Showimg img width & height

How do I show an image with showimg with the specified image width and height?

Is there a way to do this?

You can use stretchx and stretchy to stretch the image.

To work out the size of the stretched image its easy:

image width * stretchx = displayed image width.

The other way around is fairly simple. Just:

stretchx = desired width / actual width

You can't do it with showimg but you should be able to with drawimagestretched.

in gs2 it's getimgwidth("name.png"); and you can't set the width with it.

as i said you can just use

PHP Code:


		
			
with(showimg(200,"image.png",x,y)) {
stretchx = 300/getimgwidth("image.png");
}

Will make the image 300px wide on screen.

n.b. the only issue with this is that X and Y of the showimg will not be in the top left corner of the image any more.

Yes you currently need to use stretchx and stretchy to change the size. To correct the position of the image you need to do then:

PHP Code:


		
			
x += (1-zoom*stretchx)/2*getimgwidth(image);
y += (1-zoom*stretchy)/2*getimgheight(image);

Another way is to use a polygon with an image:

PHP Code:


		
			
polygon = {x,y, x+mywidth,y, x+mywidth,y+myheight, x,y+myheight};
image = "yourimage.png";

Replace mywidth and myheight with the preferred size. This will only work if you display a full image (not using partx etc.)

The simpliest way would be to use a GuiBitmapCtrl, I am not sure where you want to display it though.

Couldn't you just do new TDrawingPanel? :)

Details, Details Zokemon. I'll try various things and we'll see what works best.
