There are four types of metadata used in digital photo utilities:
All of these values can be used in text substitution in DPU utilities that do text substitution. Image MetadataBelow is a description of all the currently available image metadata tags. Not all cameras record all values, so some data may be missing from your pictures. In some cases, different brands of cameras use different EXIF values to record the values and DPU does its best to find the value using all available data. The Writable column defines whether or not the value can be edited using MetaEditor. The following tags are legal for the key word "image". Thus these work for key phrases of the form "{image tag}" where tag is one of the tags described in the table below.
Most modern digital cameras store images with JPEG or TIFF compression and include EXIF meta data. For more information about EXIF metadata, see EXIF 2.1 specification. Formatting Dates and TimesDates and times can have special formatting applied to them to allow them to be displayed exactly as you want. For Example, if you have an image taken August 17, 2000 at 4:32:32 pm you can generate the following date formats in Saver, MetaEdit or Caption. They will work with the OriginalDate, DigitizedDate or ModifiedDate fields.
Advanced Date formatting If none of the above formats suit your needs, you can construct your own format string from the characters below
Computer MetadataThe following tags are legal for the key word "computer". Thus these work for key phrases of the form "{computer tag}" where tag is one of the tags described in the table below.
DPU MetadataThe following tags are legal for the key word "DPU". Thus these work for key phrases of the form "{DPU tag}" where tag is one of the tags described in the table below.
File MetadataThe following tags are legal for the key word "File". Thus these work for key phrases of the form "{File tag}" where tag is one of the tags described in the table below.
Utility Specific MetadataWebGeneratorThe following tags are legal for the key word "Web" in HTML files which appear in web style folders used by WebGen. Thus these work for key phrases of the form "{Web tag}" where tag is one of the tags described in the table below. The use of these tags is for advanced users who have some knowledge of HTML.
Table GenerationOne of the more complex tags is the one for generating HTML code. It creates an HTML table by creating a table framework and creating a cell definition for each image in the web gallery.
A {web table...} key phrase may appear anywhere in any html page. It allows you to define an html table of rows and columns on a web page. A cell is created for each image. The number of of columns is determined by the first parameter, numColumns. If there are more than that number of images, they will be split up into rows that are numColumns wide. The second parameter is the cell definition. This html code will be inserted in each cell of the table. Text Substitutions will be applied to this html code. The html following html code will create a 4 column wide table of image titles with each title centered within its cell. {table 4 {<center>{image title}</center>}} The html following html code will create a 5 column wide table of thumbnails with titles and links to a pages named for each image. The alternate text for the thumbnail is set to the image description so that in most browsers a pop-up will appear with the text if {table 5 {<center><a href="{image name}.htm"><img src="{image thumbnail}"
alt="{image description}"><br>{image title}</a><br> </center>}} Image IterationImage Iteration is a general purpose method of iterating through all the images in the gallery to generate HTML code. It is very useful for generating HTML code for each image within a page, such as creating a list of images for scripts etc.
Given a drag and drop event with n images, the first item definition will have text substitution applied for the first 1 to n-1 images of of the drag and drop event. The second item definition will be applied only to the last image in the list. This allows for definitions like the one below: {web iterateImages {"{image name}.htm",} {"{image name}.htm"}} Given a list of images mypic1.jpg - mypic5.jpg, this text substitution will create the following HTML code: "mypic1.jpg, mypic2.jpg, mypic3.jpg, mypic4.jpg, mypic5.jpg" Note that the first four image names are followed by commas while the last one is not. This is made possible by "nth item definition" which does not include a comma. SaverThe following tags are legal for the key word "file" in file name definitions in the Saver. In order to save display space, these key phrases do not require the word file. Thus these work for key phrases of the form "{tag}" where tag is one of the tags described in the table below. The date referred to is calculated by looking up the EXIF digitized date. If this date is not available, the image file creation date is used.
