We have an Adobe AIR application. It has an image preview feature to show TIF and JPG images inside a TitleWindow.
My requirement is as follows:
i want to highlight(yellow color) a line containing a searched term results inside that image.
i found out examples which can highlight text inside a textarea. But wanted the same thing inside image.
There can be multiple lines having this keyword. All those llines have to be highlighted.
Not sure if this is possible. Please let me know how can this be done in Flex/AIR.
Create mx.controls.Text, assign style which will paint it yellow and place over the Image. This can be done, for example, with Canvas container which allows absolute positioning.
mx:Text has no background, so it will just text over image. Or do you need some background as well?

I am using Lazarus.
I have put 2 images on a form and synchronized their positions and sizes.
I can textout to both images, and after I made the ontop image transparent I can see the combined content of both images.
I can add further text to the bottom image and see it, but I can't see text I try to add to the transparent image.
I used the following code to make the top image transparent
image2.picture.Bitmap.TransparentColor:=clWhite;
image2.transparent:=true;
I guess I need to play with the image bitmap, but I can't find a solution that is not using other software.
Can someone help me with this please?
I'm building a set of slides with bullets. I want to use "appearance" animations so I can step through the bullets with the space bar. On several slides, I have a screenshot image that I've positioned right after the bullet I want the image to be associated with. However, when I add appearance animations, the slide just displays all the screenshot images immediately, before any of the bullets appear. It seems like PowerPoint treats the images as "floating", and not associated with the bullets.
What can I do here?
The fact that the screenshot image is near the bullet doesn't make it part of the bullet or associated text, so it's behaving as expected.
Instead, try using a custom picture bullet for the text or using individual lines of text, each grouped with the screenshot image and each animated individually.
I´ve a cropped picture in a powerpoint layer and I want to change the picture without changing the size of the cropping area.
If I change the image by clicking "change picture" the cropping area resizes too, to show the whole picture.
How can I do that without changing the cropping area?
In Apple Keynote you only have to drag the picture you want to the cropping area and you only have to align it.
From my experience, I'm afraid you have to set the crop manually by "Format Picture" -"Crop" to remain the same cropping area when you replace a picture.
This isn't much help, but Libreoffice will do this. Crop, resize, then select your image and re-insert a new image - formatting will be the same, perfect for when you want to quickly redo formatting for same sized images.
In my experience, a picture that you insert to replace an existing one, using Change Picture, will "inherit" the crop&size settings of the old picture IF the old&new images are actually of the same size (in pixels) - if not, the new one will revert to the default crop&size so you will have to redo these manually.
This changes if the image to-be-replaced has any crop setting applied to it in Powerpoint. In this case, the replacing image will not inherit those, and might also be inserted with a different size&position, leading most likely to an unwanted result & further work needed.
A workaround I found is to first remove the crop setting from the old picture, replace with new image, then reapply the crop. This is still less work than having to manually redo the size&position (or to define these based on numbers copied from the PropertiesPane of the old image).
Quick work around: if you plan to have multiple same size images and you wish to use change image to swap the content on each page (something we do with floor plans all the time); don't bother cropping them.
Put the whole image in and crop it by sticking shapes on top of it, which are the same color as the presentation background color, like a mask.
optionally crop the images only when the whole presentation is finished.
There is requirement where parsys should be added on top of an image. It is like a background image with the provision of parsys so that other components can be dragged and dropped on top of it. I am using html5smartimage for image component. But, no clue yet on how I can get the parsys on top of the image. Please help if you find any ideas. Thanks.
is the image authorable? If so, how do you intend to provide click-area for the authors to change the image vs edit items in the parsys.
If the image isn't authorable, just target the CSS for your parsys and set the image.
If the image is authorable, in edit mode you want the image to be distinct from the parsys and have separate clickable areas. Then in preview/disabled modes you would generate the actually desired markup & CSS to position the parsys content over the background image.
I want to export certain shapes in powerpoint as images. For that I am using the following code:
ActivePresentation.Slides(1).Shapes(3).Export "C:\dink_template\created_files\testimg.jpg", ppShapeFormatJPG
I also tried with other image formats:
ActivePresentation.Slides(1).Shapes(3).Export "C:\dink_template\created_files\testimg.png", ppShapeFormatPNG
and I get this image:
Here you cannot notice because the white peace that appears in the image button (and also a bit in the top) is mixing with the page but if you make inspect element on the photo you will see it.
As you can see in this other image in powerpoint the shape fix perfectly and it is not bigger that the image:
Why is appearing this white peace in the top and in the button? How can I export the image without them?
EDIT
I know when it is happening. Because I try with other ones and sometimes they where not appearing and sometime it was. The problem is that when the text you write in the shape is so close to the border and you export it as image it export with this white space. Now the question is... how can I solve this?
One option would be to adjust the size of your shape and/or the size of the text accordingly to the total text length, before exporting it as an image, in order to make sure that your text will never be too close to the border...
Something else: have you checked the margins properties of your shape? Putting them to 0 might help a bit.
