I have to slice from "cdr" file to HTML. I search on the web, but i didn't find anything on how to do that.
Does anybody know a tutorial on how to slice from CorelDraw to Html?
It's that even possible or should i convert it somehow in PSD?
Thanks.
Go to file->export->and select psd option and export it, and slice the images using photoshop then use it in html.
If you need layers , go to corel draw tools ->object manager there you have arrange your design in layer format then export it.

I want to make a steganographic image using some very simple software. I want to demonstrate the principle by opening up a bitmap image file in an editor that will let me see the binary that encodes the colours of individual pixels. I want to change the last couple of bits for some pixels to hide my secret binary message, then re-save the image. I have seen that there are a few applications available that can create steganographic images, some of which are free, but they seem to hide what is really going on. I want to see and edit the 'raw' binary for myself. I hoped something like Notepad++ or Cyberchef would let me do this, but apparently not. Can you suggest something I can use please?
I am developing an application that generates images from certain input data through the command "iup.image" and "iup.SaveImage". Now, I need to read this image file again and retrieve the pixels.
I found the command "iup.LoadImage" but I could not find a way to proceed. Can someone help me? I am using LUA language by ZeroBrane Studio.
The pixels of an IUP image can be accessed through the WID attribute in C. IUP images are designed to be simple resources used in buttons, labels and other interface elements.
If you want to manipulate pixels in Lua you should use IM directly. You are already using IM underneath when you call iup.SaveImage and iup.LoadImage.
With Photoshop I have multiple web banners at different sizes that contain the same image. Is there a way to change the image on one psd file so that it will automatically change on all the other psd files?
I'm using Creative Cloud
Any help will be really appreciated
Thanks
Create the banner in the biggest size
Right click the layer and choose Convert to smart object
Create a new document with next banner measurements. Go back to the already created banner and use the move tool (v) and drag the layer/layers in to the new document.
If you now doubleclick your smart object (doesnt matter in which document) you will open a new document. If you make any changes there it will be changed in both banners.
You can choose more than one layer to become a smart object together. When you double click the smart object you will find all your layers separate but in the banner document it will only show as one file.
This is what the symbol on a smart layer looks like
One option is to use linked smart objects.
If you have photoshop CC you can follow this for instruction on how you'd do it.
(Sorry for the link only answer but it's a video and will make more sense then listing the steps)
if you use Photoshop CC 2014 or 2015 you can place images as linked files, same way as InDesign or HTML docs. Adobe gives now two choices Place Embeded or Place Linked.
I'd like to an an image (ideally an SVG) as an inset to an existing graph in R and put a black border around the image.
Is that possible with base-functions in R? Do I need packages for that?
Maybe the grImport package is what you are looking for ? It only seems to allow to import Posctscript files, however.
You can find two vignettes files on the package web page, which should help you learn how to use it.
Convert your SVG to PostScript, then you can do all this good stuff:

If there's an easier way to convert from SVG to the RGML format mentioned there, that would be a better option.
I've read much about PDF extractions and libraries (as iText) but i just haven't found a solution to extract images and text (with coordinates) from a PDF.
The task is to scan PDF with catalog of products and extract each image. There is an image code printed next to each image and also a list of product codes for products that are shown on the image.
I know that there is no way to extract structured info from a PDF like this but with coordinates of all image and text objects I could write code to identify linked text by its distance from the image. Then I could split text using a RegExp and find out what is a product code, what is an image code etc.
Could you recommend a good and working solution for the task?
Use XPDF (http://www.foolabs.com/xpdf/)
It can extract all the characters in the PDF with co-ordinates (pdftotext -bbox [sourcefile] [outputfile]) and also all the images and SVGs in the PDF.
It's open source (GPLv2) and supports a lot of additional extraction functionalities as well.
Several Java libraries can do this. Have you looked at JPedal or PdfBox?
If a commercial library is an option for you, you could try Amyuni PDF Creator .Net or Amyuni PDF Creator ActiveX. You could use the method IacDocument.GetObjectsInRectangle to retrieve all the "graphic objects" of your interest, then use the ObjectType attribute to separate images from text. The library already provides an algorithm for putting close text together. From the documentation:
IacDocument.GetObjectsInRectangle Method
The GetObjectsInRectangle method gets all the objects that are in the specified rectangle.
