Mukul Mishra	32817633c9	Fix #7798 : Refactor scratch canvas usage. Fixes extra canvas create calls. Fixes unnecessary call of `new DOMCanvasFactory`. Fixes undefined error of DOMCanvasFactory. Fixes failures in some of the tests. Fixes expected behaviour. Remove unused vars.	8 years ago
Jonas Jenwald	bc736fdc7d	Adjust the `brace-style` ESLint rule to disallow single lines (and also enable `no-iterator`) See http://eslint.org/docs/rules/brace-style. Having the opening/closing braces on the same line can often make the code slightly more difficult to read, in particular for `if`/`else if` statements, compared to using new lines. This patch also, for consistency with `mozilla-central`, enables the [`no-iterator`](http://eslint.org/docs/rules/no-iterator) rule. Note that this rule didn't require a single code change.	8 years ago
Jonas Jenwald	c850968fa7	Remove `globals` that are now unnecessary thanks to the use of various ESLint environments (e.g. Node, ShellJS, Jasmine)	9 years ago
Jonas Jenwald	c36468cbce	Fix errors reported by the `keyword-spacing` ESLint rule http://eslint.org/docs/rules/keyword-spacing	9 years ago
Yury Delendik	0576c9c6c6	Replaces all preprocessor directives with PDFJSDev calls.	9 years ago
Jonas Jenwald	cb5f9df0c8	[EnhanceTextSelection] Make `expandTextDivs` more efficient by updating all styles at once instead of piecewise I intended to provide proper benchmarking results here, as outlined in https://github.com/mozilla/pdf.js/wiki/Benchmarking-your-changes, but after wasting a couple of hours over the weekend getting weird results I gave up. It appears that there's a lot of, i.e. way too much, variance between subsequent runs of `text` tests for the results to be meaningful. (Previously I've only benchmarked `eq` tests, so I don't know if the `text` tests has never worked well or if it's a newer problem. For reference, please see the results of back-to-back benchmark runs on the current `master` with a very simple manifest file: [link here].) Instead I used `console.time/timeEnd` in `appendText` and `expandTextDivs` to be able to compare the performance with/without the patch. The entire viewer was (skip-cache) reloaded between measurements, and the result are available here: [link here]. Given the troubles I've had with benchmarking, I've not yet computed any statistics on the results (e.g. mean, variance, confidence intervals, and so on). However, just by looking at the data I think it's safe to say that this patch first of all doesn't seem to regress the current performance. Secondly it certainly looks very likely that this patch actually improves the performance, especially for the one-glyph-per-text-div case (cf. issue 7224). Re: issue 7584.	9 years ago
Tim van der Meij	96593571eb	Optimize scale calculation in `text_layer.js` This patch avoids having to calculate the scale twice by saving it in the properties object. Moreover, we remove a temporary variable and place parentheses around a calculation inside a string concatenation.	9 years ago
Tim van der Meij	b3818d5c36	Replace `div.dataset` with a `WeakMap` in `text_layer.js` This patch improves performance by avoiding unnecessary type conversions, which also help the JIT for optimizations. Moreover, this patch fixes issues with the div expansion code where `textScale` would be undefined in a division. Because of the `dataset` usage, other comparisons evaluated to `true` while `false` would have been correct. This makes the expansion mode now work correctly for cases with, for example, each glyph in one div. The polyfill for `WeakMap` has been provided by @yurydelendik.	9 years ago
Tim van der Meij	b10add14f3	Refactor `text_layer.js` to pass the task as a parameter We pass many parameters to `appendText` while we might as well pass the `task` object that contains them. This saves a few lines of code and makes the signature of `appendText` more clear. We do the same for `expand`, which is useful for the next commit in which we replace `div.dataset` with a `WeakMap`. Furthermore, this patch adds a missing parameter to a comment block to make it clear which parameters remain.	9 years ago
Tim van der Meij	7c961b6b7a	Minor code style improvements after #7539	9 years ago
Jeremy Press	6faa84abdb	Continuing fairexpand #6663 1. Expanding divs to improve text selection. (Yury) 2. Adding enhanceTextSelection as an option. 3. Moving feature functionality from text_layer_builder.js to text_layer.js. 4. Added expandTextDivs method to only load expanded divs on first click, and only show on subsequent clicks	9 years ago
Tim van der Meij	6a7012aaca	Remove unused variables These have been found using `gulp lint` in combination with the `unused: true` parameter for JSHint. Unfortunately there are too many false positives to enable this feature, but now that most globals have been removed because of the conversion to UMD the results are much more useful than before.	9 years ago
Yury Delendik	1d12aed5ca	Move all PDFJS.xxx settings into display/global.	9 years ago
Nico Schlömer	7cb055307d	Add element to text layer even if width === 0 Some browsers render certain special characters with width 0, others with strictly positive width. (For example, the Greek Delta, Δ, has width 0 in Google Chrome, and a positive width in Firefox.) The `if` clause in operation so far results in different text layer DOM trees for different browsers. This commit fixes that by adding the elements independently of their width.	9 years ago

Yury Delendik	85e95d34ed	Use RequireJS in the viewer, examples and tests.	9 years ago
