Yes, this way: im = Image.open(‘image.gif’) rgb_im = im.convert(‘RGB’) r, g, b = rgb_im.getpixel((1, 1)) print(r, g, b) (65, 100, 137) The reason you were getting a single value before with pix[1, 1] is because GIF pixels refer to one of the 256 values in the GIF color palette.

OpenCV uses BGR as its default colour order for images, matplotlib uses RGB. When you display an image loaded with OpenCv in matplotlib the channels will be back to front. The easiest way of fixing this is to use OpenCV to explicitly convert it back to RGB, much like you do when creating the greyscale … Read more
This can be done with pure CSS and does not even require media queries. To make the images flexible, simply add max-width:100% and height:auto. Image max-width:100% and height:auto works in IE7, but not in IE8 (yes, another weird IE bug). To fix this, you need to add width:auto\9 for IE8. source: http://webdesignerwall.com/tutorials/responsive-design-with-css3-media-queries CSS: img { … Read more
Answering my own question I spent two days digging through Node.js graphics libraries. node-canvas I tried it first since I’m quite familiar with <canvas> API. It’s a huge plus for a library. it requires Cairo which doesn’t have an easy Windows download. I found it in GTK+ distribution though. moreover it needs native library binding … Read more
The image should be embedded in the message as an attachment like this: –boundary Content-Type: image/png; name=”https://stackoverflow.com/questions/9110091/sig.png” Content-Disposition: inline; filename=”https://stackoverflow.com/questions/9110091/sig.png” Content-Transfer-Encoding: base64 Content-ID: <0123456789> Content-Location: sig.png base64 data –boundary And, the HTML part would reference the image like this: <img src=”https://stackoverflow.com/questions/9110091/cid:0123456789″> In some clients, src=”https://stackoverflow.com/questions/9110091/sig.png” will work too. You’d basically have a multipart/mixed, multipart/alternative, multipart/related … Read more
I think ImageFont module available in PIL should be helpful in solving text font size problem. Just check what font type and size is appropriate for you and use following function to change font values. # font = ImageFont.truetype(<font-file>, <font-size>) # font-file should be present in provided path. font = ImageFont.truetype(“sans-serif.ttf”, 16) So your code … Read more
var img = new Image(); img.onload = function(){ var height = img.height; var width = img.width; // code here to use the dimensions } img.src = url;
scandir: $files = scandir(‘folder/’); foreach($files as $file) { //do your work here } or glob may be even better for your needs: $files = glob(‘folder/*.{jpg,png,gif}’, GLOB_BRACE); foreach($files as $file) { //do your work here }
Sahil has a great answer and I wanted to take that and expand it into an @IBDesignable so developers can add images to their UITextFields on the Storyboard. Swift 4.2 import UIKit @IBDesignable class DesignableUITextField: UITextField { // Provides left padding for images override func leftViewRect(forBounds bounds: CGRect) -> CGRect { var textRect = super.leftViewRect(forBounds: … Read more
It will be approximately 37% larger: Very roughly, the final size of Base64-encoded binary data is equal to 1.37 times the original data size Source: http://en.wikipedia.org/wiki/Base64
