This PR aims to address the following issue: JDK-8088198 Exception thrown from snapshot if dimensions are larger than max texture size
In order to do that, it simply captures snapshots in multiple tiles of maxTextureSize^2 dimensions (or less, as needed), and then recomposes all the tiles into a a single image. Other than that, the logic used to do the actual snapshot is unchanged. Tests using the existing SnapshotCommon class have been added in a new file named Snapshot3Test under SystemTest/test/javafx/scene. These tests pass with the proposed fix, and fail without, throwing " java.lang.IllegalArgumentException: Unrecognized image loader: null" ------------- Commits: - 4bc44173: 8088198: Exception thrown from snapshot if dimensions are larger than max texture size Changes: https://git.openjdk.java.net/jfx/pull/68/files Webrev: https://webrevs.openjdk.java.net/jfx/68/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8088198 Stats: 142 lines in 2 files changed: 111 ins; 11 del; 20 mod Patch: https://git.openjdk.java.net/jfx/pull/68.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/68/head:pull/68 PR: https://git.openjdk.java.net/jfx/pull/68
