OpenGL ES antialiasing with rendering using GL_LINES

I am struggling to render smooth lines using GL_LINES.
I have borrowed the MultisampleConfigChooser from the following link: MultisampleConfigChooser.java
It seemed to find the multisample configuration without any errors.
Here is the code I use to render the lines on the screen:
GLES20.glUseProgram(this.lineDrawProgram);
GLES20.glEnableVertexAttribArray(mPositionHandle);
GLES20.glVertexAttribPointer(
mPositionHandle, 2,
GLES20.GL_FLOAT, false,
6*4, linesData);
linesData.position(2);
GLES20.glEnableVertexAttribArray(mColorHandle);
GLES20.glVertexAttribPointer(
mColorHandle, 4,
GLES20.GL_FLOAT, false,
6*4, linesData);
linesData.position(0);
GLES20.glUniformMatrix4fv(mMVPMatrixHandle, 1, false, matrix, 0);
GLES20.glDrawArrays(GLES20.GL_LINES, 0, this.numLines*2);
GLES20.glDisableVertexAttribArray(mPositionHandle);
GLES20.glDisableVertexAttribArray(mColorHandle);
Blending is enabled with GLES20.GL_SRC_ALPHA, GLES20.GL_ONE_MINUS_SRC_ALPHA.
One more mention is that I am drawing the lines to a texture which is bound to an FBO as a color attachment. I have not added any extra code to enable multisampling for the FBO.
Here is the code I use to setup the FBO and texture:
int[] fbo = new int[1];
int[] tex = new int[1];
enGLES20.glGenTextures(1, tex, 0);
GLES20.glGenFramebuffers(1, fbo, 0);
GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, tex[0]);
GLES20.glTexImage2D(GLES20.GL_TEXTURE_2D, 0,GLES20.GL_RGBA, this.width, this.height, 0,GLES20.GL_RGBA, GLES20.GL_UNSIGNED_BYTE, null);
GLES20.glTexParameteri(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_NEAREST);
GLES20.glTexParameteri(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_NEAREST);
GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, 0);
GLES20.glBindFramebuffer(GLES20.GL_FRAMEBUFFER, fbo[0]);
GES20.glFramebufferTexture2D(GLES20.GL_FRAMEBUFFER, GLES20.GL_COLOR_ATTACHMENT0, GLES20.GL_TEXTURE_2D, tex[0], 0);
GLES20.glBindFramebuffer(GLES20.GL_FRAMEBUFFER, 0);
The resulting lines still look like crap:
Please help me get these lines to look smooth.
BTW there are many different small lines in the screenshot, no curved lines or anything exotic.

Send shadow map to shader in OpenGL

I am trying to implement shadow-mapping in my scene, but all I get is zeros in my fragment shader when I call texture() (I've tested it with == 0.0). My question: Am I sending the depth texture to the shader correctly?
Here is my fragment shader code:
bool getShadow() {
vec4 lightProjPositionScaled = lightProjPosition/lightProjPosition.w;
vec2 texCoords = lightProjPositionScaled.xy*0.5 + 0.5; // bias
return lightProjPositionScaled.z + 0.0005 > texture(shadowMap, texCoords).x;
}
Here is my relevant java codeInit (edited due to BDL's comment)
gl.glEnable(GL2.GL_TEXTURE_2D);
// generate stuff
IntBuffer ib = IntBuffer.allocate(1);
gl.glGenFramebuffers(1, ib);
frameBuffer = ib.get(0);
ib = IntBuffer.allocate(1);
gl.glGenTextures(1, ib);
shadowMap = ib.get(0);
gl.glBindFramebuffer(GL2.GL_FRAMEBUFFER, frameBuffer);
gl.glBindTexture(GL2.GL_TEXTURE, shadowMap);
gl.glTexImage2D(GL2.GL_TEXTURE_2D, 0, GL2.GL_DEPTH_COMPONENT, 1024, 1024, 0, GL2.GL_DEPTH_COMPONENT, GL2.GL_FLOAT, null);
gl.glDrawBuffer(GL2.GL_NONE);
gl.glReadBuffer(GL2.GL_NONE);
gl.glBindFramebuffer(GL2.GL_FRAMEBUFFER, 0);
// prevents 'shadow acne'
gl.glPolygonOffset(2.5f, 0);
// prevents multiple shadows
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_WRAP_S, GL2.GL_CLAMP_TO_EDGE);
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_WRAP_T, GL2.GL_CLAMP_TO_EDGE);
// prevents (or expects!!!) pixel-y textures
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_MIN_FILTER, GL2.GL_NEAREST);
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_MAG_FILTER, GL2.GL_NEAREST);
// store one value in all four components of pixel
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_DEPTH_TEXTURE_MODE, GL2.GL_INTENSITY);
Display (1st pass, for shadows):
// render shadows
gl.glUseProgram(shadowProgram);
gl.glUniformMatrix4fv(lightMatrixLocShadow, 1, false, lightMatrix.getMatrix(), 0); // yep (haha change viewMatrix -> lightMatrix)
gl.glUniformMatrix4fv(projMatrixLocShadow, 1, false, projMatrix.getMatrix(), 0);
gl.glBindFramebuffer(GL2.GL_FRAMEBUFFER, sha.frameBuffer);
gl.glViewport(0, 0, 1024, 1024);
gl.glClear(GL2.GL_DEPTH_BUFFER_BIT);
renderScene(gl, sunMatrix);
gl.glCopyTexImage2D(GL2.GL_TEXTURE_2D, 0, GL2.GL_DEPTH_COMPONENT, 0, 0, 1024, 1024, 0);
gl.glBindFramebuffer(GL2.GL_FRAMEBUFFER, 0);
Display (2nd pass, for rendering the scene):
// render display (regular)
gl.glUseProgram(displayProgram);
gl.glDrawBuffer(GL2.GL_FRONT);
gl.glReadBuffer(GL2.GL_FRONT);
gl.glUniformMatrix4fv(viewMatrixLoc, 1, false, viewMatrix.getMatrix(), 0);
gl.glUniformMatrix4fv(projMatrixLocDisplay, 1, false, projMatrix.getMatrix(), 0);
gl.glUniformMatrix4fv(lightMatrixLocDisplay, 1, false, lightMatrix.getMatrix(), 0);
gl.glUniform4fv(sunPositionLoc, 1, sunWorldPosition, 0); // send sun's position to shader
gl.glUniform1f(sunBrightnessLoc, sunBrightness);
gl.glUniform1i(shadowMapLoc, 0);
gl.glViewport(0, 0, screenWidth, screenHeight);
// day-night cycle
float[] color = SkyManager.getSkyColor(time);
gl.glClearColor(color[0], color[1], color[2], 1);
gl.glClear(GL2.GL_COLOR_BUFFER_BIT | GL2.GL_DEPTH_BUFFER_BIT);
gl.glActiveTexture(GL2.GL_TEXTURE0);
gl.glBindTexture(GL2.GL_TEXTURE_2D, sha.shadowMap);
renderScene(gl, sunMatrix);
Another strange outcome is that only fragments on the z=0 plane relative to the light matrix (the light's rotating, and the plane rotates with it) are lit. All other fragments, behind and in front of the light, are shadowed.

