In Delphi 7, I have a library that uses the TCanvas component to output some information. The resulting image is about 4800*6000 pixels and I would like to print it and save it as .jpeg. To achieve this, I created a TBitmap and gave its Canvas as parameter to the library and then I assigned the bitmap to the jpeg. Apparently, this is ta...

I am aware that Java includes very advanced image processing API's but what I'm looking for is a pure Java API (uses Java2D) that is "phrased" in terms more appropriate to common tasks of web image processing i.e. I want to write: image.scale(0.2) instead of AffineTransform t = new AffineTransform(...) t.resize(...) t.translate(...) ...
Hi all, I've used GD before, but only ever for resizing/generating images on the fly - though I'm pretty positive it has the capabilities to do what I'm after. As simply as possible, I need to check an image to find out whether it has a light background or a dark background. I.e. if the background is predominately 'light' I'm returned ...
I want to do some image processing with OpenCV (in Python), but I have to start with a PIL Image object, so I can't use the cvLoadImage() call, since that takes a filename. This recipe (adapted from http://opencv.willowgarage.com/wiki/PythonInterface) does not work because cvSetData complains argument 2 of type 'void *' . Any ideas? ...
Hi, I want to have a dynamically generated Neon sign on my site. I want to pass it some text, have it rendered as an image (in a neon sign - something like: http://www.pixelhivedesign.com/tutorials/Neon+Sign+on+a+Textured+Surface/ ) and then show the image to the user. I dont think CSS font tricks can do this - that would have been fa...

This isn't really OCR, since it's not recognizing characters, but it's the same idea. Anyone know of an image-processing library or established algorithm for retrieving the values from a (raster) plot image? For instance, in this graph, it's hard for me to read exact values with my eyes because there's such gaps between gridlines: I...
I'm trying to "resave" an image and am getting the error "A generic error occurred in GDI+". I've done some searching around this error, however haven't found a solution yet!

Hi there, Long ago I created a small library for resizing images using imagemagick through system(...) because I did not feel that the build-in imagemagick functions for PHP were sufficient. However, recently I had to port this to a symfony project and I chose to use sfThumbnailPlugin (if I remember correctly). This unfortunately didn'...
