i uploaded some examples and a explanation onto dropbox

hope i managed to explain the issue

thanks for the replies,

the corrrection data is generated external and the parsing/extracting of the textfile in bash (which is the used language) is no problem.

In step 4 as i wrote the image should be cropped and the challenge for me is that the images after removing the edge triangles have ...

Hi,

following challenge:

in order to "stabilize" a series of n(48) images taken in a circle around a object, in a directory there is a textfile corrections.txt with n(48) lines containing XOffset;YOffset;DegreeToRotate for each image. The content of corrections.txt is manually generated correction ...

thanks for your replies guys, the reason why i think i do need a downscale and not just crop:

when just cropping to 1920x1080 after +distort SRT, the result will not have the full width of the source image (2256) which i want to keep at "zoomfactor 1", so i have to crop to
2256x1268 (16:9 aspect ...

the starting image has the correct aspect ratio (16*9) and resolution > fullhd, my final images should have full HD resolution.

while the source image is bigger than 1920x1080, zooming in is equivalent to cropping a area and then downscale that result to 1920x1080.
information is lost only during ...

thanks for your reply but the geometry argument without offsets doesn't work, i think its best if i explain in detail.
it starts with https://dl.dropboxusercontent.com/u/341424/test.jpg which has 2256x1504px

cropping it to 16:9
convert test.jpg -gravity Center -crop 2256x1286+0+0 +repage zoom.jpg ...

the resulting images are used for a movie afterwards, so i will go with "-distort SRT".

The problem i want to point out is, that for the first zoom levels cropping a smaller 16x9 area of the 2256*1505 image and downscaling to 1920x1080 would be enough - up to the zoom level where the cutout would ...

Hi,

i have to process a bunch of images from a digital camera at 2256x1504 and zoom into them while the output size is always full-HD (1920x1080).

What i want to archive is the maximal quality so when the zoom factor is 1 (none) the Image should just be cropped to 16:9 cutting on top and bottom ...
