Drawing in WINDEV, WEBDEV and WINDEV Mobile
WINDEV, WEBDEV and WINDEV Mobile include several functions for displaying, drawing, copying and saving the drawings and images from your applications or sites. WINDEV, WEBDEV et WINDEV Mobile propose functions used to: - draw several drawings,
- display any type of image,
- copy the drawings and the images,
- save drawings and images.
Prerequisite depending on the platform Drawing in an Image control To draw in an Image control: - Initialize the drawing in the Image control (dStartDrawing). This initialization is used to allocate a specific memory area for the management of drawings.
- Draw with the drawing functions.
- Insert (if necessary) text into your drawings with dText.
- Perform (if necessary) zooms and copies of images with dCopyBlt.
- If necessary, save the drawing using the save functions (dSaveImageBMP, dSaveImageGIF, dSaveImageJPEG, dSaveImagePNG).
- If necessary, print the file using iPrintImage.
- Destroy (if necessary) the drawing found in memory with dEndDrawing.
 Versions 17 and laterDrawing in an Image variable To draw in an Image variable, some rules must be complied with: - Declare an Image variable.
- Initialize the drawing in the variable (dStartDrawing). This initialization is used to allocate a specific memory area for the management of drawings.
- Draw with the drawing functions.
- Insert (if necessary) text into your drawings with dText.
- If necessary, save the drawing using the save functions (dSaveImageBMP, dSaveImageGIF, dSaveImageJPEG, dSaveImagePNG).
- If necessary, print the file using iPrintImage.
- Destroy (if necessary) the drawing found in memory with dEndDrawing.
 New in version 17Drawing in an Image variable To draw in an Image variable, some rules must be complied with: - Declare an Image variable.
- Initialize the drawing in the variable (dStartDrawing). This initialization is used to allocate a specific memory area for the management of drawings.
