copied!<p>You can use the <code>Clone</code> method to copy an image. Also, writing an image and reading it immediately afterwards is redundant. Try something like the following:</p> <pre><code>my @sizes = ("1280","960","640","480","320","160"); my $src_image = Image::Magick->new; $x = $src_image->Read("/path/to/fullsize/image"); ######################### # Run the requested crop ######################### $x = $src_image->Crop(width=>$input{w},height=>$input{h},x=>$input{x},y=>$input{y}); foreach $size (@sizes) { my $image = $src_image->Clone; $resized = "/path/to/size/folders/$size\/$input{image_ID}\.png"; ############################################### # Size the image down to +2 pixels all around # to handle border opacity when pixel rounding ############################################### $temp_width = $size + 2; $temp_height = ($temp_width * $input{h}) / $input{w}; ########################### # Resize the cropped image ########################### $x = $image->Resize(width=>$temp_width, height=>$temp_height); ######################################## # Calculate final dimensions and coords ######################################## $final_height = ($size * $temp_height) / $temp_width; $final_x = 1; $final_y = 1; ####################################### # Final crop the image for clean edges ####################################### $x = $image->Crop(width=>$size,height=>$final_height,x=>$final_x,y=>$final_y); ######################################## # Write the final cropped image for use ######################################## $x = $image->Write("$resized"); } </code></pre>
