![]() Here's the same image after some tinkering....50k file size instead of 298k and it looks better to me. http://www.sparkbench.com/CBtext1revised.gif Bill, I used it, looks great, thanks a bunch. I've also added some more stuff, check it out. http://radioheaven.homestead.com/CloughBrengle.html Ron |

![]() Here's the same image after some tinkering....50k file size instead of 298k and it looks better to me. http://www.sparkbench.com/CBtext1revised.gif Bill, explain to me what you did to get it so small. I'm sure I'll need to do again for some future page. I have some Clough-Brengle catalog pages that I'd like to put on, but the scans are more than 2 meg. and still are hard to read the small text. Thanks, Ron http://radioheaven.homestead.com/CloughBrengle.html |

Thanks, Ron I resized it to 500 pixels wide - it was 1083 wide so that alone reduced the file size to about 25% of original. No point in having a 1083 pixel wide image that has to scrunch into the box provided on the page. That causes it to compress and may look 'funny' depending on a guys browser, video card, monitor, etc. At 500 pixels maybe it still compresses (or expands) a little bit. I can't tell from the script what the size of the rectangle is supposed to be but on my browser it appears to be about 500 wide. Next I took it down from 8-bit/256 colors to 4-bit/16 colors. As mentioned before, thats a no brainer for a black and white image. That reduces the file size even further. Then just for looks I changed some of the 'almost' white or 'almost' black pixels to true black and white leaving the greys in the middle of the range. For your 2 MB scans try something along the same lines. If they are 2MB it sounds as if they were scanned as color??. Get them into black and white for starters and gradually step down to 256 and then to 16 color black and white and see how they look. Old yellowed pages are sometime difficult to handle but there's ways. After you get it looking good, resize it down to whatever width is appropriate for the page. If there's a lot of fine print you might not be able to get it as small as you'd like. The alternative here is to put a reduced size clickable link on the main page that can carry an interested surfer to a full size version. That way the main info page doesn't get bogged down. Crop the edges appropriately. You can often knock off a bunch of the file size just with simple cropping. And if its a fine text page, don't try to put it in a box like the letter on the home page because thats gonna really scrunch down the fine print. Hope this helps, drop me an email if you'd like to discuss it further. -Bill exray at coqui dot net |

![]() Hope this helps, drop me an email if you'd like to discuss it further. -Bill, I scanned a Clough-Brengle model 110 catalog page, it was in grayscale 300 dpi. The original scan was over 3 meg. I used Photoshop7 to reduce the from more than 5K pixels wide to just 1000 wide. The file size was reduced to about 125K and still looks great on the web page. I may try going even smaller. Thanks again.

Then just for looks I changed some of the 'almost' white or 'almost' black pixels to true black and white leaving the greys in the middle of the range. If you had taken it all the way to 2 colors (B & W) the GIF compression would really have been something. FWIW, the enlarged schematic of the 4581 TX compressed instantly to 12K, though still 841x411. Although the original was a full-color JPG, there were apparently only black and white pixels in it. When converting to GIF, GIF has to figure out ahead of time how many unique colors re in the image, and it quickly found there were only two, so it went to B&W GIF, which is very efficient. --MikeK.

Thats why I went after the 16 grey colors one at a time. Couldn't pull it off. -BM |

If you reduce it to 2 colors, the lines and letters break up around the edges. Using 16 shades of gray permits "aliasing" to fill in the breaks so the eye sees it as smooth. You were right to stop at 16. I just wanted to point out that the typewritten sheet in the home page really is already 2 colors (B&W), having been expertly scanned and worked over by someone. Likewise the large schamtic for the TX. Both these should make good 2-color GIF. Er, I'm not really certain aobut the opening sheet -- but I did save and check out the TX schematic, so know it's 2 color already, and compresses almost 10:1 under GIF. --Mike K.
