cIntBMP - a library for creation of BMP images - libreria per MetaTrader 5

This class is designed for creation of bmp images.

Examples:

An example of DrawTriangle() method

An example of DrawRectangle() method

An example of DrawCircle() method

An example of Fill() method

Usage:

The cIntBMP.mqh file should be located in MQL5/Include folder. The demo of cIntBMP class usage is located in the eBMP.mq5 file. Copy this file to the MQL5/Experts folder, open it in MetaEditor, compile and attach to the chart.

Using cIntBMP class:

1. Include file with class:

#include <cIntBMP.mqh>

2. Delcare the cIntBMP class variable, for example "bmp":

cIntBMP bmp;

3. Set image size and background color (using Create(...) method, see below).

4. Draw on the image.

5. Save (using the Save(...) method).

6. Show (using the Show(...) method);

When finished:

1. Delete graphic object (using the Hide(...) method).

2. Delete the file (using the Delete(...) method).

Class Methods:

• Create(int aSizeX, int aSizeY, int aBGColor) - Sets image size and background color.
  aSizeX - width (in pixels);
  aSizeY - height (in pixels);
  aBGColor - background color;

• SetDrawWidth(int aWidth) - Sets pen width.
  aWidth - pen width.

• DrawDot(int aX, int aY, int aColor) - Draws a dot.
  aX - X coordinate;
  aY - Y cooordinate;
  aColor - color;

• DrawLine(int aX1,int aY1, int aX2, int aY2, int aColor) - Draws a line.
  aX1, aY1 - starting coordinates;
  aX2, aY2 - ending coordinates;
  aColor - color;

• DrawRectangle(int aX1, int aY1, int aX2, int aY2, int aColor, bool aSolid=false) - Draws a rectangle.
  aX1, aY1 - coordinates of the upper left corner;
  aX2, aY2 - coordinates of the lower right corner;
  aColor - color;
  aSolid - true - filled.

• DrawTriangle(int aX1, int aY1, int aX2, int aY2, int aX3, int aY3, int aColor, bool aSolid=false) - Draws a triangle.
  aX1, aY1, aX2, aY2, aX3, aY3 - edge coordinates;
  aColor - color;
  aSolid - true - filled.

• DrawCircle(int aX, int aY, int aRadius1, int aRadius2, int aColor, double aRatio=1.0, double aAngleFrom=0.0, double aAngleTo, bool aSolid=false) - Draws a circle.
  aX - X coordinate;
  aY - Y coordinate;
  aRadius1 - radius of the 1st circle;
  aRadius2 - radius of the 2nd circle;
  aColor - color;
  aRatio - ratio (ratio=1, circle, overwise ellipse).
  aAngleFrom - starting angle;
  aAngleTo - ending angle. if aAngleFrom=aAngleTo, it will draw a circle;
  aSolid - true - filled circle/ellipse.

• Fill(int aX, int aY, int aColor) - Fills the area.
  aX, aY - coordinates of the fill area;
  aColor - fill color.

• TypeText(int aX, int aY, int aColor) - Prints text on the image.
  aX, aY - coordinates of the left upper corner of the text;
  aColor - text color.

• Save(string aFileName, bool aToImages=true) - saves the created image to file.
  aFileName - File name (it isn't necessary to specify the extension) ;
  aToImages - file will be saved to the MQL5\Images\ folder, overwise it will be saved to the MQL5\Files\ folder.

• Show(int aX, int aY, string aBMPFileName, string aObjectName) - Shows the image on the chart.
  aX, aY - coodinates;
  aBMPFileName - file name of the image;
  aObjectName - graphic object of OBJ_BITMAP_LABEL type.

• Hide(string aObjectName) - Deletes graphic object with the specified name.
  aObjectName - name of the object to delete.

• Delete(string aFileName, bool aFromImages=true) - Deletes a file.
  aFileName - Name of the bmp file to delete (without path, it isn't necessary to specify the extension);
  aFromImages - if true, the file will be deleted from MQL5\Images\ folder, overwise it will be deleted from MQL5\Files\ folder.
