You’ll need to get those bytes into a MemoryStream: Bitmap bmp; using (var ms = new MemoryStream(imageData)) { bmp = new Bitmap(ms); } That uses the Bitmap(Stream stream) constructor overload. UPDATE: keep in mind that according to the documentation, and the source code I’ve been reading through, an ArgumentException will be thrown on these conditions: … Read more
The capitalization is wrong, and you have an extra argument. Do this instead: $(‘img#thumb’).removeAttr(‘id’); For future reference, there aren’t any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined “word” is upper case.
There is a very easy trick. Set padding of that div to a positive number and margin to negative #wrapper { background: url(xxx.jpeg); padding-left: 10px; margin-left: -10px; }
You can use canvas’ context.translate & context.rotate to do rotate your image Here’s a function to draw an image that is rotated by the specified degrees: function drawRotated(degrees){ context.clearRect(0,0,canvas.width,canvas.height); // save the unrotated context of the canvas so we can restore it later // the alternative is to untranslate & unrotate after drawing context.save(); // … Read more
You need to make the following changes: append a tuple (255, 255, 255, 0) and not a list [255, 255, 255, 0] use img.putdata(newData) This is the working code: from PIL import Image img = Image.open(‘img.png’) img = img.convert(“RGBA”) datas = img.getdata() newData = [] for item in datas: if item[0] == 255 and item[1] … Read more
If you want to know the format of an image, you can load the file with the Image class, and check its RawFormat property: using(Image img = Image.FromFile(@”C:\path\to\img.jpg”)) { if (img.RawFormat.Equals(System.Drawing.Imaging.ImageFormat.Jpeg)) { // … } }
Adam Luter gave me the idea for this, but it actually turned out to be really simple: img { width: 75px; height: auto; } IE6 now scales the image fine and this seems to be what all the other browsers use by default. Thanks for both the answers though!
I would vote for sharp: sharp(‘input.jpg’) .resize(200, 200) .toFile(‘ouput.jpg’, function(err) { // output.jpg is a 200 pixels wide and 200 pixels high image // containing a scaled and cropped version of input.jpg }); It’s fast, typically 6x faster than the fastest imagemagick-based node bindings, and runs in very little memory, perhaps 10x less. sharp links … Read more
You have 2 options: Option 1: Remove the width and height attributes and read offsetWidth and offsetHeight Option 2: Create a JavaScript Image object, set the src, and read the width and height (you don’t even have to add it to the page to do this). function getImgSize(imgSrc) { var newImg = new Image(); newImg.onload … Read more
According to Wikipedia, GraphicsMagick is a fork from ImageMagick 5.5.2. As far as I can see, GMagick comes with no new features; the fork is concentrating on better performance and stability, which as @Col says you should test and compare yourself. From a feature perspective, if a library is needed for more than just basic … Read more
