Image Producer

The image producer of a JMap project is used to produce images on demand for that project. These images are used for JMap Web applications. When a user works in JMap Pro, the image producer is not used because the data is transferred in vector format (except for photos).

Normally, the image producer’s settings do not need to be modified because the default configuration is adequate. The following table describes the settings of the image producer.

Memory settings
Maximum size	The maximum amount of memory allotted to the project’s image producer. This memory is used to store the project’s vector data in order to accelerate the production of images. For very large projects, this setting can be increased.
Memory usage	The amount of memory currently used. The left value varies depending on usage. The right value is the maximum amount of memory allocated to the image producer.
Usage peak	Maximum memory size reached since last JMap Server startup.
Memory release	Determines the percentage of memory to be released when the memory of the image producer is saturated.
Thread pool settings
Initial size	The number of threads determines the number of images that can be produced simultaneously.
Maximum size	If the number of threads increases due to high demand, this value limits the number of threads.
Pool usage	Number of threads currently used (left value) out of the maximum number allocated (right value).
Usage peak	Maximum number of threads reached since last JMap Server startup.
View wait timeout	The maximum period before an image request expires. This option is usually disabled.
