Functions

addCurlMesh

@Synchronized

fun addCurlMesh(mesh: CurlMesh)

Adds CurlMesh to this renderer.

getPageRect

fun getPageRect(page: Int): RectF?

Returns rect reserved for left or right page. Value page should be PAGE_LEFT or PAGE_RIGHT.

inverseTranslateX

fun inverseTranslateX(x: Float): Float

Inverse translates screen coordinates into view coordinates.

inverseTranslateY

fun inverseTranslateY(y: Float): Float

Inverse translates screen coordinates into view coordinates.

onDrawFrame

@Synchronized

open override fun onDrawFrame(gl: GL10?)

Draws curl meshes.

onSurfaceChanged

open override fun onSurfaceChanged(gl: GL10?, width: Int, height: Int)

Called once surface is created.

onSurfaceCreated

open override fun onSurfaceCreated(gl: GL10?, config: EGLConfig?)

Called once surface is created.

removeCurlMesh

@Synchronized

fun removeCurlMesh(mesh: CurlMesh): Boolean

Removes CurlMesh from this renderer.

setMargins

@Synchronized

fun setMargins(left: Int, top: Int, right: Int, bottom: Int)

Sets actual screen pixel margins.

setProportionalMargins

@Synchronized

fun setProportionalMargins(left: Float, top: Float, right: Float, bottom: Float)

Sets proportional margins or padding. Note: margins are proportional. Meaning a value of 0.1f will produce a 10% margin

setViewMode

@Synchronized

fun setViewMode(viewMode: Int)

Sets visible page count to one or two. Should be either SHOW_ONE_PAGE or SHOW_TWO_PAGES.

translate

fun translate(pt: PointF)

Translates screen coordinates into view coordinates.
