I want to know how to find the length and width of the image that has been re-sized to fit in the picturebox zoom mode
I tried this code but I got the original image size which I don't want.
PictureBox2.Width
PictureBox2.Height

I am trying to draw a bounding box around the monkey's face in this image. The coordinates I want to use are the following:
64,111
347,111,
64,304,
347,304
I am displaying the image with resizeMode = contain which results in the bounding box being misplaced and the wrong size.
I think the top-left of the rectangle should be at 64,111 using position absolute and the width and height should just be the difference between the points (width = 283 and height = 193). I know that since the image is not being displayed at its full height and width I need to scale down the bounding box accordingly. However, I can't figure out what the image's final size is after it has been resized. How can I figure this out in order to display my bounding box correctly?
Here is my code so far: https://snack.expo.dev/#melampus123/forlorn-raisins
I have a problem centering my image on the RDLC report. I'm using image control and external source (path) for the image but I don't know the size of the image and I want to keep the actual size of the image but centered in image control. Is there any option that I can read image width in expression for left padding?
My idea is to read image size and I know image control size, so I can set left padding as (control size - image size) / 2.
Any other idea is welcome.
As A Begineer I've made a Puzzle game and it's working fine in Iphone Simulators.
But problem occurred when I run it in bigger Screen like IPad Air 2.All the picture aren't fitting perfectly in the buttons
(Note that Images are applied on buttons not in the Background of
buttons)
As image size not fit to given size of button, may be due to size concern of aspect fit property of imageview of button. You can try to scale image proportionally to size of imageview of button and get desire result.
You can refer to this link for scale image as proportionally to desired size.
scale Image in an UIButton to AspectFit?
i have some picture which is 675x503. I would like to make more width on it and let's say to 1024 and in height to 400. How to do that without cutting my image and keep quality? I just would like to have this image on my website top. I got photoshop 6. I tried with Image->image size but its not what i need.
If you don't want to cut the picture at all, this will distort the image due to different height and width ratios. If this is not an issue, you could simply hit ctrl(or cmd)+t when the layer with the picture is selected. It will let you resize and rotate the entire image. There is also an option in the Image -> Image Size menu called "Bicubic Sharper", found in the drop-down list at the bottom of the menu(Photoshop CS6). It's meant for image reduction and should also solve your problem.
I`m try get screen capture from retina display, and draw this image on window.
I can get capture
CGDirectDisplayID displayId = CGMainDisplayID()
CGImage imageRef = CGDisplayCreateImage(displayId)
image have a size 2560x1600
Now, i need draw this image on window. But if, i resize window to full screen, window return size 1280x800. If i wont draw image on window, i need scale image to 1280x800. Image lost quality, this is not good.
Please help me, how i can get screen capture from retina display and draw his on window, without lost quality ?
You can find out actual window size in pixels by passing its frame to this method:
-[NSWindow convertRectToBacking:]
Just draw the image to the view's bounds. In theory this is a scaling operation, but in reality it's not because the view's bounds are in points, not pixels. The backing buffer for the view is at the same DPI as the original screen capture, so it will be a straight blit. No detail will be lost.
