This tool offers three ways to adjust the images – warping, blending, masking, black level and HSG. To switch between the functions, use the function tabs at the right top corner of the main workspace.

Image warping is used to make an image look visually correct when it is projected onto a non-planar screen.
Use the settings on the WARP page to change the image shape.

Function tab – WARP

Warping an image
Complete following steps to warp an image.

1. Choose a projector by clicking on its layout frame or choose it from the Layer tab.
2. At the Test Pattern toolbar, select the grid test pattern on projection.
3. At the Line field, select the line warping style from Liner or Curve according to the screen type.

4. At the Grid Point field, select the number of grids on the screen. Start with a minimal number of grids (2×2) and gradually increase the number when adjusting. Decreasing the grid number during adjustment will erase some of points setting.
5. At the Test Pattern toolbar, click the ALIGN button to align the test pattern lines with the grid points.
6. At the Move Pixel field, adjust the slider or enter a value to set the number of pixels that the selected point moves each time. Shortcuts: Press Ctrl + Up arrow to increase the pixels, or Ctrl + Down arrow to decrease the pixels.
7. Select the points you want to move. The chosen ones turn to orange.
   

   	Select a single point – Click the point or use the W, A, S, D keys to select a point
   	Select all points on a line – Place the mouse cursor anywhere on the line, and press Ctrl + V to choose a vertical line, or Ctrl + H for a horizontal line.
   	Select all points inside a region – Click and drag the cursor to select a region, and release the mouse to select all the points inside.

8. To warp the image, click and drag the grid points to move them, or use the keyboard arrow keys.
   

   Note: To make the warp easier, start with the outer area of the screen, and then move to the center area. As shown in the left image, adjust the red points first, and then move the blue ones.

9. Click Preview to see the warping of projection content, then click Preview again to return to the test pattern.
10. To Clear the warp setting, as the function tab, click RESET
11. To save the settings to the projector memory, at the top toolbar, click Save. The setting is saved to the Save Location selected.

Warping for image blending
When performing edge blending on two adjacent images, slightly change the shape of the overlapped area helps align the two images more precisely. In the example below, two projectors are placed side by side, and warping the overlapped edges of the images helps achieve a better edge alignment.

1. For better alignment manually, set two test patterns with the same number of grid lines, but different grid line color.
2. Adjust the warp control points for grid line alignment on overlapped area.

For example, point A of left projection is moved down to align the top line of right projection, and point B of right projection is movd down to align the bottom line of left projection.

Warp for edge blending

Note: To achieve the best result, it is suggested warping the image which is slightly larger. Also, adhere to
the rule of adjusting the outer points first, and then moving to the inner points.

Image blending is an image process to merge two or more partial images to a complete image. Use the
settings on the BLENDING page to blend the images.

Function tab – BLEND

Complete following steps to blend two adjacent image.

1. Choose a projector by clicking on its layout frame or choose one from the Layer tab. After being selected, the projector frame turns to light blue.
2. At the Test Pattern toolbar, set up the grid test patterns for the projectors. It’s suggested setting the two test pattern with the same number of lines, but different line color.
3. At the WARP tab, set up the line number and color of Overlap Align for each projector. On the overlapped area, Overlap Align draws marking lines as guides to help align the edges.

4. Select a projector, and click on the overlapped edge.

   Setup the blend edge

5. At the pop-up dialog, set up the blending edge
   • Switch on the Enable toggle button to enable the blending effect.
   • At the Overlap field, set the overlap width for blending by image percentage or pixel value. The percentage and pixel value is based on the projection resolution.
   • Adjust the Gamma setting to change the inflection and gradient of gamma curve.
   • Click OK to apply the blending setting to the edge.
6. Enable the blending effect, the selected edge is applied with a gradient effect.
7. Click Preview To view the results of the current adjustment, at the top toolbar, click Preview to project an image. Click Preview again to return to the test pattern.
8. Repeat step 4 to 8 on the other projector to setup its overlapped edge.
9. To Clear the warp setting of the chosen projector, at the function tab, click RESET.
10. To save the settings to the projector memory, at the top toolbar, click Save. The setting is saved to the Save Location selected.

After blending two images, the overlapped area may appear brighter than the rest of the image when projecting dark images.

Function tab – BLACK

To uniform the color performance, adjust the color of the non-overlapped area and the black border to make them look like the same with the overlapped area.

Black Level Areas

Note : Make sure that the black level adjustment is under dark field for good observation of black level variation.
Complete following steps to adjust the black level:

1. Switch to the Black Level function tab. The test pattern automatically changes to the black background.
2. Choose a projector by clicking on its layout frame or choose one from the Layer tab. After being selected, the projector frame turns to light blue.
3. Set the Move Pixel by adjustment the slider or enter a value. The value is the pixel number
   the control point moves each time when using the keyboard arrow keys.
4. Select the Grid Point value. The grid points control the adjustment of black level area for edge alignment with adjacent overlap area, up to 32 points adjustment for each black level area.
   Grid Point

   	Note: Start with 4 grid point number for the adjustment and increase the points gradually.

5. Set Move Pixel to control the movement for accurate alignment of adjacent black level area, user can set the value accordingly.
6. Select adjustment areas using the control points. You can select two areas to adjust, one for the non-overlapped area, and one for the black border.
   • Click on the point you want to move.
   • Drag the selected point to change its position on the canvas, or use the keyboard arrow keys.
