Bad image quality in chm - RH10

Hi,

I've been capturing screenshots and saving them as .png for both PDF and chm output. Images in PDF look good,  but the quality in chm looks really bad, most are blurry and you can't even see the texts inside the images. Any suggestions on how to improve the images in chm?

Thanks in advance.

    Hi,

    Personally, I would recommend using gifs. Make sure you create your gifs from a good a starting point as possible. What we do here is capture using paintshop pro at high quality, then save as gif. We've found this works well in web, pdf, chm and web help formats..

    Hi there

    Sounds like you are possibly inserting the images then scaling them down to fit specific dimensions? If so, that's your issue. The browser does an awful job of scaling. You will be much better off by doing a couple of things.

    1. Do as much as you can to properly size the image as small as you can before you even capture.

    2. Use a dedicated image manipulation application to rescale the image and save it at the smaller size.

    SnagIt

    Paint Shop Pro

    PhotoShop

    Etc.

    Cheers... Rick

    Thanks, Rick. That really helps but when I scale the image, now it looks good on chm, but the quality on PDF is not that good anymore

    Hi there

    Sounds like you need to use two versions of the images. Then apply Conditional Build Tags to them. One for Print and One for online. Actually, those are the exact two tags RoboHelp creates for you by default.

    Then when you create a PDF, you exclude the images tagged with Online. When you create the online, exclude the images tagged with Print.

    Cheers... Rick
