Format of TriQuick TVL files

 Overlay=..\..\templates\shared.tvl

 Use object of "Image" type to place vector or raster image on the diagram background. Its record consists of one line with file name (with optional path) after the equality sign. Image size will be adjusted according to ranges of axes specified in the file header. However, if image is a Windows metafile with saved coordinates then ranges of axes will be reset (i.e. diagram borders stored in metafiles override TVL header values).
 The character "B" or "F" must follow the equality sign for all objects except of "Overlay" and "Image" types. "B" means that this object should appear on the diagram background, i.e. behind data points, grid and axes. "F" means that the object should be placed on foreground and overlap data points, grid and axes. This character may be followed by visibility flag separated by space ("Y" – object is visible, "N" – object is hidden). Objects are visible by default (if visibility flags are omited). Name of the object appear at the end of the first line after the semicolon (;). Example of the first line:

 Polygon=B Y;Small yellow triangle

 The second line contains most common parameters of the object separated by spaces. These parameters may be different a little depending on the object type.

Polygon
 The second line:

• LineColor – outline color
  
• LineWidth – outline width (in screen pixels), integer from 1 to 9
  
• LineStyle – outline style, integer from 0 to 5:
  0. solid line
     
  1. dashed line
     
  2. dotted line
     
  3. dash-dot line
     
  4. dash-dot-dot line
     
  5. no outline
     
  However, outline is always solid if its width is more than 1 pixel.
  
• FillColor – fill color
  
• FillStyle – fill style, integer from 0 to 7:
  0. solid fill
     
  1. no fill

  5. diagonal hatching to the left bottom corner (backward)
     
  6. upright cross hatching
     
  7. diagonal cross hatching
     

 The third line contains one integer: number of poygon vertices, and the other lines contain their coordinates (one line per vertex).
 Example of the rectangle description:

 The second line:

• LineColor – line color
  
• LineWidth – line width (in screen pixels), integer from 1 to 9
  
• LineStyle – line style (hereinafter refer to the same parameters for polygons)
  

 The third line contains one integer: number of line nodes, and the other lines contain their coordinates (one line per node).
 Example of the polyline description (for ternary diagram):

• FillStyle – fill style, for closed curves only
  

 The last two parameters are omited in the case of opened Bezier curve.
 The third line contains one integer: total number of curve nodes and control points, and the other lines contain their coordinates (one line per node or control point). Node coordinates are preceded by characters specifying their types (separated from coordinates by spaces):

• C – cusp (vertex) node: the point of line break;
  
• S – smooth node: line maintains the smoothness but has different curvatures on either side of the node (i.e the control points lie on the tangent line but at different distances from the node);
  
• E – equidistant (symmetrical) node: a smooth line with the same curvature on both sides of the node (i.e. the control points lie on the tangent line and at equal distances from the node).
  

 If type of node is not specified then it is regarded as a cusp node.
 First and last nodes of opened Bezier curves can only be of the cusp type. Coordinates of the first and last nodes of closed curves must be identical.
 Example of opened single-segment Bezier curve (with two end nodes and two control points between them):

Bezier=B Y;4FeAct+3An=11Hed+3Alm+7Qtz+4H2O

40.759 57.979

Text
 The second line:

• Font – font name (registered in the operating system) followed by semicolon (;)
  
• Charset – code page number (charset). For example, code pages for standard fonts in localized RU-version of Windows XP are:
  0. Default code page (selected in OS)
     
  1. Russian
     
  2. ANSI
     
  3. Hebrew
     
  4. Arabic
     
  5. Greek
     
  6. Turkish
     
  7. Latin (Baltic languages)
     
  8. Latin (Eastern and Central European languages)
     
  9. Vietnamese
     
  However, available charsets and their number depend on concrete font implementation. It's a good idea to use default charset (0) in most cases.
• Color – text color
  
• Size – character size (in points), integer
  
• Bold – "Y" – yes, "N" – no
  
• Italic – "Y" – yes, "N" – no
  
• Underline – "Y" – yes, "N" – no
  
• StrikeOut – "Y" – yes, "N" – no
  
• Background – draw background: "Y" – yes, "N" – no (by default, i.e. this field can be omited)
  

 The third line contains one rational number: slope of the text (dY/dX, negative values allowed).
 The fourth line contains one integer: number of text strings (n).
 Then n lines with text strings.
 The last line contains coordinates of the text block center.
 Example of text block:

Text=F N;Label on phase transition line
Arial; 0 #800000 12 Y N N N
0.028
2
Diamond
Graphite
856 39.3

Info
 The second line is the same as for the "Text" type objects (see above).
 The third line contains two-character code (case insensitive) which define position of the text block relative to diagram axes. Allowed characters:

• L – at the left end of horizontal axis
  
• R – at the right end of horizontal axis
  
• T – at the top end of vertical axis
  
• B – at the bottom end of vertical axis
  
• C – at the center of horizontal or vertical axis
  

 Order of characters in the code (i.e. order of axes) is not important. However, TriQuick writes horizontal axis at first.
 The fourth line contains one integer: number of text strings (n).
 The last lines of "Info" block are n text strings.
 Example of information text block:

Info=F;Information
Arial; 0 #800000 12 Y N N N Y

Comments in TVL-files
 Comment strings can be placed between blocks with descriptions of objects without any special comment markers. Comment can also appear at the end of any string after preceding pipe character (|). However, TriQuick ignores comments while reading TVL-files and never writes them at saving..

Color values in TriQuick files
 Colors in TriQuick text files are represented by 8-bit RGB values written as standard hexadecimal integers (using digits 0..9 and A..F). Color value starts from the suffix (#), followed by 3 hexadecimal 2-digit numbers written together with the next order of channels: R, G, B. For example, "#FF00BB" defines bright pink color with maximum value of the red component R (FF=255), minimum value of the green component G (00) and intermediate value of the blue component B (BB=187).

Coordinate records in TVL-files
 All coordinate values are written as floating point or integer numbers. TriQuick allows different formats, including exponential (e.g. "1.25e-3"). Number of digits after the decimal point may also be different depending on value of the Precision parameter.
 The only version of coordinate record for rectangular diagram is a two numbers separated by one of delimiter symbols specified by Delimiters variable of the initialization file TriQuick.ini (default symbol is tabulation with ASCII-code 9), first for the horizontal axis (X), then for the vertical axis (Y).
 Ternary diagrams allow two equivalent coordinate systems and, therefore, two versions of coordinate record are possible. You can use general rectangular coordinates anywhere in the diagram field, inside and outside the triangle of axes. Vertices of this triangle correspond to the next general rectangular coordinates: the top vertex T (X=0.5, Y=√3/2), the bottom left vertex L (X=0, Y=0) and the bottom right vertex R (X=1, Y=0). Ternary coordinates allowed only inside the triangle. These are triples of positive values written with the order T, L, R. TriQuick uses ternary coordinates by default. The program always normalizes entered ternary coordinates to 100% (i.e. T+L+R=100). For example, these two records correspond to the same point on the ternary diagram: (T=50, L=30, R=20) and (X=45, Y=43.301..).
