crop

is there any lightweight command line batch image cropping tool(Linux or Windows) which can handle a variety of the formats ? Imagemagick is what you want -- tried and true. Ralph In Linux you can use mogrify -crop {Width}x{Height}+{X}+{Y} +repage image.png for CLI image manipulation Imagemagick's convert does the trick for me (and much more than cropping): convert -crop +100+10 in.jpg out.jpg crops 100 pixels off the left border, 10 pixels from the top. convert -crop -100+0 in.jpg out.jpg crops 100 pixels off the right, and so on. The Imagemagick website knows more: http://www.imagemagick.org

I'm trying to create an image for a custom style UIButton using an image from the camera roll on iPhone. The button has a circular background and effectively appears as a circle. Now I need an image to go in the middle of the button that also appears round. How do I cut a square UIImage to appear round with transparency outside of the round area? If masking is involved, do I need to pre-render a mask or can I create one programmatically(ex: a circle)? Thank you! Yes you can use CoreGraphics to draw the mask dynamically. Then you can create the masked image. Example for masking: - (UIImage*)

We are working over a big application with many features and is very difficult change the logic writed I think this is something that you will probably be best off writing yourself as it depends on how your data and models are layed out, whether (and where) you

I am trying to find an app that can detect faces in my pictures, make the detected face centered and crop 720 x 720 pixels of the picture. It is rather very time consuming & meticulous to edit around hundreds of pictures I plan to do that. I have tried doing this using python opencv mentioned here but I think it is outdated. I've also tried using this but it's also giving me an error in my system. Also tried using face detection plugin for GIMP but it is designed for GIMP 2.6 but I am using 2.8 on a regular basis. I also tried doing what was posted at ultrahigh blog but it is very outdated

Good noon, I'm currently trying to understand how i can crop image already loaded on server with 16:9 aspect ratio. For better understandig, if I have 4:3 image i have to cut top and bottom image portions to fit it into 16:9 ratio. Thanks. I took this code example: http://myrusakov.ru/php-crop-image.html and changed the code according to my needs in this way: function crop_image($image) { //$x_o и $y_o - Output image top left angle coordinates on input image //$w_o и h_o - Width and height of output image list($w_i, $h_i, $type) = getimagesize($image); // Return the size and image type (number
