Re: Best sharpen settings for multiple image sizes

Yes. I edited the above post to correct that. I tried -sharpen and -unsharp, but neither of them worked as well as -adaptive-sharpen. -unsharp definitely has some potential, but it seems to work a little too well for what I'm doing. The images output are sharp to the point of looking jagged in certa...

Re: Best sharpen settings for multiple image sizes

I am getting slightly better results with "-adaptive-sharpen", "0x0.6'. Higher sigmas (2, 4 even 6) didn't help at all. Processing speed is absolutely key for what I am doing, so I thought that the color conversion might be faster on the smaller resized image. I don't know if it really makes any dif...

Re: Best sharpen settings for multiple image sizes

I tried this with "-adaptive-sharpen", "0x0.5" and "0x0.2" but it's just not turning out decent quality for the smaller sizes (135x135 is especially bad...Smaller than that and it's too small to be noticeable anyway).

Best sharpen settings for multiple image sizes

I am running an automated process via a VB script and the IMage Magick COM+ library that processes thousands of images a day for web based viewing. The program takes a source image and resizes it from the initial size (Usually 600x600 or larger) into various smaller sizes (The exact sizes depend on ...

Re: Optimizing Image Sizes

Thanks for the input. By replacing -resize with -thumbnail and -sharpen, "0" with -adaptive-sharpen, "0" I was able to bring the size down by almost 50% while maintaining quality. I am now getting smaller image sizes than Photoshop puts out, with equivalent or better quality. I realize now that I po...

Optimizing Image Sizes

I am developing a script using the ImageMagick COM+ component to process images in a production web environment. We currently use a legacy process that utilizes the Photoshop COM + interface, so this new script will be replacing that process. By way of disclaimer, I am not a graphics expert, so I ap...
