Attempting to write a definition of DPI has lead me to: DPI (dots), PPI (points), LPI (lines) all refer to the same concept hereafter referred to as DPI. DPI is a device dependent measurement. It says, "This is the resolution of this device." Vector based files are not tied to any one DPI (they expand and contract to conform to a cer...

Step 3) Profit! (i.e., application opens raster image, vector file describing masks, does interesting stuff to areas of interest based on runtime ...
In a .NET CF application I wrote, one of the features is to acquire frames from remote cameras. Frames are acquired as single jpeg images and displayed on the screen when available. It was a good enough solution, but I don't like the fact that the time needed to convert the stream into an Image object, with the Bitmap() constructor, is ...

I want to to create a jsp that serves a downsampled image with decent quality (not pixelated) as per the passed image width/height (e.g. getimage.jsp?imageid=xxxx&maxside=200) .

Hi, the title sums it up really. Using the standalone exiftool program to dump all image metadata to a console I can see a line Color Space Data : RGB It looks like this is taken from the ICC-header I want to get the same data programatically in java.

I'm looking for a web based upload manager, with good support for images. It should be as easy as possible for novice users to "add images to a website". I could use such a thing for two use cases: A CMS for external use, needs proper image support (1-file upload doesn't quite cut it). A Wiki for internal use, to get popular it will ne...
Can you recommend an open source library (C or C++) to convert MS Office files into a set of images? I am evaluating ImageMagick and while it does support PDF files, it does not work with MS Office files. ...
I want to, from JavaScript, access as a variable the file that is loaded as an image in an img tag. I don't want to access its name, but the actual data. The reason for this is that I want to be able to copy it to and from variables so that I can , among other things, change the image without reloading it. Can this be done? If so, ho...

What is the best way to scale a 2D image array? For instance, suppose I have an image of 1024 x 2048 bytes, with each byte being a pixel. Each pixel is a grayscale level from 0 to 255. I would like to be able to scale this image by an arbitrary factor and get a new image. So, if I scale the image by a factor of 0.68, I should get a new i...
I have a JPanel to which I'd like to add JPEG and PNG images that I generate on the fly. All the examples I've seen so far in the Swing Tutorials, specially in the Swing examples use ImageIcons. I'm generating these images as byte arrays, and they are usually larger than the common icon they use in the examples, at 640x480. Is there ...

I have a webapp from which I'd like to insert diagrams and images quickly and easily. I expect there is, somewhere out there, a webservice which will take a URL with a parameter that describes the vector graphics or diagram and returns an image. No unlike what google charts does for graphing data. Any resources or ideas on this? If I...
I want to let the user draw on an image in a browser. In other words, I need both bitmapped graphics and drawing capabilities, whether vector or bitmapped. Canvas looks good, but is not supported by IE, and though there is ExCanvas, I wonder if ExCanvas is stable enough for consistent use in IE6 through 8. Or best of all, is there an o...
On PHP, they have a way to restrict file size AFTER uploading, but not BEFORE uploading. I use the Malsup jQuery Form Plugin for my form posting, and it supports image file posting. I was wondering if perhaps there's a restriction where I can set how many bytes can pass through that AJAX stream up to the server? That could permit me to ...
