Body
OK, here is the solution I ended up with. <ol> <li>I transformed all my array[][] into a BufferedImage object <pre><code>static BufferedImage BImageFrom2DArray(float data[][]) { int width = data.length; int height = data[0].length; BufferedImage myimage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); for (int x = 0; x < width; x++) { for (int y = 0; y < height; y++) { int value = (int) ((1f - data[x][y]) * 255f); myimage.setRGB(y, x, (value << 16) | (value << 8) | value); } } return myimage; } </code></pre></li> <li>Applied the affine transformation using AffineTransformOp with interpolation bicubic <pre><code> AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_BICUBIC); BufferedImage im_transformed = op.filter(im_src, null); </code></pre></li> <li>Transformed back the BufferedImage object into array[][]: <pre><code> static float[][] ArrayFromBImage(BufferedImage bimage, int width, int height) { int max_x = bimage.getWidth(); int max_y = bimage.getHeight(); float[][] array = new float[width][height]; for (int x = 0; x < width; x++) { for (int y = 0; y < height; y++) { float red, alpha, value; int color; if (x >= max_x || y >= max_y) { array[y][x] = 0; } else { color = bimage.getRGB(x, y); alpha = (color >> 24) & 0xFF; red = (color >> 16) & 0xFF; value = 1f - red / 255; if (alpha == 0) { array[y][x] = 0; } else { array[y][x] = value; } } } } return array; } </code></pre></li> </ol>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