One issue was with the line gl.glBindTexture(GL2.GL_TEXTURE, shadowMap);
I was binding the texture to GL_TEXTURE instead of GL_TEXTURE_2D.

Get screenshot of startmenu

I am using bitblt to to capture a window. If the aero theme is enabled, The background of the captured image is black. If I disable the DWM and capture the window then the captured image is very good.
Here is part of my code.
HDC hdcMemDC = GDI32.INSTANCE.CreateCompatibleDC(desktopDC);
HDC windowDC = User32.INSTANCE.GetDC(window);
HWND window= User32Extra.INSTANCE.FindWindow(null, "Start menu");
GDI32Extra.INSTANCE.BitBlt(hdcMemDC, 0, 0, width, height, desktopDC, 0, 0, WinGDIExtra.SRCCOPY );
GDI32Extra.INSTANCE.BitBlt(hdcMemDC,windowBounds.left, windowBounds.top, windowWidth, windowHeight, windowDC, windowBounds.left+windowBounds1.right-windowBounds.right+(windowExtraGap/2), windowBounds.top+windowBounds1.bottom-windowBounds.bottom+(windowExtraGap/2), WinGDIExtra.SRCCOPY);
How to capture the start Menu with proper background?
Are there any other methods to get the proper image of aero window?

use desktop DC and cut to window
RECT rc, rc2;
GetClientRect(hWnd, &rc);
GetWindowRect(hWnd, &rc2);
int width = rc2.right - rc2.left;
int height = rc2.bottom - rc2.top;
HDC hdcScreen = GetDC(NULL); //!!!! Get desktop DC
HDC hBmpFileDC = CreateCompatibleDC(hdcScreen);
HBITMAP hBmpFileBitmap = CreateCompatibleBitmap(hdcScreen, width, height);
HBITMAP hOldBitmap = (HBITMAP)SelectObject(hBmpFileDC, hBmpFileBitmap);
BitBlt(hBmpFileDC, 0, 0, width, height, hdcScreen, rc2.left, rc2.top, SRCCOPY | CAPTUREBLT);
HGDIOBJ prev = SelectObject(hBmpFileDC, hOldBitmap);
SaveBitmap(szLogFilename, hBmpFileBitmap);
DeleteDC(hBmpFileDC);
DeleteObject(hBmpFileBitmap);
another variant
RECT rc;
GetClientRect(hWnd, &rc);
int width = rc.right - rc.left;
int height = rc.bottom - rc.top;
HDC hdcScreen = GetDC(hWnd);
////////////////////////////
PrintWindow(hWnd, hdcScreen, 0);
PrintWindow(hWnd, hdcScreen, PW_CLIENTONLY);
////////////////////////////
HDC hBmpFileDC = CreateCompatibleDC(hdcScreen);
HBITMAP hBmpFileBitmap = CreateCompatibleBitmap(hdcScreen, width, height);
HBITMAP hOldBitmap = (HBITMAP)SelectObject(hBmpFileDC, hBmpFileBitmap);
BitBlt(hBmpFileDC, 0, 0, width, height, hdcScreen, 0, 0, SRCCOPY | CAPTUREBLT);
HGDIOBJ prev = SelectObject(hBmpFileDC, hOldBitmap);
SaveBitmap(szLogFilename, hBmpFileBitmap);
DeleteDC(hBmpFileDC);
DeleteObject(hBmpFileBitmap);
before call any capture method I call PrintWindow. It acts window to redraw itself. And as a result screen capture will have correct picture. The most stable result I got with double call of PrintWindow.

