In the dialog you have a choice for a round or square eraser shape, whether the tool should erase (N) or paint with white.
You can set the brush size by typing the size in pixels, by using the stepper, or by moving the mouse over the sample image and using two-finger gesture scrolling up and down, or with the scroll wheel of the mouse.
You may use the Mouse Shaker to switch between the round and square brush. This mouse shaker feature is global for all of WildTools, thus you can set it on or off from many places, but there is only one global setting.
This tool uses Apple's Core Image for smaller images and Quartz for larger images. Core Image uses all the computing power of the computer including all of the CPUs and GPUs on board. It is the first use of parallel processing in PowerCADD, and it is unbelievably fast. However it also has a size limit, and we are uncertain where those limits are exactly. As a temporary measure, you can change the maximum Core Image Pixel size in this dialog.
To use the tool:
Move the cursor over a bitmap in the drawing.
The bitmap will hilite with either your normal hilite color (shown in green above) if Core Image is going to be used, or yellow if Quartz is going to be used. The hilite rectangle will extend beyond the image by the size of the Eraser tool brush, so you may erase along the edge of a bitmap.
To change the size of the brush, press the Option key and drag the on-screen slider up and down.
Click and drag on the bitmap to erase or paint to white. When you have erased a portion of the image, you can see through the image to the hilite color.
