Oval PAD shape incorrect in Export I Made this component for a switch I use. Whenever I make components I like to print out a 1:1 to test before continuing. I noticed that when exporting the PADS swell excessively. Steps to reproduce bug: 1. Change PAD to oval The attached images show using round rectangular and Oval The Round Comes out correct. The Rectangular is correct. The Oval is too large I have tried with a slot and with a hole. I have tried various combinations but always get larger when printing (export) Results: ![What the PDF file looks like][1] Expected results: ![What I expect from photo view][2] ![What it looks Like in PCB editor][3] Browser: Chrome https://easyeda.com/editor#id=509936274db5436291dd72c1a27fdf77|3393824ffcc24614bbfd0130e38f1aa5|_41db11bb9e64408f8af2f1150bd9299f|_b2b42447b14a4a739e1e52a073bdf5ba|_0ebd813223704c2d9deab1e23739eddd|_2d1b81acef464f128bc9b9034fc89bb0 I am fairly new to Easy EDA but not to PCB design. Am I missing something or is this a bug. My project should be public. [1]: /editor/20170424/58fdc6bfd8579.png [2]: /editor/20170424/58fdc675221f4.png [3]: /editor/20170424/58fdc705cda0d.png

Hi Jonodug, Welcome to EasyEDA. This is a known bug. All effort is focused on the Desktop version of EasyEDA at present but it should be fixed soon.

I'm having this problem too. Is there a bug tracker where you can follow the progress? Or just get a message when it's fixed? Other than that, this is an amazing tool!

There's no publically available bug tracker for EasyEDA.

@Hassanbot, After you click on `Fabrication Output...` in the PCB Editor: ![enter image description here][1] you can check your Gerber files by clicking on `Gerber-viewer`: ![enter image description here][2] Or go to the Gerber Viewer directly: https://gerber-viewer.easyeda.com/?ref=easyeda.com#!id=42cc1003299611e79ed5026a86b9cae7 [1]: /editor/20170425/58ff19d855781.png [2]: /editor/20170425/58ff10bc129f7.png

Thanks a lot! Do you know of a tool to convert Gerber files to negative image for toner transfer PCB etching?

I think there is a way to do this using the EasyEDA Gerber-viewer and the FOSS Imagemagik program. The technique I describe below does not work properly because the results are very coarse but I think it may be possible to refine the process in some way to correct that. The basic idea is this. First install Imagemagik: http://imagemagick.org/script/download.php If you are running Linux, it is probably already installed. 1. Upload your Gerber to the EasyEDA Gerber-viewer; 2. Select only the copper trace layer (Gerber_drill.GTL); 3. Click on `Export Image`; 4. Right-click on the image that opens in your browser and select `Save image as...`. This saves the image as `download.png`; 5. Open a command window; 6. Navigate to the folder that you have saved the `download.png` to; 7. Run the command `convert -negate -monochrome -negate download.png download_neg.png`' This generates a white = copper, black = no copper image. I am not familiar enough with Imagemagik to know how to improve the image resolution.

@andyfierman Thank you for The info. Looking forward to seeing what the desktop version can do Been really enjoying the online version so far. Will work with the trouble. Thanks

@Jonodug, There's a *much* easier way: Install a copy of the FOSS gerbv from: https://sourceforge.net/projects/gerbv/files/gerbv/ 1. Open the layer (File > Open Layer(s)) you want to negate; 2. Either press `F6` or, in the left hand panel, right-click on the selected layer and click on `Change color`; 3. Set the colour to `#FFFFFF` (white); 4. In the left hand panel, right-click on the selected layer and click on `Invert color`; 5. `File > Print` (CTRL+P); 6. **OR** `File > Export`, select the output file format then select where to save the file and enter the desired file name **including** the relevant suffix such as .png or .pdf.

Should have said: 1. Download and then unzip your Gerber file and then in gerbv, open the layer (File > Open Layer(s)) you want to negate;
