  1. POOptimizing TIF and EPS files with PHP
    text
    copied!<p>Are there any PHP libraries out there that will reduce the size of an EPS or TIF file? Or create one with a reduced size in the first place?</p> <p>I have seen some sites that have automated TIF and EPS generation and produce significantly smaller file sizes than I can and their quality is the same (to my eye anyway).</p> <p>I have tried with ImageMagick on the Linux command line but it doesn't appear to have any specific optimize ability for these formats.</p> <p>Thanks for any help you folks can offer.</p> <p><strong>Edit:</strong></p> <p>I'm trying to optimize someone else's code and haven't used ImageMagick before so am learning it as I go. @Dagon, are you sure it doesn't have TIF support built in? I could totally be misunderstanding things but it appears to convert JPG's to TIF's as is. But you're definitely right about EPS, I see now that the code is using InkScape to create the EPS files.</p> <p>Anyway, I have found if I tell it to use the ZIP compression a TIF's file size it is reduced significantly. Example: <code>convert mypic.jpg -compress zip mypic.tif</code></p> <p>Does anyone have any idea if there are drawbacks to doing this? The program is a bar code image creator so there's not a lot of image data I'm worried about losing as the images are quite basic. They're coming out clean looking which is what matters to me.</p> <p>As for the EPS files, it appears the EPS generated by another site is done so with a different program than Inkscape. Their EPS generator is specifically made for bar codes. I don't know much about the EPS format, but it appears they make theirs significantly smaller by defining a few rules at the top since they know what they're making every time. Where as Inkscape keeps things vague since it could be used to make any kind of vector.</p> <p>So I guess I have found my answers. If anyone has anything to add or point out what I have dead wrong it's still appreciated.</p> <p>Thanks!</p>
