There is a 64KB file size limitation. However in order to provide the best possible mobile user experience, we strongly recommend that you optimize your content. Category Top10. Do you have an example directory structure that content developers should use?
We do not impose a specific directory structure when creating content with the Plazmic Content Developer’s Kit. However, make sure that you use relative URLs when linking to other scenes, images, or sounds, and that content creation environment is the same as the content deployment environment. This guideline enables you to move entire directories from one location to another. Category Top11. How do I optimize my content, generally?
- Use small images (minimum resolution and color depth)
- Use polygons wherever large amounts of color are required, and images where complex graphical elements required
- Rectangle
is your friend - Polygons
are your friends too! - Reduce number of images in your content
- Reduce the number of colors your images
12. How do I get content out of Composer into a format that the Media Engine understands?
Please review the Plazmic Content Developer's Kit User Guide documentation and the Composer User Guide documentation for a detailed explanation of the content creation process. Here are the general steps for exporting content from Composer into a format the Media Engine understands:- 1. Export your scene out of Composer as .svg, pme or .pmb format. (File > Export ).
- If you export your content in SVG format, you must transcode it into .pme or .pmb format.
- 2. To view .pme or .pmb content, perform the following actions:
- a. Place your content on a web application server.
- b. Edit the web application server’s mime types to enable the BlackBerry browser to recognize the .pme or .pmb content.
- 3. Use the BlackBerry browser on your BlackBerry wireless handheld to view your content.
13. How do I optimize content when exporting from Composer?
To reduce the size of your content that is exported from Composer, keep in mind the following attributes produce an image for each frame of animation:- animated rotation of images
- animated scaling of images
- animated filters and effects
- animated opacity
- animated non-handheld font attributes (for example color, skew, or size,)
