Though I have been an imagemagick user since some years, I only know how make simple processing with it. But now, I am facing a complex task (at least for me) and I'd appreciate some help for that. The documentation shows examples which I have studied, and I found a solution for eah single step. But I failed in trying the parenthesis feature to get to a one-shot processing.
I have tried with the parenthesis feature but had no luck.
So here is my problem:
- I have a starting picture with an un knwon size.
- The picture shall be resized to a defined width.
- A watermark from an individual text shall be overlayed at the bottom.
- A caption individual to thje picture shall be appended to the bottem.
For each step, I have a sample picture. I can however no show a 'real' "Step A" example sinve the upload-space only allows a width of 800 pixels.
This is the step A example. Due to webspace limitations in 800x size, so just assume1024x size instead.
This is the step B example. The same picture, but resized to 800x size.
This is the step C example. Now with an overlayed watermark.
This is the step D example. And finally with a caption appended to the south.
What I would like to have (and to understand) is a command similar to (just meta-syntax):
Code: Select all
$ convert stepA.jpg -resize 800x && \ overlayWatermark("with this text", size=800*0.9) && \ appendCaption("caption text", background=black, foreground=white, width=800px) \ into stepD.jpg
Any help is very much appreciated.
