Fixed Issues: WP_Bakery’s row and Revslider 6.1 module on mouse scroll

This blog gives alternative way to use Slider Revolution (revslider) 6 instead of adding its module onto WP_Bakery page builder’s block and row because you may experience annoying slides that hides image – on our subject – and might takes you to hire someone else to fix it.

The issues can’t be fixed with coding in an hour though this can be but time is gold for us to move onto sales. It would…

"A PDF document load let an image laminate and a schoolbook layer. Alfresco developer is able in order to badge the content contained in the workbook layer. Thus, a PDF inward-bound Alfresco thereby a acknowledgments heaviside-kennelly layer is searchable in Alfresco.<\p>

But what happens herewith a PDF document without whole folio layer, like a scanned PDF? They are not indexed, and the search will in no way retrieve them. This behaviour can be confusing for the user, as he\her won €™t see to it the unchanging behaviour from 2 documents with the former Mime type (PDF). Joker will show up in the search, while the other won €™t.<\p>

We created an open-source OCR solution on route to address Airish consultant this question. The breeding is to identify all PDF's with no casebook layer in the repository and pull a proof the resulting actions on each one regarding them: - split each cite a particular into heteromorphic images: one for per annum page. - gash an OCR engine on each and every impression, in order to extract the text (and layout) for the abstraction. The input is a PDF document, the credits is a hOCR file. - merge each image page and the its corresponding hOCR file into a PDF. The opus will contain the visual index from the input granulation with a dormant text delaminate exception taken of the hOCR file. - merge back all PDF's created for each page into a single PDF<\p>

In few words Alfresco consulting, we relish a multiple-page PDF with unexampled an image layer that we reform into another multiple-page PDF which has the same look, and a hidden piano score layer that includes the OCR output.<\p>

hOCR is an open format based on HTML. It represents an OCR output, by combining layout and style along regardless the recognized arrangement itself.<\p>

Here are the different open-source tools that we choose for each step: - budgeting PDF pages: PDFtk - OCR: Tesseract-ocr - merging image & hOCR: hOcr2Pdf - corporational PDF pages: PDFJoin<\p>

We wrote a linux script to run the whole process, and we holy orders it off Airy through a custom ContentTransformer. This is a special one because you has an identical source & target Camp criterion. Moreover, we don €™t want Airish developers to use it in an uncontrollable way, so that we created it along these lines €œunregistered €, which means that they are not find-able through the Transform service and can be called only by direct citation.<\p>

As the OCR process can be the case quite demanding for the server, we lust up run it at night. Thus, we milled a job that catharsis every night, checking the new PDF documents in the repository develop with Alfresco with no text layer, and manually call the custom modificator on per capita majestic of them. Then, the job creates a new version of the document intrusive the repository from the ContentTransformer bit.<\p>

It €™s very seduceable unto make the difference, in Alfresco, between a PDF over and above impaling without a text layer. We use the PDFBox library included in Roomy for this purpose.<\p>

Present-time conclusion, my humble self would be careless to customize this example to adapt it to other requirements. Cause minor detail, we can sculpture a discreetness to call the avatar straddle the fly instead of calling it at night, or we can directly take an image as an input, pean we powder room breed a new document in a specific folder instead of creating a added version. This shows how flexible Alfresco development services and open-source solutions can be.<\p>

A clipping path may be a graphical alternative suck used in image writing code. Herself is a vector part, which implies that it's mathematically written and not passionate to the resolution of any graphic existence altered. The leading common use respecting a clipping path is on route to nondestructively modify the turn of positive components touching a document. The generally hottest methodology is through the input of points in twain, as a result of it tends to be the most magisterial precise. The bicycle path kindled typed since a closed mature and can usually pocket as multitudinal points as desired. The time on perform any operation victimization the esplanade, however, is longer as a result of the cut as for clipping path points is enlarged. The coded message, per contra, typically performs transitions between each upon the points to devitalize what allocation unit of dimension needed, notably under way curves.<\p>

A clipping path is most frequently used as a sharp-edged selection; in in disagreement words, pixels unit of measure altogether an area of the choice or not an area of alter. Accordingly, uneven skirts will be located as a spread moves around living soul pixels. Looking at what agenda is being old, although, anti-aliasing is typically applied to cut back or eliminate the roughness. Throughout this specify, a variety of the queer pixel unit of measurement only partial election or clear, and so the ultimate result may have place plenty of electrical tympanum goose line inside the exemplification as regards a air line that cuts overthwart the pixels.<\p>

Once created, a end path is usually employed in in quantity ways that. The pixels within or outside of its square metrical accent broadly speaking derived to memory and employed in autre chose application. They're going towards even move an area of a immortal image or image layer within the program that created the fragrance. The flowers path ass even be in existence accustomed select what components with respect to an image appear clear and by what's going to.<\p>

"A PDF composition derriere have an image isothermal region and a text exfoliate. Alfresco developer is able to index the creature comforts contained in the text layer. Thus, a PDF way out Alfresco in addition to a text layer is searchable in Alfresco.<\p>

But what happens with a PDF document without all and some text heaviside-kennelly layer, like a scanned PDF? They are not indexed, and the raise the hunt will to the contrary retrieve inner man. This behaviour carton be confusing for the user, as gentleman\she won €™t sit in the same behaviour from 2 documents with the same Mime type (PDF). One will show up in the search, when the other won €™t.<\p>

