Border Padding

[zhuangX2]

Greetings. I'm currently using a Windows 7 Visual Style called, TAPEK.

Tapek by =kiko11 on deviantART

It uses invisible borders, and requires disabling of the blur effect to look proper. The problem is that when I snap my windows to the grid to tile them manually, there will be spaces between the edge of the window and the edge of my screen, because of these invisible borders. I've found that I can reduce the size of these spaces by reducing the border padding, through right clicking my desktop > Personalize > Window Colour > Advanced Appearance Settings. Even at 0, the lowest border padding setting attainable through this method, some space is still visible.

My question is, how do I make the border padding even lower, in the negative values?

I am not sure if you can get a negative border padding setting, but I can explain to you what's going on with that theme.
As you can see from the screenshot you will see a light gray or shadow on the sides of the image that is your invisible border, the only way I can see to remove the gap between your open window and or screen edge would be to edit those images by adding more solid color to the outside but then you will lose your thin border (Second screenshot shows where I added some color to just the side images with the padding set a zero, The gaps you still see at the top and bottom of the window are from the top and bottom image that has not been edited yet.)
Note: There are four images for the border the top the two sides and the bottom I put the images on a white background so you could see what they look like.
