I am using Serenity with Selenium to automate a webpage having images (list of large thumbnails). I am checking if there is an option to search in the UI with a text/word that is displayed in the image content.
For example: I want to find if the image exists in the UI having the text.
I want to find if the image exists in screen having this word "Pexels".
Yes, it does not matter for Sikuli whether that's a printed text or a part of an image. What you have to take into account though is the enclosing region you are going to look for this text in as this might affect the result you are getting. Internally Sikuli is using Tesseract OCR which can be sensitive to text placement within a region. So if you see you are getting inconsistent results, first of all make sure what is actually being detected within the selected region and then try to change it to focus on the specific area of the test if possible.
I need to manipulate the content streams of a page in such a way that if the contents of Tf of one of the elements of TF matches specific values the background area of those squares/glyphs needs to change.
I think that I would need save the graphics state, after creating two different string objects, then apply a fill operator then restore the graphics state.
My question is: would the fill operator recognize the area of the matched string and fill just this?
Second: would I need to repeat this sequence for each element of the TF array?
It's not quite that simple.
You have to determine the position of the text yourself (by keeping track of the current transformation matrix for the whole page content stream and the text matrix for the text object in which your text in question is drawn) and then insert a path outlining that area and filling it just before the text object in question.
But this in particular means that it is not necessary to split the strings of the text drawing instructions to have the search text be drawn by itself.
By the way, if this change of background is meant to represent something like a text marker marking, an alternative to changing the page content would be to create text markup annotations for the determined coordinates. That way you would merely have to parse the page content stream for the coordinates, you don't have to change it. In particular if the text drawing instructions may also be in some form Xobject referenced from the page content instead of the page content itself, this may simplify the code.
I have to embed an image in Birt. But I don't want the image to be displayed in the report itself. I want the image to be Embedded in the PDF that I will be able to export only. I tried searching for a way to do this, but was unsuccessful.
Thanks in Advance
To add an image to your report that will only be displayed when exported to PDF:
Add the image to the desired location in the report.
Select the image in the Layout view, then select the Visibility options in the Properties tab of the Property Editor:
Check the Hide Element checkbox;
Select the For specific outputs... option;
Check the specific output checkboxes for all formats except PDF
If you now save and run the amended report, you should find that the image is only displayed when exported to PDF.
I am using ABCPDF.net to generate my PDFs from HTML files. There are 3 images on the HTML page which; of which 2 images are generated but the third is one is not on the PDF. I have tried to move the logo around but without any luck. This is my first time using this product which I am impressed with but this one problem is throwing me off.
From memory there could be one or two things causing this.
1) If your image happens to cross over the boundary of the page even by 1 pixel it will not be rendered.
2) You have to make sure that all of your elements are loaded in a procedural fashion by which I mean that whatever you want to be displayed on the top must be added to the page last. If you don't do this you may find that a rectangle you declared to contain some text for example will be displayed over the top of your image which will obscure it.
3) Sounds daft but just double check all syntax and the images location and ensure that you have referenced it correctly.
If all else fails could you provide some source code or a more in depth explanation.
EDIT: Also double check that you have set the correct size on the image when importing it as you may find it reverts back to the actual dimensions that it is on the disk which could make it too big for the page thus not rendering it.
I want to adjust the size of the "Browse" section seen in the file upload button in HTML. When I try to adjust the size using "size" or "width" attributes, only the whole size is reduced. But I want only the size of the "Browse" button part to be reduced and not the textbox part which displays file path. Can I do this without using CSS? If yes , how?
The file input element is notoriously difficult to style. One of the problems is that it's really a single element, even though it renders as two elements.
One approach is to obscure the entire element behind the scenes and present the user with custom elements instead. Here's an article about it. Basically the file input element is hidden and some custom elements backed by some JavaScript are handling the UI and passing the necessary information to the file input.
It is very difficult to change the appearance of the Browse button as it is typically hardwired into the browser.
However, at Quirksmode.org|Styling an input type="file", there is a long post that discusses complex CSS techniques for changing the appearance of file input elements.
