in red.  (See Screenshot 1-08.)

 

  • A TIFF file must not be a package: What this application does is to create TIFF packages.  A TIFF container file can contain multiple images.  So tiffPack won't accept a TIFF container file.

 

5. Creating TIFF packages: When you are ready to create TIFF packages, all you have to do is click on the Create button at the top.  If it's grayed out, that's because tiffPack has no acceptable file to work with.  So the counter at the bottom-right corner should indicate zero.  (See Screenshot 1-09.)  If a path appears in red, that's because the application cannot locate the said file at the original location.  Screenshot 1-10 in turn shows that the counter is 12.  So the Create button is not grayed out.

Once you click on the Create button, you will be first prompted to select a folder or a volume where to save TIFF container files.  (See Screenshot 1-11).  If necessary, click on the New Folder button to create a new folder.  You don't have to worry about existing files being overwritten.  If tiffPack finds a file with the same name at the designated export path when creating a TIFF package, it will automatically append an underscore (_) plus a number to the original file name.  Anyway, when you select a destination folder, click on the Open button at the bottom-right corner of the select-folder panel or press the RETURN key.  And a window sheet with a progress wheel will appear.  (See Screeshot 1-12.)

Screenshot 1-13 shows the result of creating TIFF packages out of 12 PNG files.  If you want to check the package contents of a TIFF container file, you can use Preview.  Make sure you click on the disclosure button to see all images within the same container.  (See Screenshot 1-14.)
