#ASPECT RATIO RESIZE CALCULATOR HOW TO#

The end result is that a lot of variables that were using are now gone e.g. I've written a console app that tries to illustrate how you could simplify your code a bit. If (newWidth > BOXWIDTH || newHeight > BOXWIDTH) if one of the two dimensions exceed the box dimensions calculate new dimensions based on aspect ratio

Private static ImageDimensions CalculateNewDimensionsForImage(Bitmap original)įloat aspect = original.Width / (float)original.Height Private static bool ImageIsBox(Bitmap original) Using (FileStream fs = new FileStream(imagePath, FileMode.Open)) Private static Bitmap LoadOriginalImage(string imagePath) Return new Bitmap(original, newDimensions.Width, newDimensions.Height) Var newDimensions = CalculateNewDimensionsForImage(original) Return new Bitmap(original, BOXWIDTH, BOXWIDTH) Here's how you can refactor your code a bit: namespace ConsoleApplication1īitmap original = LoadOriginalImage(imageLabel.Text) Working out Resizing Using the Resize Calculator Now that you know your cropping values, you can resize. ResizedImage = new Bitmap(original, newWidth, newHeight) Make sure to correct all of these before you hit Apply.

How to Calculate Aspect Ratio The aspect ratio calculator is simple to use.

This signifies the image's width is double its height.

depending on which of the two exceeds the box dimensions set it as the box dimension and calculate the other one based on the aspect ratio Calculate Reset What is the Aspect Ratio An image's aspect ratio is the proportional connection between its width and height. In the current example rectHeight rectWidth || newHeight > rectHeight) if the image is squared set it's height and width to the smallest of the desired dimensions (our box). Using (FileStream fs = new System.IO.FileStream(imageLabel.Text, System.IO.FileMode.Open)) Is there a more efficient way to do this? Is there something wrong with my code (from the results it looks ok)? Is there a 'shorter' version to do this? Bitmap original, resizedImage The Aspect Ratio calculator, among other purposes, can be used to resize a photo while retaining the original aspect ratio ie the original width to height. I think that some parts of the code are not needed (for example if it's a box image). I wrote some code that resizes an image to fit in a given box.
