.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a Catalyst View subclass which can handle rendering \s-1GD\s0 based 
image content.
.SH "CONFIG OPTIONS"
.IX Header "CONFIG OPTIONS"
.IP "\fIgd_image_type\fR" 4
.IX Item "gd_image_type"
This defaults to \f(CW\*(C`gif\*(C'\fR but should be the name of the method to call on the 
GD::Image instance in order to render the images.
.IP "\fIgd_image_render_args\fR" 4
.IX Item "gd_image_render_args"
This is an array ref of values to be passed as an argument to the GD::Image 
render method.
.IP "\fIgd_image_content_type\fR" 4
.IX Item "gd_image_content_type"
The default for this is built from the \f(CW\*(C`gd_image_type\*(C'\fR parameter, which in 
most cases will just work, but in some more specific rendering methods in 
GD::Image it will not and you will need to assign this explicitly.
.SH "METHODS"
.IX Header "METHODS"
.IP "\fBnew\fR" 4
.IX Item "new"
This really just handles consuming the configuration parameters.
.IP "\fBprocess\fR" 4
.IX Item "process"
This method will always look in the \f(CW\*(C`gd_image\*(C'\fR stash for an instance of 
GD::Image and it will then render and serve it according to the 
configuration setup.
.Sp
It is also possible to override the global configuration on a per-request 
basis by assigning values in the stash using the same keys as used in 
the configuration.
.SH "BUGS"
.IX Header "BUGS"
All complex software has bugs lurking in it, and this module is no 
exception. If you find a bug please either email me, or add the bug
to cpan-RT.
