Bookmark our social media video specs and ad guide!.Easily reference this social media image sizes list in our always up-to-date Google Doc.And along with our resizing tool, we’ve provided all the specific dimensions and a few quick tips to help you decide which image best fits each position.īefore we get into it, here are some additional resources: Sprout Social’s very own tool is free to use to resize, crop and scale social media image sizes. It’s hard to cut and paste an image and reuse it across all of your social networks unless you have a tool like Landscape. In this quick-scroll world of social media, the visual face of your brand is often times the first thing your audience sees and possibly the one thing they remember. What has become so important is effectively conveying your brand on social media through images and video. Image files are as test1.jpg and test2.jpg to keep this code example simple.Whether it’s a brand promotion, video, news update or even a meme, visual content rules the social media landscape.In attached screen shots of PDFs, grey color is just a background of a PDF viewer.Image.scaleToFit(pdfA4usableWidth, pdfA4usableHeight) Ĭlick here to see code sample with console output ("A4 usable width: "+pdfA4usableWidth+", usable height: "+pdfA4usableHeight) Multiple images to PDF on separate page at top with margins float leftMargin = document.getLeftMargin(), rightMargin = document.getRightMargin() įloat topMargin = document.getTopMargin(), bottomMargin = document.getBottomMargin() įloat pdfA4usableWidth = PageSize.A4.getWidth() - leftMargin - rightMargin įloat pdfA4usableHeight = PageSize.A4.getHeight() - topMargin - bottomMargin tFixedPosition(i + 1, 0, PageSize.A4.getHeight()-image.getImageScaledHeight()) Ĭlick here to see code sample with console output Solution #2. Multiple images to PDF on separate page at top without margins image.scaleToFit(pdfA4usableWidth, pdfA4usableHeight) Following are code sample of solution for both scenarios. Now, if you want to have margins in your pdf then you will have to change code for scaling an image and setting fixed position accordingly. In order to enable scaling of images to fit on page and also position them at desired location on page you need toįirst scale an image using method image.scaleToFit(fitWidth, fitHeight) and then calculate bottom position using scaledĬalculate bottom position using scaled image height ( image.getImageScaledHeight()) and page height. Auto scaling will happen but not until after image has been added to document but to set position of an image at top of the page we need image's scaled height in calling following method tFixedPosition(i + 1, 0, PageSize.A4.getHeight()-image.getImageScaledHeight()) So it turns out that getImageScaledHeight() method doesn't work if auto scaling is turned on using setAutoScale(true). I wanted others who might run into similar issue to benefit from my solution hence I am posting it as an answer instead of commenting on my question. Solution to add multiple images to PDF at top of each page with scaling. PDF #1-Without auto scale flag #2 Auto scale set true on image I would really appreciate if anyone can provide best way to or a workaround to achieve this. But looks like when you set margin, page number doesn't have any effect and all images get added one after another on first page. I tried another approach by setting pageNumber(i+1) and setMarginTop(0). This method returns height of image in pixels and not in user units therefore it still leaves some margin on top. Therefore I first tried to calculate bottom position but subtracting height of image using getImageScaledHeight(). Image image = new Image(imageData).setAutoScale(true) īut in example given at above link adds image at bottom left corner of each page. I started with iText 7 example available at following link to generate multiple pages. if there are 5 images, resulting pdf will have 5 pages (A4 size), each containing one image at top of the page. My requirement is to generate a PDF document with multiple images, each positioned at top left corner of individual page (after default margin of 36 units). ![]() There are multiple question like this which have been answered but those requirements are not exactly like mine therefore please read read all requirement before marking it as duplicate. I have searched multiple similar posts and tried various configuration to achieve this so but couldn't get it working with latest iText 7 libraries.
