Vector Editor dialog box

Use the Vector Editor dialog box to edit the vector hatches available to draw different rocktypes.

Unless your administrator has enabled Client mode, you can display this dialog box by clicking the Edit Vectors button on the Settings tab of the Options dialog box. If Client mode has been enabled then this dialog box is not available.

Vector pattern: Select the vector pattern to edit.
Add: Add a new schema. You will be prompted for the name to use to identify the schema. This name must be unique amongst the list of schemas.
Rename: Rename the selected vector hatch. The new name for the hatch must be unique amongst the list of vectors. Hatch lists that refer to the vector pattern will now use the new name.
Delete: Delete the selected vector pattern.
Width: Enter the width of the tile used to display the vector hatch in millimetres. This width is used when displaying the vector pattern in isotropic mode - in anisotropic mode the width of the tile is always the full width of the borehole field.
Height: Enter the height of the tile used to display the vector hatch in millimetres.
Background colour: Click on the button to set the background colour for the vector. After changing the colour you need to click Compile and Update to see the results in the preview windows.
Element definitions: The individual primitive drawing operations that describe the vector pattern are entered here in a text form. See below for more information.
Compile and update: Click after making any changes to the element definitions for the vector or a vector patterns. MEGS_Log will attempt to compile the vector element definitions a

The vector pattern itself is defined using a simple series of text commands. Each command specifies a particular drawing primitive, using the syntax below:

A line primitive:
linewidthcolourstyle{coord-pairs}
A hollow (unfilled) rectangle primitive:
rectcolourleft-x-ordinatetop-y-ordinateright-x-ordinatebottom-y-ordinate
A hollow (unfilled) circle primitive:
circlewidthcolourradiusx-ordinatey-ordinate
A filled circle primitive:
fillcirclewidthcolourradiusx-ordinatey-ordinate
A filled polygon primitive:
fillpolycolour{coord-pairs}

In the above:

coord-pairs is a semi-colon separated list of comma separated coordinate pairs.
colour represents the line or fill colour of the primitive as appropriate. This colour can either be specified using a red-green-blue triplet:
(red-component,green-component,blue-component)

where each component is specified by a number between zero and 255, or a hexadecimal representation:

0xRRGGBB

where RR, GG and BB are the hexadecimal representations of the red, green and blue components respectively.
style specifies the linestyle to use when drawing the primitive. It can be one of the following predefined styles: solid, dash, dot, dashdot, or dashdotdot; or a specification of the form:
(style-spec)

where style-spec is a comma separated list of stroke and gap distances.
width specifies the width of the lines in the primitive.
radius specifies the radius of a circular primitive.

All coordinates, distances and widths are specified in units of 0.1 millimetres, with the origin of the coordinate system being at the bottom left of the vector pattern tile.

Changes made to the vector hatches are saved to the users MEGS_Log configuration file when you click the Ok button.
