Hi together, To give a little status report about my recent improvements of the WMS layer stuff:
- Introduction of a factory model that handles different formats (mime-types) more clearly and abstract. This helps to handle the result streams coming from the HTTP responses. e.g images/svg+xml needs some XML parsing, images/png can be processed by javax.imageio.ImageIO - Usage of javax.imageio.ImageIO in case of bitmap images. If things like JAI ImageIO is installed a wider range of bitmap types are supported. - Usage of the Apache Common's HttpClient [1]. This enables better HTTP handling: persistent connections, queueing, limiting number of connections to servers, performing better with multiple Threads (pooling) and so on. It also enables us to use authentication, SSL, proxies. This may be of interest when connecting to protected servers. I will suspend my further development on this stuff till the unstable/development branch comes into existence. I don't want to commit it to the stable branch, because there are questions to talk about, improving the GUI e.g. If several mime-types are available I don't think that it is a bright idea to select it by internal 'magic'. Please let me, how and when I should proceed. I do this WMS stuff in my free time, so I have no time to waste it for things that went to the nirvana of cool but unpublished software. I've done to much of this in the past. Kind regards, Sascha [1] http://jakarta.apache.org/commons/httpclient/ Sunburned Surveyor schrieb: > Sascha, > > I agree with your comments.
