 |
|
How can I change my image object canvas size?
Doing the following will not change it
| Code: |
f = createForm();
object = createImage(f);
object.Width = 100;
processMessages()
print(object.Width,object.Canvas.Width); --> 100 0
object.Width = 200;
object.Canvas.Width = 200;
processMessages()
print(object.Width,object.Canvas.Width); --> 200 100
object.Picture.Bitmap.Canvas.Width = 200;
processMessages()
print(object.Width,object.Picture.Bitmap.Canvas.Width); -->200 100;

you need to write to/access the canvas for it to update.
writing a single pixel to it should usually update it

Well, drawing doesn't update the canvas height/width.

mgr.inz.Player, I'm trying to resize the canvas size, not get canvas size.
For example if my image object width/height are 200/200 and I resize it to 400/400, my image canvas width/height remain 200/200 and do not change to 400/400.
| Code: | f = createForm()
object = createImage(f)
object.Width = 200
object.Height = 200
object.Canvas.getPixel(0,0)
print(object.width,object.height,object.Canvas.Width, object.Canvas.Height) -- 200 200 200 200
object.height = 400;
object.width = 400;
object.Canvas.getPixel(0,0)
print(object.width,object.height,object.Canvas.Width, object.Canvas.Height) -- 400 400 200 200 |

image.Canvas.getPixel(0,0)
print(image.Width,image.Height,image.Canvas.Width, image.Canvas.Height)
image.Width = 200;
image.Height = 201;
image.Picture.Bitmap.Width = 200
image.Picture.Bitmap.Height = 201
