converting an image to cmyk bitmap increases its initial size. it's happening in corel x4 only.... is this a bug?
It is not only in X4. CMYK will always be bigger than RGB encoding. You get a wider range of colour using CMYK. CMYK is 32 bit where RGB only goes up to 24 bit, resulting in a bigger file.
i was not referring at the file size. i was referring at the bitmap dimensions in mm.
hunter, i'm sorry but i`m using coreldraw from version 12. i know what's dpi, what is an inch and a mm and all that.. but all of my work is done for print (not for web) so i never used and i`ll never use pixels as a unit of measurement for bitmaps.
if you could just try what i've said earlier this day and i think i was making myself pretty clear... you will see that there is this bug that i'm talking about.
pick any kind of bitmap/jpeg/tif/whatever you want and import it in x4. convert it to bitmap at 72/100/150/200/300/600 DPI or any other print resolution and you'll see that the bitmap increases its dimensions.
anyway, this thing above all the other very very serious and BIG bugs is enough.
one more thing i discovered, the coordinates do not update after moving an object, you have to reselect that object to see the right coordinates. i'm just tired of seeking solutions, cause i think it's useless, x4 it's just way too buggy and i decided to skip this release.
one thing i just don't get and i'll never understand is how (how??!) the developers released this as a final version product with so so so serious bugs :( i mean before releasing this kind of program, (or any other program as a matter of fact), don't you guys test it first? i mean basic tests, because having it crashed each time i work with paragraph texts is unacceptable for such a program! totally unacceptable!
how can i work with pixels if i want my image to be exactly 7/10 cm when printed? i'm working with milimeters. i design brochures/flyers/posters in milimeters not in pixels. why convert pixels to mm?!? i'm sorry i think i'm not yet understood here. maybe it's my english or something
just tried with PIXELS.. totally useless but just for you to know: SAME PROBLEM THERE! bitmap increases its size... but now IN PIXELS!
thank you for your time explaining all that to me. understood the relation there.
why doesn't this happen in previous versions?
if i were to draw a simple square 2.00" by 2.00" and convert that to a 300dpi bitmap, in x4 results a 2.01" by 2.01" square. but in corel 12 it results the same dimensions: 2.00" by 2.00"
was that an error in corel 12? and is now corrected in x4?
i always work with 2 decimals. i just tried this with 3 decimals precision and here's what i get by converting that 2.000" by 2.000" square:
in x4 --> 2.011" x 2.011"
in 12 or x3 --> 2.003" x 2.003"
ok, so i get different results. why that difference? this bugs me. now i know that because of using only 2 decimals i didn't notice the increase in size, because there wasn't any... practically speaking, but in theory like hunter said, it's there.
well, now i only want to say is that i prefer the old formula for calculating this conversion
referring to paragraph text crashing: crashes everytime when working with imported/pasted text from anywhere else but corel. not machine/fonts related. i tested this on 3 different machines including one in vmware which i keep absolutely clean (with no extra fonts nor apps installed) just for doing these tests.
yes you are right and i thought of this, so i`ve just converted now that hairline outline to an object. and so the 2.000x2.000 becomes 2.003x2.003 inches. converting that to a 300dpi bmp adds up another 0.003 inches.
actually i'm using powerclips to solve this, but when i have multiple bitmaps/objects it's very time consuming... but it solves the problem.
thank you once again
I work with metric units and because I am a graphic designer, also don't like working with pixels for desktop publishing but for my web images, I switch to and from mm/px frequently. I think maybe all this confusion started because Kenner noticed in the sizing that there is a smaller than a millimeter change when converting to bitmap which was not in previous versions, after I understood what Kenner meant, I saw it too BUT in previous versions of corel, when working say in mm's, when making a bitmap 300x300dpi for example, the finished bitmap showed maybe 300x299dpi. Now that you can't see the dpi in the bottom of the status bar but see the size changes in mm/inches, it creates confusion. Although it is not THAT big an issue because the size change is so minimal, it is barely noticeable and like Kenner said previously, when not using anti-aliasing, the size does not change... but it definitely has an inpact on the quality of the image's edge.
Basically, I do not think we need to break our necks and freak out because of a dot or two, like you said Kenner, there is always powerclips (and I for one LOVE them)
