Of course, you probably have much better and more interesting things to do with your time. It seems that the best way to include ChemDraw images in papers is by directly embedding them. The structures always appear crisper, probably because they are treated as vector vs. To create ridiculously oversized structures then save them as a high-resolution e. These never seem to look anywhere close as good, but I know of nothing better.

My art editor takes care of all the technical magic. For any image made in ChemDraw we insist with rare exceptions that we get the original ChemDraw file. We mess with that and make it look good and put it into our style.

Exporting to PNG with Transparent Background in Corel Draw 10

I think our production team then export as vector files eps from ChemDraw. Yeah, most newer versions of ChemDraw have it on as a default.

Older versions CD11 I think you had to turn it on manually. At first glance, sure, it seems like it would be simple. You need to get the font sizes right for the atom labels, not to mention the bond lengths. My hunch would also be to put it into a vector graphics format, then run some sort of script on it to rotate it. The hard part is doing it faster then you can draw the chemsketch structure, unless of course the paper you are working on has a dozen of these things, at which point you could probably learn the graphics format, programming language AND still do it faster then drawing these out in ChemSketch.

I just tried to generate one in ChemDraw after removing the fluff from around the edges and it told me there were too many atoms and gave me an error…. Oy… Reminds me of my own thesis, except we used carbosiloxane cores instead… Good luck with that! I thought of another way to draw then: There are a number of LaTeX packages to draw chemical structures. With all the symmetries involved, this looks relatively straightforward to do in Illustrator.

Just start with some end pieces and do rotate and duplicates with a typed in angle. Then group it and build inward. On the other hand, Illustrator costs a fair bit, so it would pay to try out Intaglio or the like, or see if you have strong LaTeX fu.

I would say that the trouble with chemical drawing packages is the lack of a means of calculating and typing in rotations and displacements with duplication with respect to reference points that are not necessarily chemically significant. There was a built-in function for duplicating an object evenly round a circle.

Also I got fed up with wordprocessors and did the huge latex download. Latex likes EPS.One of the attractions of Applescript is that it helps with the automation of repetive tasks. I was recently asked if I could help with a script to convert ChemBioDraw. The script below automates this task, I actually wrote it as a droplet so you can drop a bunch of cdx files on it and it will convert all to PNG format saving all the new files in the same location as the original, keeping the same file name but changing the extension to.

If you wan to see the display dialogs that I have commented out simply remove the "--" and recompile, it is perhaps easier to undertand what is happening. With a list of source files the repeat loop takes each file and determines the file name, extension, type and kind. These are not all needed for this script but it is helpful to know what is what.

The "trimmed name" is the file name without the extension, trimmed path" is the full path minus the extension. We then construct the new file name and path.

How to Save PNG or JPG for Web

Since ChemBioDraw scripting only seems to support saving to an alias we create an empty file using write to file. ChemBioDraw Note apparently there is a bug in older versions of ChemBioDraw that prevents save to PNG, updating to the latest version solves the problem.

The droplet can be downloaded from here scriptPNGapp.I'm trying to cut a part of a picture in Photo Paint. This is working so far. But when I try to save only this part of the picture with a transparent background, it always tells me that the object is combined with a background when saving. No matter what Im doing it doesnt work. The background is always white or grey. I think you are starting with an image that does not have a transparent background. I got that far.

I can even export it to Corel Draw and there it has the transparent background. But I need it as a png for an other program.

First, check in object manager. You should see your design as an object with a checkerboard behind it :. The problem is that background layer.

If you have a background layer, you must select it, right click on it and delete it:. All rights reserved. The content herein is in the form of a personal web log "Blog" or forum posting.

The following image types are supported:. Using the ChemDoodle. The following examples show how this is done. This is done by calling the ChemDoodle. Keep in mind that PNG is a bitmap format, so the string will be represented as Base64 text so you can use it in web pages, which will be text based. SVG is a scalable vector graphic, and can be increased in scale without loss of resolution, as the next comparison shows. SVG export can only be performed on 2D Canvases.

