I have some psd files that I need to add in my epub for ipads. Is there a way to do it? Does epub support '.psd' files? If so, what will be the media-type that has to be added in the 'package.opf'?
The reason I need to add the psd files is that I need images with no background frame or with a transparent frame. I think its not possible to get a transparent frame in jpeg files and tiff files. Please advice.
Thanks in advance

No, PSD files are not supported. JPG, PNG, GIF, or SVG. That's it.

I converted some SVG images into PDF and png files for my iOS app. When adding them to the UIImageView, the pdf images look smaller than the png equivalent. The scale type was set to center, so no scaling happens at runtime.
btw, the pdf and png look the same when I open them in preview and adobe reader
Anyone had same issue and got a solution for that?
When converting an SVG to PDF, make sure the DPI is set to 72. That way, the size will match with the PNG resource that you have. Xcode actually expects vector-based resources to be 1x in size.
I'm wanted to do something like web page that only allowed user to view only jpeg, png and gif file types from ImagePickerController. The reason I want to do this is because my server only accept those file types.
Anyone know how to do it? Or any better solution for it?
I need to edit a png image,by giving it border and drop shadow effect. But the final size of the edited image is too high to use for a mobile app .I know that size of jpeg is less compared to that of png.So i convert that image to jpeg and tried to give drop shadow and border effect.But that image is not having transparent background..Is their any other methods to accomplish this using jpeg?
Another option is to try either ImageOptim for losseless compression, or its lossy cousin, ImageAlpha.
ImageOptim tries a series of lossless algorithms to shrink a PNG and selects the smallest result of the bunch. It has taken 25% to 50%+ of quite a few of our images.
ImageAlpha, on the other hand, is lossy and can further crunch the image, with results more like JPEG but without losing Alpha.
You would also do well to disable PNG compression in Xcode as shown here, with additional details here.
What #minitech wanted to say is not about scaling, it's about file compression. jpg and png files usually have some data that could be removed from the file. There are some compression methods to reduce file size (note that is size in kbs, not in scale measurement). Jpg images can reduce file size by reducing image quality, too.
If you want another file type that accepts transparency, there are the gif format, which gives you a smaller file, but have some drawbacks, like a lack of alpha channel (variable transparency). Check this link for more details: http://www.w3.org/QA/Tips/png-gif
There are a couple of online file compressors. If you want to compress png files, you could try using http://tinypng.org/
No, jpeg image wont support transparency.But you can change the white background coming along with jpeg image
I am trying to merge a splash screen image which is in jpg format with an ajaxloader which is in gif format.
I tried the following command using ImageMagik:
convert -delay 50 splashimage.jpg ajaxloader.gif final.gif
This command does merge the gif file with the jpg image but the loader appear at the top-left corner.
I was wondering if there is an option available to place it at a specfic (x,y) point on the jpg image?
If anybody has had done a similar thing or has an idea as to how a similar thing can be achieved, please guide me through.
Thanks.
Why would you want to do this? You'd be turning a nice 24bit JPG into a crappy quality single frame on an 8bit gif. You could just use some CSS tricks to overlay the loader .gif on top of the .jpg on a webpage, which would not sacrifice any image quality to achieve the same effect.
I solved the problem by designing individual frames of images with the desired location of my text and merged them using Imagemagik.
I want to convert uploaded images that are not jpegs or pngs to to be jpegs or pngs using paperclip. Problem is i dont want to convert jpegs to pngs or pngs to jpegs, just leave them as the file type they are.
Is this possible ? If so how do i create the styles all in jpeg or png ?
Also what is the best file type to save as? I cant convert some pngs to jpgs as if they had transparency in that gets lost / changed. Also if i change all to png is not bigger and alos i am using Prawn pdf outputting these images so cant use gif.
Any pointers anyone ?
Thanks alot

In order to do this you will need to create a custom Paperclip::Processor. You can probably subclass the Paperclip::Thumbnail in doing so.
