identifying a conversion problem
Posted: 2010-09-29T00:05:21-07:00
Hi!
I'm new to image processing in general, and newer working with ImageMagick. Thus, I lack the right vocabulary and skills even to ask here! So, please, excuse me if my question is too basic. I'm working in Mac OS X Leopard and Snow Leopard boxes.
I've being done bunch of tiff images from which I've to create web versions. Here an example:
http://ftp.ebiotic.net/onPdr/polboCropped.tiff
If I open any of this images with Mac OS X preview, I see it correctly. Something like this...
http://ftp.ebiotic.net/onPdr/polboCropped.jpg
If I use ImageMagick to see it (display polboCropped.tiff), I get this two errors:
display: incorrect count for field "MinSampleValue" (1, expecting 5); tag ignored. `polbo' @ warning/tiff.c/TIFFWarnings/704.
display: incorrect count for field "MaxSampleValue" (1, expecting 5); tag ignored. `polbo' @ warning/tiff.c/TIFFWarnings/704.
And see this...
http://ftp.ebiotic.net/onPdr/polboCropp ... isplay.jpg
If I save it, I won't get the errors again, but get the same image.
If I use Preview to convert the image in tiff format to jpg, I get a black/white picture... I don't know what is the problem here.. Something related to the Alpha channel?
Please, how could I convert these tiff images to jpg or png to diplay it in a website?
Thanks for your help!
