How to draw?

Drawing in an Image control

To draw in an Image control:
  1. Initialize the drawing in the Image control (dStartDrawing). This initialization is used to allocate a specific memory area for the management of drawings.
  2. Draw with the drawing functions.
  3. Insert (if necessary) text into your drawings with dText.
  4. Perform (if necessary) zooms and copies of images with dCopyBlt.
  5. If necessary, save the drawing using the save functions (dSaveImageBMP, dSaveImageGIF, dSaveImageJPEG, dSaveImagePNG).
  6. If necessary, print the file using iPrintImage.
  7. Destroy (if necessary) the drawing found in memory with dEndDrawing.
Versions 17 and later

Drawing in an Image variable

To draw in an Image variable, some rules must be complied with:
  1. Declare an Image variable.
  2. Initialize the drawing in the variable (dStartDrawing). This initialization is used to allocate a specific memory area for the management of drawings.
  3. Draw with the drawing functions.
  4. Insert (if necessary) text into your drawings with dText.
  5. If necessary, save the drawing using the save functions (dSaveImageBMP, dSaveImageGIF, dSaveImageJPEG, dSaveImagePNG).
  6. If necessary, print the file using iPrintImage.
  7. Destroy (if necessary) the drawing found in memory with dEndDrawing.
