Skew |
||||||||
|
Skew gives fine tuning control over texture alignment within the frame.
There are two groups of Skew controls, Skew A and Skew B. Both
groups have independent controls for each frame side as indicated
by the small images between the sliders. Skew A moves the texture
along the direction of the frame edge and Skew B moves the texture
into and out from the center of the image as indicated by the small
images next to the Skew buttons.
Each control has a full range of 1000 steps and at maximum that moves the texture by exactly one tile. This means that the texture movement is proportional to texture size. What this gives you is single-pixel movement resolution for textures up to 1000 pixels height or width. For example a texture 250 pixels wide will move 1 pixel for every 4 steps of the A sliders, a texture 1000 pixels wide will move 1 pixel for each step of the A sliders and textures larger than 1000 pixels will move more than 1 pixel per step. Likewise the texture will move a number of pixels proportional to the texture height for the B sliders. Since the control range of 1000 steps is so large, it would be very tedious to move a large texture around at 1 step per mouse click in the slider end caps or even 10 steps per mouse click in the slider bar. The x10 check box helps out here by multiplying the slider movement by a factor of 10. So with x10 not selected the sliders move by 1 or 10 steps per mouse click and with x10 selected they move by 10 or 100 steps per mouse click. This allows for both fast coarse movement and slow fine tuning movement as needed. One more convenience feature is built into the Skew controls. The Skew A and Skew B buttons reset the corresponding group of controls all to 0 when clicked to make it easy to get back to the starting point quickly. The following images show the same frame with all Skew controls reset to the starting point compared to the final result after fine tuning.
