I'm using AI902 on Win2000. I'm placing Tiff images via FILE/PLACE and they are coming in at 100%. But when I go to Links palette and look at that image's info. it says there is a 24% Transformation to Horiz and Vert. But there has been no such transformation. Very confusing for an Architects' firm dealing constantly with accurate scaling.

If I place JPEGs or PSD images they come in at 100% and show no Transformation.

I've tried recreating Prefs. but no joy.

Please help.

Agreen,

When you manually resize a raster image using the bounding box (SHIFT to maintain aspect)it does NOT record as Transformed in the Object, Transform, Scale menu. But using the Transform palette it will show it. This, bye the way isn't just a function of TIFF format, it also occurs with JPG, PSD on my Illustrator 10. But if I just Place (with or without LINK) a raster image, then manually downsize the image, Transform menu still shows 100%. But if I use Transform menu to scale to 50% then close and later go to Transform menu with this image selected, it's going to show 50%. The Transform % in Transform menu will only show when it's done in Transform menu. Links, Information palette will show TRUE % of transform from original. In this case, it shows both the manual and the Transform Scale menu % of change.

Bob,

Thanks for the input, but it sounds like the explanation for this comes from somewhere else. Here's what Adobe Tech Support said:

"This is luckily not an issue, but just a misunderstanding of the word
"scale" in that link information dialog box. It is rather a subsampling
factor of how a 300dpi tiff image is displayed on a 72dpi monitor - i.e.
only 24% of information can be seen at that resolution. If you were to zoom
in, more detail would become available, i.e. the information is all there,
but you see it as 24% on the monitor. It is not related to the size of the
image: if you use the ruler you can measure the file and see that it is
still 5cm by 5cm, just as it is in Photoshop. The 72dpi ducky (sample
file)would display at 100%, the 300dpi sample file from yourself as 24% (300
divided by 72 makes 4.17, times 24 makes 100.008), a 400dpi tiff would
display as 18% scale factor and so on. You cannot reproduce this with eps
files because the file format is different. Tiff is based on pixels, eps
files can hold vector information as well, therefore you don't get the same
scale factor as with tiff files"

It took them 3 days to respond, and in my opinion is a bad thing about the software. I want to know what scale the image is NOW in relation to when it was BROUGHT IN. Anyway, I suppose I'll just have to check back with the original files.

Ashley.

Ashley,

That's the information that's contained in Links Palette, options, Information. That's always going to give you current scale ratio to the original as you Placed it into Illustrator. And that scale is maintained once the file is saved as well.

go to http://www.gzg2002.com to download Clever Ruler, it will help
you. It is a very special ruler that can transparent and rotate any
degrees.
