An example of an image I'd like to do the fill operation on can be found here: https://www.dropbox.com/s/9w1wbnvvqdk5gr1/FillHoleImage.psd?dl=0 The result I want is that every black pixel in the image is replaced with a pixel taken from the closest point in the image that has a non-black colour. In ...

Thanks, I hadn't been certain that IM would preserve the bit depth on save. I should have provided more detail. I am reading a 16 bit per pixel loss-less PSD and after processing (if any) I need to save it as as 16 bits per pixel loss-less TIFF or PNG. I am using the Q16 version of ImageMagick 7 - I...

When saving the results of an image magic operation to a tiff or png, is there a way to specify 16 bit int per channel output?

Thanks

I have an area of an image which is empty (black or transparent). I would like to fill the area with the colour from the nearest point on the boundary. Effectively spreading the colours out from the border.

Is there a way to do this with image magic?


Thanks

Good advice, I've learnt my lesson. I'm testing code my game renderer and hadn't expected this to be visible. Valuable lesson though as I now know my renderer is sensitive to this kind of compression artefact.

Thanks

Thank-you for coming back so quickly. I just loaded TestOut.jpg into Paint.Net and then zoomed in on the area around 1240,256 and then took a screen shot, so you can see the individual pixels blown up. Here's the picture added to dropbox. https://www.dropbox.com/s/6zbqb5aw4r8ecs6/TestZoomedIn.png No...

Thank-you for your help

I have a script (see below) that uses -distort SRT to rearrange and slightly scale two rectangles and then merge the two new rectangles back into one. If I save out the cut out rectangles they appear exactly as I would expect. However, when I merge them together into one image, there is a slight col...

I've fixed this by replacing -repage with -set page and the same arguments. Can anyone tell me what the difference in meaning between -repage and -set page is? It's clear that snibgo's statement that -repage can't accept expressions is correct. Is that the expected behaviour? I didn't see anything i...

It's possible Pano2VR will do what you want.

I'm using the Windows Commandline version of Convert and I have a batch file that contains the following command: convert^ -virtual-pixel horizontal-tile-edge^ -verbose^ %1^ ^( -clone 0^ -set option:distort:viewport "%%[fx:w/2]x%%[fx:h]+0+0"^ -distort affine "0,0,0.5,0.5,%%[fx:w/2],%%...