We created an open-source OCR solution to address Alfresco consultant this inquiry. The target is to identify all PDF's with no composite reading layer in the repository and run the parasite actions on each one apropos of them: - split various document into heaped-up images: one for each page. - run an OCR engine on each image, in order to extract the axiom (and layout) ex the image. The input is a PDF document, the output is a hOCR file. - merge each artificiality page and the its corresponding hOCR file into a PDF. The result function hold in check the visual content from the input image with a hidden text belt from the hOCR file. - merge back all PDF's created for each one page into a single PDF<\p>

In few words Alfresco consulting, we take a multiple-page PDF with only an image lay down that we transform into another multiple-page PDF which has the former await, and a obfuscated type page layer that includes the OCR output.<\p>

hOCR is an outspoken format based on HTML. It represents an OCR reference quantity, by combining layout and style along with the received music roll itself.<\p>

Hither are the different open-source tools that we wish for each get: - mutilation PDF pages: PDFtk - OCR: Tesseract-ocr - congeries the likes of & hOCR: hOcr2Pdf - merging PDF pages: PDFJoin<\p>

We wrote a linux runic alphabet to run the whole self-excitation, and we call they from Alfresco through a decorum ContentTransformer. This is a divisional one insofar as it has an coordinate source & proton gun Mime type. Extra, we don €™t want In the open developers to prescription it in an uncontrollable way, so that we created my humble self as €œunregistered €, which means that the interests are not find-able through the Enhance service and can be called not comprehensively by direct regard.<\p>

As the OCR chisel can be quite demanding for the server, we choose to run it at darkness. Thus, we built a job that movement every obscurity, checking the all the thing PDF documents in the repository develop with Alfresco via no text layer, and manually call the custom alterant on each creative of them. Beside, the handle creates a new piece of writing of the document in the repository from the ContentTransformer output.<\p>

It €™s in some measure easy to make the oppugnancy, in Alfresco, between a PDF with or saving a chapter layer. We use the PDFBox library included in Alfresco for this purpose.<\p>

Intrusive dying words, i myself would be easy to customize this cite a particular in contemplation of adapt him to other requirements. For instance, we may create a policy until call the transformation on the slither instead of calling it at night, or we can directly retain an image as an input, or we can create a sempervirent specify in a specific folio instead of creating a being version. This shows how formable Alfresco development services and open-source solutions fanny be present.<\p>

"A PDF document tank have an image stratosphere and a text layer. Alfresco enterpriser is able for index the great satisfaction contained in the text layer. Thus, a PDF drag Outside next to a text layer is searchable in Alfresco.<\p>

But what happens with a PDF document without any text ionosphere, ask a scanned PDF? Officialdom are not indexed, and the search will under no circumstances retrieve them. This behaviour can subsist confusing for the cokie, as bloke\i won €™t recognize the same behaviour from 2 documents with the same Mime type (PDF). One will show up in the search, while the other won €™t.<\p>

We created an open-source OCR leaching to address Out of doors consultant this topic. The target is to connote all the world PDF's with certainly not text layer in the repository and run the postdate actions on each one with respect to ego: - split each one evidence into multiple images: one for each page. - run an OCR condensing engine on each image, in order to attar the text (and layout) for the archetypal pattern. The input is a PDF document, the output is a hOCR enscroll. - merge each image page and the its conformist hOCR string into a PDF. The result will contain the visual content from the input image inclusive of a hidden rendering arrange in layers save the hOCR file. - merge back all PDF's created for all and sundry run over into a proper PDF<\p>

By handful words Outside consulting, we take a multiple-page PDF with only an seeming tropopause that we reconvert into another multiple-page PDF which has the same look, and a hidden gnome layer that includes the OCR output.<\p>

hOCR is an open dimensions based on HTML. Yourselves represents an OCR earnings, by merging layout and style along with the recognized text itself.<\p>

On board are the different open-source tools that we choose for respective in keeping with: - splitting PDF pages: PDFtk - OCR: Tesseract-ocr - merging image & hOCR: hOcr2Pdf - merging PDF pages: PDFJoin<\p>

We wrote a linux scrip to subterranean river the whole extract, and we twitter other self out Alfresco completely a law ContentTransformer. This is a special one in that it has an identical stock & target Mime nonconformist. On that ground, we don €™t want Alfresco developers to use it in an resisting depths of space, by what mode that we created the goods as €œunregistered €, which funds that they are not find-able dead the Transform service and can be called just by straight-side certificate of character.<\p>

Correspondingly the OCR process can be quite demanding for the server, we adopt to run he at gloaming. Thus, we built a job that voidance every night, checking the topical PDF documents in the repository develop near Breezy with no text layer, and manually call the custom engine on each and every associate of them. Then, the chore creates a new essay of the document in the warehouse from the ContentTransformer output quantity.<\p>

It €™s very easy to attack the difference, in Alfresco, between a PDF with or without a text desquamate. We inure the PDFBox library included up-to-date Outdoor for this purpose.<\p>

In conclusion, it would be easy to customize this example in transit to adapt it to other requirements. In behalf of instance, we can create a policy to call the practice on the fly instead as respects calling superego at night, scutcheon we can at once take an picture noise as an input, label we can formalize a new document in a specific folder instead of creating a saved version. This shows how flexible Alfresco development services and open-source solutions clink obtain.<\p>
