CorelDRAW Graphics Suite X6 :: Conversion Of CDR File
Nov 9, 2012
I'm writing an application in C++ that loads vector images from a source directory and convert them in bmp or other non vectorial format in the destination directory. I need to load CDR file also, but unfortunatly I can't find a documantation regarding the proprietary CDR file format.
Of course, these informations aren't published by Corel that maintain the secret of the format. But my question is: does Corel sell some SDK that provides some functions, callable directly from the source code written in c++, that permits the conversion of the file?
I have been trying to find a solution to this for a couple days now. The problem is that when I convert my EPS and WMF files to JPG the results look bad. I've tried multiple programs and multiple methods. The only way I get good results are if I open the file in CorelDraw, import as curves, and Export For Web to a JPG. Otherwise, the output jpg file looks low resolution. I have thousands of EPS and WMF files that I would like to convert to JPG. Again, I can use a batch conversion program like FastStone and the results are poor.Is there anyway to automate the high quality conversion?
As standard pallette we use Pantone Coated, but after I export a .cdr to .eps some colors are replaced with a new color with the same name, when I open it in Coreldraw again afterwards. The colors are placed in a new user pallette and have different CMYK values.
Importing a file in RGB and converting it to CMYK values are different estremamante performing the same operation in photoshop. The setting of the color profiles is the same and also varying the options Microsoft ICM CMM in color management, keep varying the pure black and gray to black colleague CYMK, does not improve anything. The conversion in coreldraw is too much dark and this is a problem. How is it possible?Here the setting of CorelDraw and Photoshop.
I'd like to create a vector graphic with precise object size and placement so that when I import into PhotoPaint I get a precise conversion.
For example (use no outlines):
make a black square 10mm in diameter create 9 colored squares 2mm in diameter placed 1mm from the edge of the black square and 1 mm from each other copy all your squares paste into photopaint setting size to 10 pixels square and turning anti-alias off what you get is not what you drew in corel draw
Here's my example as a vector:
and as a bitmap:
So the squares are completely the wrong size - 1 pixel larger than they should be and in the wrong position!
Interestingly if you import the same vector as a bitmap 100 pixels square it looks better - however you'll notice that the colored squares are, in fact, 21 pixels square and not 20!
The conversion process seems to make every object larger by one pixel in each dimension - not useful. I should note that this effect happens in X5 as well.
In 2006 I started a vector-based comic using CorelDraw, made for posting on the web in RGB. Over the years I've made the transition to a more CMYK-friendly palette that works on the web, though a handful of heritage characters still have the old RGB profiles. I'm looking to do a book collection now and, as such, want to convert these characters' specific colors to their fitting CMYK counterparts.
Is there a batch process that allows me to convert a specific handful (maybe 2 dozen) colors RGB --> CMYK across a number of files? I'm looking at hundreds of pages of artwork here, so even Corel's Object Find/Replace would be a tedious slough.
Recently found another bug in X6. This time it is in the Pantone conversion tables when converting to cmyk. I had a job that had been updated over the years and the file was last used in X5. The colour in question was PMS 7406. The file opened fine & was converted to cmyk and sent to the printer unchecked. What could possibly go wrong - this file had been used countless times before without incident. Pantone 7406 breaks down to 18% magenta and 100% yellow (as per Pantone's own specification). X5 converted it to 17% magenta and 100% yellow. Near enough - I'm not going to quibble over 1%. However, opening the X5 file in X6 caused it to use the 'Pantone previous version' colour table (and you don't get any notification that it is doing it). Result is that it now converts the colour to 18% cyan, 24% magenta and 100% yellow. Where the #@**# did it get the cyan from? We are now talking about a completely different color!
It gets worse. If you create a new object in X6 and fill it with PMS 7406 (using the Pantone + colour table) and then convert it to cmyk, you get 6% cyan, 22% magenta and 100% yellow. Again, this is not the correct break down of this colour. Pantone is a world standard with known conversion to cmyk figures. InDesign can get it right, Illustrator can get it right, then why can't Corel? And how many other Pantone colours are wrong? I have used Draw for 20 years and this is the worst bungle yet (apart from version 4). For a program that tells the world it is a professional program to screw up like this beggars belief.
If we have to check every single Pantone to cmyk conversion against the Pantone specifications, then it just isn't worth using Corel in printing. Add this to the font problems in Font Navigator and the scale error in Barcode Generator and it make X6 pretty much useless in the print industry. Throwing in freebies like fonts, second rate web creators and Photo Paint are not much use when the flagship program is sinking.
I have some Ai files that I need to open in X6 but they use linked images which I have, but when opening in CorelDraw all I get is the basic Ai stuff but not the linked images, is there an easy way to open the Ai file and see it as it was intended?
As a sub note I can't go back to the supplier of the Ai file to make any changes.
I just used the help file for the first time in ages and noticed all the links to the graphics are broken hence no diagrams etc. I tried to search out where they are usually stored and it gives some weird Address under properties. It's a vba so suppose it's a database? How do I restore the links without having to do a re-install?
