Manipulating Image Editor controls programmatically
WINDEV allows you to programmatically manipulate Image Editor controls. To do so, use the control variable in the code. Image Editor controls can also be manipulated programmatically via Picxxx functions. These functions are used to create, save, open and close an image in an Image Editor control. This help page explains how to programmatically manipulate Image Editor controls. Displaying an image in an Image Editor control To display an image in an Image Editor control, you can: - assign the image file directly, or assign the image file path to a variable.
EI_MonImage = "C:\Temp\MonImage.gif"
CheminImage = fCurrentDir() + "\MonImage.gif"
EI_MonImage = CheminImage
- assign a variable of type Image.
MonImage is Image
MonImage = dLoadImage("image.png")
EI_MonImage = MonImage