Java SWT ScrolledForm Background Color

I am having an issue with a ScrolledForm. I am trying to change the background and foreground colour for a Label defined in the body of the ScrolledForm, however it doesn't seem to be working.
In my code snippet, I would like lblWhat to have a black background and white foreground.
Here is my code snippet:
ScrolledForm scrldfrmNewScrolledform = formToolkit.createScrolledForm(parent);
scrldfrmNewScrolledform.setLayoutData(gd);
scrldfrmNewScrolledform.setFont(SWTResourceManager.getFont("Segoe UI", 16, SWT.NORMAL));
scrldfrmNewScrolledform.setBackground(SWTResourceManager.getColor(SWT.COLOR_WIDGET_BACKGROUND));
scrldfrmNewScrolledform.getBody().setBackground(SWTResourceManager.getColor(SWT.COLOR_WHITE));
scrldfrmNewScrolledform.setImage(SWTResourceManager.getImage(EPRForm.class, "/icons/AFCCEPR.png"));
scrldfrmNewScrolledform.setBounds(10, 10, 430, 280);
formToolkit.paintBordersFor(scrldfrmNewScrolledform);
scrldfrmNewScrolledform.setText("ePR (electronic Purchase Request)");
Label lblName = new Label(scrldfrmNewScrolledform.getBody(), SWT.NONE);
lblName.setBounds(10, 21, 55, 15);
formToolkit.adapt(lblName, true, true);
lblName.setText("Name:");
text = new Text(scrldfrmNewScrolledform.getBody(), SWT.BORDER);
text.setBounds(71, 15, 269, 21);
formToolkit.adapt(text, true, true);
Label lblWhat = new Label(scrldfrmNewScrolledform.getBody(), SWT.None);
lblWhat.setBounds(10, 35, 100, 15);
lblWhat.setBackground(SWTResourceManager.getColor(SWT.COLOR_BLACK));
lblWhat.setForeground(SWTResourceManager.getColor(SWT.COLOR_WHITE));
formToolkit.adapt(lblWhat, true, true);
lblWhat.setText("What do you want?");
Label lblItem = new Label(scrldfrmNewScrolledform.getBody(), SWT.None);
lblItem.setBounds(10, 55, 100, 15);
formToolkit.adapt(lblItem, true, true);
lblItem.setText("Items to be Ordered*");
txtItems = new Text(scrldfrmNewScrolledform.getBody(), SWT.BORDER | SWT.WRAP | SWT.H_SCROLL | SWT.V_SCROLL | SWT.CANCEL);
txtItems.setBounds(10, 60, 338, 84);
formToolkit.adapt(txtItems, true, true);

You seem to be using FormToolkit. The FormToolkit.adapt method forces the control colors to the colors set for the form (normally white background and black text).
For a single control you could try calling setBackground and setForeground after the adapt call.
You can set the colors for the entire form with
FormColors colors = toolkit.getColors();
colors.setBackground(...);
colors.setForeground(...);

Java Graphics2D Path2D Simplify or call from separate class

I'm wondering if I can clean up my code somehow using a list or call it from another class because I have a lot of exact Path2D coordinates just cluttering my paintComponent.
public void paintComponent(Graphics g)
{ Graphics2D g2=(Graphics2D)g;
super.paintComponent(g2);
//Background
Rectangle background = new Rectangle(0,0,getWidth(),getHeight());
Color skyBlue = new Color(135,206,235);
g2.setColor(skyBlue);
g2.fill (background);

Whatever you do I would
create the Path2D objects outside of the paintComponent() method.
add each Path2D object to an ArrayList
in the paintComponent() method you can iterate through the ArrayList to paint each Path2D
Or another approach is to just have a method that:
creates each Path2D object when the class is created
then you paint the Path2D object to a BufferedImage
now that you have a BufferedImage you can create an ImageIcon and Just use a JLabel in you app and you don't need the custom panel.

Heres 2 options I would consider for cleaning up the pathing.
Use SVG, one library I know is Batik found at: http://xmlgraphics.apache.org/batik/
Once I did a project where the paths I needed would be created in photoshop then exported to Illustrator. The file format was each action was line delineated, each line was space delineated and consisted of a set of points with the last entry the command name. Here was a sample input.
10 10 m
15 15 l
10 10 12 12 v
As you can see you just read the file, create your path and do an if test for the last letter on the line and use the appropriate command with for the points. Of course you can make up your own format or procedures but it sure was nice using photoshop for me :)
