I've often wondered, if I load a compressed image file, edit it and the save it again, will it loose some quality? What if I use the same quality grade when saving, will the algorithms somehow detect that the file has already be compressed as a JPEG and therefore there is no point trying to compress the displayed representation again? W...
I have a sequence of jpg images that I am capturing and rendering to the screen to create a video. I am decompressing the image from a MemoryStream using a JpegBitmapDecoder and rendering it by setting the Source on an Image control. This seems to work okay, but the processor overhead is pretty high. The images are 1280x720, running...

Hi, I'm using the Ghostscript API from c#, to convert multipage PDF's to jpgs. My issue is with colour conversion. When I open the Source PDF in photoshop, and export to jpeg, each colour in each jpeg matches the colours of the original PDF perfectly.

I'm trying to open a file to bytes, convert it to a string, modify some data (think Steganography) and convert the file back to bytes and save it as a jpeg. So far, everything I've tried has corrupted the file in converting it to a string. I've tried converting it to a 64-bit string, but of course that's a bit hard to modify the data in ...

Now, the image sizes that users want to see have changed. Since there are many images that won't need to be resized, we have built a service...

I first looked into doing this with GDI+ but it gives me errors telling me min/max haven't been defined (defining them just brings more problems), I then looked into libpng's C++ bindings (png++) and couldn't get the examples to compile. thanks, Mikey ...
Hello, I'm using Apache's mod_rewrite to route requests for .jpg files to a directory outside my web root. It generally has been fine, but there are a few images that do not display. I then realized that when I use PHP's get_headers() function on my image URLs, they are all returning "Content-Type: text/html; charset=UTF-8" instead ...

Hello, I'm using PHP to copy JPGs from a remote server to my own server. Is it best to simply use the copy() function, or are the jpeg-specific functions better? For example: $copy = copy($remote_url, $dest_file); -OR- $img = imagecreatefromjpeg($remote_url); $copy = imagejpeg($img, $dest_file); imagedestroy($img); What would th...
