I need a method of placing a smaller image onto a bigger one in a specific place. Doing this over and over again is tedious. I need a script to do this for me since for some reason or other image placeholders aren't (as far as I know) built into photoshop
Thanks

I'm making a poster (sort of) and would like to do these things, but I'm not sure if AsciiDoc or AsciiDoctor can do them, and if so, how:
Background image that can be stretched to the poster's dimensions
A rectangle with some transparency and a border, basically a bright frame, with text in it.
An image with text in it.
Text inside an image inside a rectangle.
(Bonus question: Is it possible to free-form specify where something goes, e.g. x=80%, y = 20% for something in the top right corner?)
I'm not sure that it makes sense to use AsciiDoc to source poster output, as opposed to a desktop publishing tool or a graphics program.
But if you are converting to HTML, you should be able to accomplish most of this with clever sourcing and some CSS/JavaScript on the front end. That is, you can source some of the metadata you want to impose on the final image, then have front-end code do the manipulation and imposition. For instance, you can provide a caption, classes, a title, and other info in the source, but AsciiDoc is intentionally agnostic about how that stuff is handled in output.
However, unless you need to create these things as part of technical documents, especially ones getting built/generated recuringly with automation, you're likely better off with a specialized tool.
Say I have a range – something like a 400x400 rectangle at 60, 60 – which is dynamically generated by a separate program. I'm wondering how it's possible to crop my document to that range in the command line?
Everything I've read has suggested I'd need to add a rectangle to the document, resize the document to that rectangle (resize to selection), and then remove the rectangle.
But I'm having trouble with adding and removing that rectangle. I found the ToolRect verb, but I can't seem to find anything related to actually drawing that rectangle (or removing it).
So, am I doing this wrong or is there just no way to add (and select) the rectangle using only the command line? Using another program is also fine, but I haven't had much luck with that (I couldn't get the python modules installed for the only possibly helpful thing I found..).
In this email discussion from 2012, someone said:
There is no way to pass parameters to verbs (with the current
implementation, they don't take parameters by design).
In case they add this capability later, the required verbs to crop the page would be:
EditSelectAll
SelectionGroup
ToolRect (requires parameters, i.e. where to crop)
EditSelectAll
ObjectSetClipPath
FitCanvasToDrawing
FileVacuum
FileSaveAs (requires a parameter, so that we don't have to overwrite the original)
Since Inkscape can edit any valid SVG, I'd rather look into other available SVG libraries, like this one for Python.
If you are OK with rasterising your image, take a look at this question. Inkscape unfortunately ignores the --export-area option when exporting to svg or pdf.
My – admittedly, unsatisfying – solution was to create a separate program to add a viewbox to the SVG text.
The program I made was implemented into a separate part of my project, so I don't have a good command line version, but if you plan on making one yourself, whatever XML editing library you have for your language of choice should be all you need. I used xmldom for Node.js with relative ease.
The VS2010 image library contains several pngs of standard icons (Warning, Error, ...) in different sizes side by side. What is the use of such a png?
Is it meant as source to cut the best size and save it as new png?
Or is there a way to use such a png and the best resolution is picked automatically. And if so, how is this done?
I wonder why there are such side-by-side images and not several files such as Warning32.png, Warning16.png ....
Example: Information.png
It is an old programming trick and it is exactly what you assume it to be. The bitmap is a "film roll" and to make it work you have to know the pitch of the images, the resource doesn't tell you. Hard-coded in the source code. Microsoft's source code, you got the copy of their work.
I need to develop a desktop application which will
1.) have a list of the Different Application logos (Background Transparent) e.g. IE, FIREFOX, CHROME, PHOTOSHOP ETC.
2.) User will take a screenshot of desktop and save the image.
3.) Now my application need to search all the logos in the screenshot image and tell which all logos are present and where.
4.) I used OPENCV, it's working, but when user changes the desktop background & captures screenshot, it's not working as the transparent area of logo is getting the desktop background content.
Can somebody provide a solution or libraries open source, commercial to do this job.
This is easy to do using cross-correlation.
See my answer to this question.
Basically:
Start with desktop image and one template image for each icon
Apply edge detection (e.g. Sobel) to the desktop image and template images.
Throw away the original desktop image and templates, you won't need them anymore cause we'll be using the edge-detected images
For each template
Do template matching as you normally would
Threshold the maximum of the result. If it's above the threshold, you have a match at that position. Otherwise, no match.
If your icons are aligned in a grid on the desktop, you may be able to speed up your processing by only checking those specific grid positions.
EDIT
You can also save a lot of time by knowing which icons to search for. If you have access to the file system, then just look for *.lnk files (or any other extensions you may be interested in) in the directory that corresponds to the desktop (can't remember exactly what it is, but for Windows7 it's something like c:\users\misha\desktop). That will tell you what icons are there on the desktop. This will allow you to shorten your template candidate list before you go and do the template matching.
I like misha's answer and I think it should work for you. But it that doesn't work you could try replacing the transparant pixels in your reference logo with uniformly distributed random noise before trying the match. This will make the transparant pixels irrelevant for any matching computation because they will match just as bad no matter what there is on the desktop in those pixels.
I'm not familiar with the tools you're using, but I'm guessing you have to either:
a) Tell your program to ignore transparent pixels in the icon images during the comparison operation.
OR
b) Tell your program to treat transparent pixels in the icon images as "wildcards" which can be any color.
I have a set of really big images out of which I need to crop little snippets. These snippets are all exactly the same size but don't follow a strict pattern so I can't do this programatically.
Ideally I would like to open up one of the big files and be able to point and click on say, the top left corner of a snippet and have that automatically be saved to disk without even having to enter a file name, and then continue on with the rest. (Of course this would be the ideal way which I know is probably way off the real possible way!).
I started doing this in Photoshop CS4 but cropping a snippet, saving, undoing (to get to the full image), and starting over again takes way too long.
Maybe someone has a better way to do this in photoshop or in some other software.
Thanks for reading!
Instead of cropping and undoing, you could:
make (or resize) a selection
copy the selection to a new image
save the image
close the image
You might need to split it into two actions, I don't know enough about programming Photoshop.
Thank you everyone for your input.
I ended up doing this with a suggestion a colleague of mine came up with. It consisted of creating a Photoshop "slice" over the first region I wanted to crop and then cloning that region over the rest of the other sections. After that, using Save For Web (and ofter hitting Continue when PS complained about how that image was way beyond Save For Web's capabilities) I could save all images at once.
This was the fastest and easiest method I could find. Until then I was going with Mark Ransom's method.
