Image Tool
This tool allows you to insert an image into the Graphics View.
First, specify the location of the image in one of the following two ways:
- Click in the Graphics View to specify the position of the image’s lower left corner.
- Click on a point to specify this point as the lower left corner of the image.
Then, a file-open dialog appears that allows you to select the image file from the files saved on your computer.
Properties of Images
The position of an image may be absolute on screen or relative to the coordinate system. You can specify this on tab Basic of the Properties Dialog of the image.
You may specify up to three corner points of the image on tab Position of the Properties Dialog. This gives you the flexibility to scale, rotate, and even distort images (also see command Corner Command).
- Corner 1: position of the lower left corner of the image
- Corner 2: position of the lower right corner of the image
- Corner 4: position of the upper left corner of the image
- Set point A as the first and point B as the second corner of your image. By dragging points A and B in Move mode you can explore their influence.
- Now, remove point B as the second corner of the image. Set point A as the first and point C as the fourth corner and explore how dragging the points now influences the image.
- Finally, you may set all three corner points and see how dragging the points distorts your image.
- Set Corner 1 to A
- Set Corner 2 to A + (3, 0)
- Set Corner 4 to A + (0, 4)
You may specify an image as a Background Image on tab Basic of the Properties Dialog. A background image lies behind the coordinate axes and cannot be selected with the mouse any more.
The Transparency of an image can be changed in order to see objects or axes that lie behind the image. You can set the transparency of an image by specifying a Filling value between 0 % and 100 % on tab Style of the Properties Dialog.
