From 01c709ff0e81ddd84e3bc78ec180a53587ec855c Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Tue, 9 Sep 2014 19:58:47 +0200 Subject: Don't utilize glPixelStorei's PACK/UNPACK IMAGE_HEIGHT and SKIP_IMAGES for Desktop GL < 1.2, avoiding GL-Error Commit fc1e98790a02b4fa7922f3cdd9d437f87d7c99e5 added handling of PACK/UNPACK IMAGE_HEIGHT and SKIP_IMAGES in GLPixelStorageModes. However, it has been overseen that the four states are not available in OpenGL 1.1. Adding exclusion of the same if desktop GL < 1.2 and hence avoiding GL errors. Same applies to GLBuffers.sizeof(..) method. --- .../classes/com/jogamp/opengl/util/GLBuffers.java | 5 +++-- .../com/jogamp/opengl/util/GLPixelStorageModes.java | 19 +++++++++++++------ 2 files changed, 16 insertions(+), 8 deletions(-) (limited to 'src') diff --git a/src/jogl/classes/com/jogamp/opengl/util/GLBuffers.java b/src/jogl/classes/com/jogamp/opengl/util/GLBuffers.java index 44be29957..e3069c29b 100644 --- a/src/jogl/classes/com/jogamp/opengl/util/GLBuffers.java +++ b/src/jogl/classes/com/jogamp/opengl/util/GLBuffers.java @@ -46,6 +46,7 @@ import javax.media.opengl.GL2; import javax.media.opengl.GL2ES2; import javax.media.opengl.GL2ES3; import javax.media.opengl.GL2GL3; +import javax.media.opengl.GLContext; import javax.media.opengl.GLES2; import javax.media.opengl.GLException; @@ -376,7 +377,7 @@ public class GLBuffers extends Buffers { rowLength = glGetInteger(gl, GL2ES3.GL_PACK_ROW_LENGTH, tmp); skipRows = glGetInteger(gl, GL2ES3.GL_PACK_SKIP_ROWS, tmp); skipPixels = glGetInteger(gl, GL2ES3.GL_PACK_SKIP_PIXELS, tmp); - if (depth > 1) { + if (depth > 1 && gl.getContext().getGLVersionNumber().compareTo(GLContext.Version120) >= 0 ) { imageHeight = glGetInteger(gl, GL2GL3.GL_PACK_IMAGE_HEIGHT, tmp); skipImages = glGetInteger(gl, GL2GL3.GL_PACK_SKIP_IMAGES, tmp); } @@ -387,7 +388,7 @@ public class GLBuffers extends Buffers { rowLength = glGetInteger(gl, GL2ES2.GL_UNPACK_ROW_LENGTH, tmp); skipRows = glGetInteger(gl, GL2ES2.GL_UNPACK_SKIP_ROWS, tmp); skipPixels = glGetInteger(gl, GL2ES2.GL_UNPACK_SKIP_PIXELS, tmp); - if (depth > 1) { + if (depth > 1 && gl.getContext().getGLVersionNumber().compareTo(GLContext.Version120) >= 0 ) { imageHeight = glGetInteger(gl, GL2ES3.GL_UNPACK_IMAGE_HEIGHT, tmp); skipImages = glGetInteger(gl, GL2ES3.GL_UNPACK_SKIP_IMAGES, tmp); } diff --git a/src/jogl/classes/com/jogamp/opengl/util/GLPixelStorageModes.java b/src/jogl/classes/com/jogamp/opengl/util/GLPixelStorageModes.java index 52612d224..cef49d388 100644 --- a/src/jogl/classes/com/jogamp/opengl/util/GLPixelStorageModes.java +++ b/src/jogl/classes/com/jogamp/opengl/util/GLPixelStorageModes.java @@ -171,7 +171,7 @@ public class GLPixelStorageModes { */ public final void resetPack(final GL gl) { // Compared w/ ES2, ES3 and GL3-core spec - gl.glPixelStorei(GL.GL_PACK_ALIGNMENT, 4); // es2, es3, gl3 + gl.glPixelStorei(GL.GL_PACK_ALIGNMENT, 4); // es2, es3, gl3 if( gl.isGL2ES3() ) { gl.glPixelStorei(GL2ES3.GL_PACK_ROW_LENGTH, 0); // es3, gl3 gl.glPixelStorei(GL2ES3.GL_PACK_SKIP_ROWS, 0); // es3, gl3 @@ -179,8 +179,10 @@ public class GLPixelStorageModes { if( gl.isGL2GL3() ) { gl.glPixelStorei(GL2GL3.GL_PACK_SWAP_BYTES, GL.GL_FALSE); // gl3 gl.glPixelStorei(GL2GL3.GL_PACK_LSB_FIRST, GL.GL_FALSE); // gl3 - gl.glPixelStorei(GL2GL3.GL_PACK_IMAGE_HEIGHT, 0); // gl3 - gl.glPixelStorei(GL2GL3.GL_PACK_SKIP_IMAGES, 0); // gl3 + if( gl.getContext().getGLVersionNumber().compareTo(GLContext.Version120) >= 0 ) { + gl.glPixelStorei(GL2GL3.GL_PACK_IMAGE_HEIGHT, 0); // gl3, GL_VERSION_1_2 + gl.glPixelStorei(GL2GL3.GL_PACK_SKIP_IMAGES, 0); // gl3, GL_VERSION_1_2 + } } } } @@ -242,16 +244,21 @@ public class GLPixelStorageModes { */ public final void resetUnpack(final GL gl) { // Compared w/ ES2, ES3 and GL3-core spec - gl.glPixelStorei(GL.GL_UNPACK_ALIGNMENT, 4); // es2, es3, gl3 + gl.glPixelStorei(GL.GL_UNPACK_ALIGNMENT, 4); // es2, es3, gl3 if( gl.isGL2ES3() ) { gl.glPixelStorei(GL2ES2.GL_UNPACK_ROW_LENGTH, 0); // es3, gl3 gl.glPixelStorei(GL2ES2.GL_UNPACK_SKIP_ROWS, 0); // es3, gl3 gl.glPixelStorei(GL2ES2.GL_UNPACK_SKIP_PIXELS, 0); // es3, gl3 - gl.glPixelStorei(GL2ES3.GL_UNPACK_IMAGE_HEIGHT, 0); // es3, gl3 - gl.glPixelStorei(GL2ES3.GL_UNPACK_SKIP_IMAGES, 0); // es3, gl3 if( gl.isGL2GL3() ) { + if( gl.getContext().getGLVersionNumber().compareTo(GLContext.Version120) >= 0 ) { + gl.glPixelStorei(GL2ES3.GL_UNPACK_IMAGE_HEIGHT, 0); // es3, gl3, GL_VERSION_1_2 + gl.glPixelStorei(GL2ES3.GL_UNPACK_SKIP_IMAGES, 0); // es3, gl3, GL_VERSION_1_2 + } gl.glPixelStorei(GL2GL3.GL_UNPACK_SWAP_BYTES, GL.GL_FALSE); // gl3 gl.glPixelStorei(GL2GL3.GL_UNPACK_LSB_FIRST, GL.GL_FALSE); // gl3 + } else { + gl.glPixelStorei(GL2ES3.GL_UNPACK_IMAGE_HEIGHT, 0); // es3, gl3, GL_VERSION_1_2 + gl.glPixelStorei(GL2ES3.GL_UNPACK_SKIP_IMAGES, 0); // es3, gl3, GL_VERSION_1_2 } } } -- cgit v1.2.3
