Save the DRAGRI content file.
Select [File]-[Save as Web Content] from the menu bar in the main window. A Save configuration dialog box will appear as shown in the figure. The fields are described below:
Enter the name of the destination directory for the file, or click [...] to display the file selection dialog box and select the directory in which to save the file.
To create a new directory, type "directory name" at the end of the path name.
If you click the [New] button, a dialog box for entering a directory name will appear. A new directory with the specified name will be created within the selected directory.

Example of block noise
In any case, even if the numerical value is increased, the image quality will not become better than that of the original material, and the file can become larger unnecessarily. Adjust the differential compression parameter with care.
You can set an expiration date for the content. After the expiration date, the content cannot be viewed. The format is yyyy-mm-dd.
You can make the expiration date unlimited by leaving this field blank.
This file contains the play data for the content. If you are creating a new content file, this box is already selected.
These items are usually used when existing content has been re-edited using dragri.txt.
If video, image or audio data have been added, or frame attributes of key frames or skip frames changed, or the number of frames changed as a result of a modification in frame reduction settings, the box is selected automatically. Usually, keep this as it is.
When you save a file with this box checked, a file named data.jar is created. This file aggregates all files except dragri.jar.
Since this file is compressed, download time can be saved when the file is viewed in a browser.
In some environments, you may not be able to access data.jar. In such a case, ordinary files are used instead. Accordingly, you should not delete the ordinary files even if you are using data.jar.
This is a program file for playing the content in a browser. The browser reads in this file and executes the program.
This program is common to all content files.
This is to specify whether to generate the Web page file, index.html.
If you select [File]-[Save webpage], the image of the current frame specified on the timeline is saved as a thumbnail of the file.
The thumbnail image is saved under the name of thumb.jpg in the directory specified for saving the thumbnail image.
This is to specify whether to view the created content with a browser after you have saved it.
All files required for playing the content are compressed into zip files.
They are saved under the name of "directory-name.zip" in the directory specified for saving the content.
Use this option when you want to upload the files to the Web server by FTP or attach the files to e-mail.
If the file size of the content is too large, downloading it takes a significant amount of time. Since large files will take up the memory available to a browser, the browser may not be able to play the content smoothly. A reasonable file size for the content is up to 500 kB. This is equivalent to about 50 frames with a frame size of 320 x 240 pixels.
Use the following methods to adjust the file size for optimum download.
If you decrease the values of [JPEG] and [Differential image compression] in [Image quality] when you save the Web page, this will reduce the file size.
The standard value for [JPEG] and [Differential image compression] is 75. However, if noise is noticeable when you check the content with a browser, increase the values slightly to get optimum image quality.
The more frames in the video, the smoother the movement but the larger the file size.
You can reduce the file size by reducing the number of frames.
The size of a video also greatly affects the file size.
When the size of a video is reduced, the file size also becomes smaller.
