How do i edit an image size by pixel. I need to create a banner that is 800 by 135 pixels (so it can be stretched).
Thanks
 
Are you wanting to resize your paper or your image? To resize the image double-click the ruler and change it from inches to pixels. Now with your image selected choose your Node edit tool. You may have to pull the top two nodes down or the two side ones in to get the image sized the way you want. Don't ever "stretch" an image. This is one of the biggest mistakes people make. Unless, of course, that is the desired effect you want.
 
Hi, sorry to say this but I keep on seeing people using vector tools to try to create rastor images. Its like trying to tighten a bolt with a hammer and chisel, you can do it but it may not look very nice afterwards.

For buttons or Banners you are better off using corel paint or my favorite (and the majority of the planet) paint shop pro( downloadable as a trial.

These allow you to put text and other objects onto the screen and move them around until they look right, and make pixel by pixel changes, and what they look like is exactly what you will get as it only works at a pixel level.

Bolts... hammer and chisel, great analogy. And so true.

I prefer to create graphical objects like banners an buttons in a vector base program like Corel Draw, save the original and then export into raster format. If I want to resize or otherwise edit any element of the banner it can easily be done. Resizing a vector image is a piece of cake. Resizing a raster image causes pixelation. Here's a little background:

Raster Image Formats
Raster format breaks an image into a grid of equally sized pieces, called pixels, and records color information for each pixel. The number of colors that the file can contain is determined by the bits-per-pixel: the more information that is recorded for each pixel, the more shades and hues that the file can contain.


Meta and Vector Image Formats
Meta and vector image formats can both contain vector data. Vector data is a collection of geometric shapes that combine to make an image, recorded as mathematical formulas. Vector data cannot reproduce photo-realistic images, but for other types of images it has two advantages over raster data: it is scaleable without distortion (the "jaggies" that come with re-sizing a bitmap), and it produces smaller files (generally speaking).


 
nullgod, what is so hard about creating a rastor image in CorelDraw. Create a vector, then export it as a jpg or gif, there's your rasterization. CorelDraw is excellent for creating Banners! Size your page exactly to the size you want your banner to be and start drawing or importing graphics as needed. Why would anyone want to rasterize a perfectly good vector anyway? Vector prints a lot better.
Now, back to the original post. What I see often is someone wants to take an image that is, say, 5"x7" and resize it to something odd like 2"x24"(banner). Sure you could stretch it to fit, but it's going to be so heavily distorted that you won't be able to tell what it is. You have to crop the image somewhere and nine times out of ten it will crop more than is desired. Wait a minute, are we talking about a "banner" for a webpage?! Is this why taliesun wants pixel height and width? If so, I must still refer to setting the rulers to pixels instead of inches and then moveing the nodes of the image around then dragging the corner selection handle to reach the desired output.
 
Hi again, dont get me wrong, I love Draw with a passion, having used it for the last 6 years for all my publishing needs, designing cds, posters, mail outs, booklets, brochures etc...and I'm not saying to use PSP instead of Draw, but rather together. Every rastor I import into Draw is edited in PSP.

What Draw does for desktop publishing & vectors, PSP does for webtop publishing and rastors. It stores bitmaps and text vectors as objects and layers (resizable), so you can paste multiple bitmaps over the top of each other or change text and things and still reference the lower bitmaps, even after saving(as a .psp). It then allows many photo quality effects to be applied just not achievable with pure vector, perfect control over every point of color and shadow. Coreldraw and PSP complement each other nicely, I just wish CorelPaint was more like PSP.

Vectors do resize and print far sharper than rastors, but you cannot create vector buttons or banners to put on a website (or in software) that look as nice as you can do with a pure gif or jpeg, though for simple and fast banners I guess Draw is fine.

I just like the right tool for the job.

Good info nullgod, we don't deal much with webpage graphics but if we do we'll consider PSP. I have noticed that the buttons created in CorelDraw are less than desired for the web. We also have Photoshop 6.0 that I could experiment with.