As to the pen: How do you stop the annoying over-the-top predictive curve that happens past the node in the next section after a long drag to form the first curve. i.e. you simply want to draw a straight line after dragging out a curved section previously and you get this unmanageable curve to deal with ?
I´m trying to extract text from a Corel file to a TXT file in another editor and then merge it back in.Extracting the text seems to be working just fine but when I´m trying to merge it back in I get the error message "Wrong file format or could not open".
After finally getting X6 to be stable and usable I have two things I'd like to mention..
First, I've been using a 3rd party file manager called Ztree for years and one of its most wonderful capabilities is to copy paths to the clipboard which alleviates opening/saving frustrations with the typical Windoze Explorer dialogs. Anyway, one of the first problems I noticed with X6 is that Paste no longer works in the Open Drawing dialog, while it worked just fine in X5 and as far as I can remember, all previous versions. I sure would like to get that back.
My second complaint is the File/Export routine and specifically the presets. I do a lot of exporting to PNG and JPG and use multiple presets for fixed size/print resolution image output in both file formats. During the typical export session, I essentially export multiple different drawings all of which are exactly the same size/resolution in CD and in the past (X4 and prior as I recall,) was able to just hit <Enter> when the Export dialog appeared once the preset was set to the one I needed for that session.
In X6 though (and to some degree in X5,) even though the correct preset is listed, CD doesn't appear to recognize it, i.e., the math for the size/dpi conversion doesn't take place which forces me to waste time selecting "Original" or some other preset first, waiting for CD to render the new version, and THEN selecting the conversion preset that was pre-selected when I first opened the export dialog.
I have a bitmap in PSD format with 300 DPI, 19.0 cm (7.0 ") wide. I need to enlarge this photo to 6.5 m (255") wide and its resolution to keep a minimum 120 DPI.
What better way to enlarge this photo without becoming a huge file (in MB), but keep a good quality when printing?
Q When I import an EPS file into CorelDRAW, and print to a non-PostScript printer, the output appears pixelated and unclear. Why?
A An EPS file is a Postscript (PS) file and meant to be printed to a PostScript printer. When printed to a non-PostScript printer, it will only print the file header which is a low resolution preview of the actual file. If you wish to print the actual contents of the EPS file to a non-PostScript printer, import the file it into CorelDRAW using the PostScript Interpreted (PS, PRN, EPS) filter.So, apparently it can be done, but when I try to import this file into my Coreldraw, there is no option to import with that type of filter that I can see. Is this something that is missing in v12? If v12 wont do it, is there any other way to import this file without it coming in all pixellated? Or is there another way to convert the file into a format such as .plt?
I am new to Corel Draw and am slowly teaching myself. I created a drawing in Corel Draw and then exported it to DXF. I then opened them in a CAD application to actually cut the image out in a water jet. The size of the drawing was not modified, only the corners were fillet (because I could not figure it out in Corel Draw at that time). When I imported it back into COrel Draw to fill it with my image, the size of the drawing was about a 1/2 " bigger (width and height) than it was when I exported it. This is the only place where the size is different.
I am creating a menu for a cient as a PDF. When I open it up in PDF format it is too large (174%) to view each page individually. It works well at about 75%. Is there a way I can have it open up at 75%?
I am trying to upload a file for a microstock site that requires an eps file under 8MB. As a cdr file, it is under 25KB but when I export the file as an eps it rockets to over 400,000KB.
I have several Coral Draw-12 files saved in a particular folder. The problem is when i am trying to open a particular file it's fine but, when trying to open a second or third .cdr file (with the first file opened) from the same folder it' s not opening.
i have a problem with CorelDraw X5where the file i open is bigger than A4 and on a custom set page size. and it opens like this.and in signcut it is
i need to edit the file and i dont know why coreldraw X5 is not letting me view the entire file. How i can overcome this or if there are any settings that i may have chanced of hot key shortcuts that i could have pressed by accident. also i have been using draw x5 for about a year put i only use half the program for what i need it for.
Running CorelX5 on windows 7 - On my work computer when I have a file open and hit the save button I'm getting the message "can not save, file is open or being used by other program". I have to save as a different name. I assume another program is to blame and is associated with .cdr.
I have been using Corel since 1989. I simply downloaded a pic from Corel gallery and even removed C15 many times still no joy. All hundreds of files are effected..
I have posted before about not being able to open X5 and receiving a "Coreldraw has encountered a problem and needs to close." error message upon launch. I have not been able to resolve this issue.
I have to work on a graphic file and need it converted top X3 (this version opens) as it was created in X5.
I made a file in coreldraw x6 and unintentionally opened in corel X5. Obviously it didn't open. But apart from that, the file neither opens in corel x6 now!!!!
It seems it cant be opened or something like that. But anyway it still sizes 2,94MB, so I am hopeful to recover it.It was a lot of work for me wasted. I tried to convert it to x5 format in URL....
