Interface ImageRenderer

All Known Subinterfaces:

All Known Implementing Classes:

AbstractInteractiveImageRenderer, ItemStackImageRenderer, MissingItemRenderer, TextureImageRenderer

public interface ImageRenderer

This allows implementing custom image renderers.

Image renderers are used to draw custom areas in a manual page, defined as an image with a special URL, matching the prefix of a registered image provider. A renderer will then be used to draw something at the position of the image tag.

Built-in image renderers are item, block and tag.

Method Summary

Modifier and Type	Method and Description
int	getHeight() The height of the area this renderer uses.
int	getWidth() The width of the area this renderer uses.
void	render(int mouseX, int mouseY) Render the image, with specified maximum width.

Method Detail

getWidth

int getWidth()

The width of the area this renderer uses.

This is used to offset the OpenGL state properly before calling render(int, int), to correctly align the image horizontally.

Returns:

the width of the rendered image.

getHeight

int getHeight()

The height of the area this renderer uses.

This is used to offset the OpenGL state properly before calling render(int, int), as well as to know where to resume rendering other content below the image.

Returns:

the height of the rendered image.

render

void render(int mouseX,
            int mouseY)

Render the image, with specified maximum width.

This should render the image as is, the OpenGL state will be set up such that you can start drawing at (0,0,*), and render up to (getWidth,getHeight,*), i.e. translation and scaling are taken care of for you.

Parameters:

mouseX - the X position of the mouse relative to the element.

mouseY - the Y position of the mouse relative to the element.