Note that the ChemDoodle. About What is ChemDoodle Web? Advantages Desktop Solutions Questions? The following image types are supported: Portable Network Graphics. Web Scalable Vector Graphics.

If you're working on a Mac, I have good news for you. As part of an iPhone chemistry application my company is helping to develop, we needed to convert a large number of CDX files into PNGs.

Read on to find out how we automated this process and saved a bunch of time. ChemBot is a small Mac application written in AppleScript. It can be downloaded from GitHuband the source code is also available there.

ChemBot requires ChemDraw Ultra Although conceptually a very simple piece of software, one of the hard things about creating ChemBot was the surprising scarcity of real-world AppleScript examples. Our starting point was Chris Swain's excellent AppleScript tutorial series. Although it wasn't quite what we were looking for, it was a start. After some experimentation, we hit a major problem.

Chris Swain very quickly came back with an answer to my email: ChemDraw apparently can only save images files to an existing alias. Attempting to save to a filename that doesn't exist won't work. This approach has the advantage of working on Windows. AppleScript is a useful piece of technology, although good examples of its use are in short supply.These guidelines are necessarily quite technical, and are intended for editors with some experience of drawing chemical structure diagrams and reaction schemes.

For a less technical overview of the issues involved, see Wikipedia:Molecular structure diagram. ACS templates are available in most chemical drawing programs. Note: Accelrys Draw 4. Image file may be generated by using MS' Copy feature, followed by a Paste into another program. Photoshop Elements or Paint may be used. The image can then be saved as a. PNG file. A further possibility in Windows is to use the Shift-PrtSc key combination to copy a screenshot into the copy buffer.

Paste that into MS Paint and crop it. The same link as IsisDraw will allow a free download of SymyxDraw 3. There is a free, open source program called BKchem.

CORINA online is an easy to handle 3D-model generator of molecules, with the objective to execute the structural determination within a particular low time investment.

This advantage is bought by a divergence from the ideal geometry. For instance, the program works with presets. To which extend these divergences are tolerable depends on the individual case and on quality demands. Pseudochirality centers may turn out as pitfalls e.

Most molecule editors cannot produce. PNG images directly with the requirements outlined above. The image processing step also allows a canvas margin to be added this is usually absent from the molecule editor output. SVG files are preferred, because they are smaller in filesize, can generate high quality images for printing and are easier to translate if text is added to mechanism.

ChemDraw exports svgs with a white background. Another option is to open the file with Inkscape, right-click on the structure and select "Ungroup", then click anywhere on the white background and hit delete, then save again.

There tends to be an unreasonably large margin left around the diagram's extents, so it is often a good idea to crop the image in a vector program such as Inkscape before uploading it. Leave a small margin of 1. This method works only if your molecule editor is able to export files in Windows Metafile format. For example, ChemDraw supports this, as does ChemSketch. Alternative but little more complex way to generate high quality and small size SVG files.

However, note the following issues with Mol2Svg:. Please upload images to Wikimedia Commons and not to the English Wikipedia. This enables images to be used in other Wikipedia languages and other Wikimedia projects and makes updating images much easier, it also saves someone else having to move the structure to Commons later.

It is also simpler to find images in the Commons category structure compared to Wikipedia. To upload images to the Commons, you must be a registered user there.

I am making a pair of shoes on another website, and I need this image as a picture for the shoe, but no matter what I try, the image always saves as a white background, when all I want to save is the picture itself WITHOUT the white background. If anyone could help, I would really appreciate it. Thanks in advance. JPG does not support transparency - it gets converted to white.

Can't save as png with transparent background

You need to save in a format that supports transparency, like PNG. Also make sure when you are making your image, you delete the background before doing anything, otherwise you're still working on a white background.

I was also wondering the same thing but could one of you go a little bit more in depth of exactly how it is all done? Like, how do I delete the background and everything else I gotta do. I would really appreciate this because I have a project coming up in school and I need to know how it is done. You can post now and register later.
