Small update, when going back to v2.54 the .sharpen command works okay. I guess I didn't switch back when I thought I did.

I have many 45 mpixel images that I process for presentation on the web They all behave this way. Here is an example: http://herbarium.uvsc.edu/virtual/viewer.asp?file=03390s1.jpg (only the main image gets sharpened, and currently sharpening is disabled). There is a link for downloading the raw imag...

Gflax 2.66 problem

I installed v2.66 on my server, and found that activating the filters (like gflax.sharpen and .enhancedetails) crash the .dll during execution. All I get is the ASP 0115 error, something about a trappable error in external application; script cannot continue. When I tried going back to v2.54 the beh...

Well, my servere will choke. Take a look at the paqe I posted and see if you want to pre-make and cache all the versions that might be called for. We push imaging to different processes right now anticipating the move to different servers. And take another look at the page I posted and say when we m...

Well, I hope by now you've figured out why no one has yet responded. Putting images in a database is a might poor way of doing things, and if you haven't paid attention to the advice I know you've read already, why would we think you'll listen to what we have to say. Anyway, here's a nice bit of ann...

Just a late observation: ALL resizing to a smaller image results in blurred-looking images. Only applications that sharpen after every resize (and only the most dumbed-down versions would do that automatically) result in a good loking thumbnail. If you make a thumbnail, sharpen gently afterwards. In...

Installs easily, just register the .dll. Doesn't use many server resources, even with big processing jobs.

BGR instead of RGB?

I just noticed, while working on specific colors in an image, that the OLE-COLOR format is BGR, not RGB!

Test this with GetColorAt if you want to confirm it.

Is this because of GFLAx, WIndows, or my particular setup?

Is it possible to map the remote directory as a drive on your server? That way you will have a physical path on the IIS server to the image directory on the image server.

Transparent colors for drawing?

Is it possible to specify an RGBA color in GFLAx?

I have a colored map I want to draw transparent circles on to indicate populations, so I can see the town name under the circle.

GFLAx JPEG2000 Request

I've been woking on a website that uses many large images, and displays parts of them (for example, see http://herbarium.uvsc.edu/virtual/viewer.asp?file=08218s1.jpg - click on the big image to zoom in) There is a problem. It takes a couple seconds to open and decompress these images before I can st...

Run GflAx on a 64 bit processor?

Anyone here run GflAx on a 64-bit processor, specifically the Intel Itanium 2 or 64-bit XEON (with EM64T)?

Is image processing much faster? We're using 35MPixel color images, and need all the speed we can get.

Aha! I got it to work. I needed to move all transparency information to a point after I reduced the number of colors. Here's the end of the code: GflAx.ChangeColorDepth(1) GflAx.EnableLZW = TRUE 'needed to write a .gif GflAx.SaveFormat = 2 '1=jpeg, 2=gif, 3=png if bTransparent then GflAx.UseTranspar...

I'm not sure I understand your question. You are trying to open a file on the client computer directly from the server-side script? You need to use a different mechanism of moving the file to the server first, then open it there. No script can open a file on the client's computer; that would be a ma...
