Default Jaggy edges on imported bitmaps

Hello,

I have searched the forum but could not find this topic. Can anyone help with
something that is probably a fundamental and easy fix but I am just not getting!

I am using Flash CS3 and am making a slideshow. I need to import a logo that
has no background in its original format (psd at 600dpi) but of course when I
save it as a jpg or png it puts a white background in. As a gif using
transparency, it comes out really nasty and jagged. To preempt this, I have put
a black background on the actual logo as the slideshow I am doing has an all
black background. Now when I try either importing it as a gif or jpg, it still
looks jagged. I have tried rasterizing the file before saving it to web but
still looks the same. I have tried using matte black when saving as a gif and
taking out the transparency function. Still awful.

I am starting with a super nice clean 600dpi logo, so I feel I have no excuse.
What am I doing wrong? Thanks!

Incidentally, I meant to ask, at what dpi should a bmp be imported at. I would have thought 72dpi, but maybe I'm wrong?

Since this afternoon, I have been trying to rebuild the logo in Illustrator (a
program I'm not very familiar with) and had luck exporting it as a swf and
importing that into the flash file. However, the one part of the logo that I
did not build in Illustrator and was imported from Photoshop will not show up
when I publish my flash file. Is there something special I should do with the
imported bitmap part?

Thanks for any help!

Screen images are 72dpi, and you should use that. PNG works best for
transparency as it has a full 8bit alpha channel - ie 256 levels of gray as
opposed to a 1bit alpha using GIF. JPEG has no transparency. So, first
change to 72dpi and size the image accordingly, save as PNG with
transparency. It will then import at 1:1 and have antialiased alpha info.

Try to create your image on 72 dpi and import it as PNG-24 transparent instead
of PSD. And After Importing open the properties of the image from the library
and choose allow smooth, this will prevent having a jogged edges.

Thanks to both of you. I will try these methods. In the meantime, I ended up
rebuilding the logo (text) in Illustrator and had to import the eye image from
my photoshop file, first putting a black background on it. I exported the whole
thing several different ways, but the only thing that worked was exporting it
to a swf file and importing it into Flash CS3. However, in order for the eye
image to show up, I had to click on the eye image and select rasterize. (I feel
like I'm flaying around in the dark on this one!) The eye showed up, but is
still a tiny bit jaggy, but acceptable. But now, I've noticed I have a slightly
less dark black background on the imported Illustrator file (as a swf) than the
rest of the screensaver which has a black background too. Is this because
Illustrator uses CMYK instead of RGB? Can I convert the black in the
Illustrator file to RGB so it might match better?

Thanks again...

I tried both these methods but the image still had jagged edges. I must be
doing something wrong along the way. This is what I did:

I started with my 600 dpi photoshop file logo that has text and an eye image.
It has a transparent background. I sized it down a bit, then saved for web as a
png-24 with transparency. Then, I imported it into my Flash file library and
placed it into my flash file. When I published, it was still jagged. Do you
have any ideas what I did wrong? I tried both checking and unchecking the
interlace box. I would really appreciate any help on this.

I'm still getting the best result with the imported Illustrator file but the
background is not matching completely probably due to CMYK v. RGB in the flash
file.

Thanks very much.

Horgy

I would recommend importing in your "eye" graphic and text seperately if
possible and combine them in flash. Set your text in Illustrator, convert to
outline, then copy and paste it into flash. Your graphic should be brought into
Flash as a 24 bit PNG. Create a new movie clip and combine the two elements.
And yes RGB and CMYK are different. Always work in RGB when creating graphics
for Flash projects.
Also if your a scaling the completed logo in Flash. Try putting this
Actionscript in the first frame of your movie --
_quality = "best"
The vector text you copied in from Illustrator will resize OK on its own but
the PNG may not, this script will help.
Cheers.

Horgy,
Try using "Save for Web and Devices, instead of "Save As"....great option that
lets you preview and has robust options at a glance!!

Peace,
Laggy

P.S. Test never ports over properly for me either :-(
