Then we calculate the new width and height to scale the image to. To resize an image using PIL and maintain its aspect ratio with Python, we can open the image with Image.open. And finally, we call image.save with the file path to save to to save the resized image.
#Image resize aspect ratio code#
I've written a console app that tries to illustrate how you could simplify your code a bit. We use Image.ANTIALIAS to apply image anti-aliasing while resizing. 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 Now you can select the image that you want to resize in the PDF.

After opening the PDF file, you will need to enable the 'Edit' option. Then click on the 'Open File' button and select the target PDF file from your local folder. Private static bool ImageIsBox(Bitmap original) After installation, launch PDFelement on your computer. 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) Prevent an image from appearing stretched by locking the aspect ratio when changing the width or height. Before changing the dimensions, notice the lock symbol to the left of height and width. Here's how you can refactor your code a bit: namespace ConsoleApplication1īitmap original = LoadOriginalImage(imageLabel.Text) Open your screenshot or image in the Snagit Editor, select Image from the top menu, then Resize Image. ResizedImage = new Bitmap(original, newWidth, newHeight) 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 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 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.
