GDIPLUS: can i draw an image using corners?

[Cambalinho]

the Gdiplus::Graphics::DrawImage() have a way for draw using coners? or the rotation points?

[coder777]

What does 'coners' or 'rotation points' mean regarding an image?

[Cambalinho]

i mean 'upperleft' coner, 'upperright' coner, and the others.
i think 'coner' is the right word.

Think again. Corner, or.....

[in] x
Type: INT
Integer that specifies the x-coordinate of the upper-left corner of the destination position at which to draw the image.

[in] y

x and y coordinates.

Maybe you mean rounded corners ?

There are quite a few overloads of DrawImage that allow passed REALs or a passed Point/PointF or Rect/RectF to supply the coordinates of the upperleft corner of the image to draw. And/or to specify the location and size of the area to draw the image.

Maybe you mean rounded corners ?

Rounding off the corners of an image would probably require applying a mask of the rounded corners to the image and then transforming the masking area to be transparent when drawing the image.

OR

Draw a rectangle with rounded corners, filling the area with an image.

Doable, for sure.

Amazing what doing a bit of searching the bowels of the interwebs can scrape up.

sorry... not rounded... just normal corners.
but adding the 4 points, instead just X,Y and Width, Height.
