I am using PHP libvips library when I am using this function writeToBuffer for write to buffer the image it gives me below types of error.
Fatal error: Uncaught Jcupitt\Vips\Exception: magicksave_buffer: libMagick error: no decode delegate for this image format `' # error/blob.c/ImagesToBlob/2413
Note - This error occurs only when my image type is gif
$imagePathInfo = pathinfo($inputFileName);
$imgExtension = $imagePathInfo['extension'];
$img = Vips\Image::newFromFile($inputFileName, ['access' => 'sequential']);
$img = $img->writeToBuffer('.' . $imgExtension);
By default libvips will only load the first frame of an animation. To load all frames, set the n parameter (number of pages) to -1. Use:
$img = Vips\Image::newFromFile($inputFileName, [
'access' => 'sequential',
'n' => -1
]);
libvips 8.11 uses imagemagick to write GIF images. You need to tell imagemagick what format to write in with the format parameter, eg.:
$img = $img->writeToBuffer('.' . $imgExtension, [
'format' => $imgExtension
]);
libvips 8.12 (due by the end of Nov 2021) will automatically pass the correct format value to imagemagick, and also has a dedicated and much faster GIF writer.
I am using Amazon Textract to extract data from a scanned document. Now I want to convert the output to a PDF file. Below is a sample output of Textract:

As you can see, the output contains text, height, width and its XY coordinates. How can I place the text with same co-ordinates into a PDF file?
Assuming you can convert the above to JSON, you can use jsPDF or PDFkit to create the PDF. The functionality maps pretty well based upon the limited data you posted, but I have not seen the full structure of Textract as it is still in Beta and I didn't get an invite to the program. Both these projects can use Node to create a server-side solution, but they also work in the Browser.
At the time of this writing, Google Cloud has an OCR component in their Vision - Document Text Detection feature. Unlike Textract, it approaches the task as just reporting what visual elements the document has and creating a comprehensive (and large) data structure that describes what it "sees." Textract, according to Amazon, uses machine learning to organize the data in a more human understandable form that seeks to differentiate the form from the data that constitutes the filled-out part of the form. If you are trying to create a relatively complete PDF, the Google product is well suited. Textract might be too, but I don't know yet.
This repository contains code examples (in Java) showing how you can generate a searchable PDF using AWS Textract. If you are not using Java, you may also deploy it as an AWS Lambda function and then invoke it via the AWS SDK or as a REST API call using AWS API Gateway.
There is a corresponding blog post also available here.
I'm trying to create an ad using the php sdk.
I can create the campaign, targeting, adset, and the creative (which returns a creative_id that I can validate using the graph explorer).
But when I finally run the code to create the ad itself, I get an exception that looks like this:
"error_user_title" => "Missing creative spec"
"error_user_msg" => "No creative spec found for given adgroup."
I just can't find anything referring to this error.
Below is the relevant portion of my code:
$link_data = new AdCreativeLinkData();
$link_data->setData(array(
AdCreativeLinkDataFields::LINK => $route,
AdCreativeLinkDataFields::MESSAGE => $petition_statement,
AdCreativeLinkDataFields::NAME => $banner_title,
AdCreativeLinkDataFields::IMAGE_HASH => $image_hash,
));
$object_story_spec = new AdCreativeObjectStorySpec();
$object_story_spec->setData(array(
AdCreativeObjectStorySpecFields::PAGE_ID => $pageid,
AdCreativeObjectStorySpecFields::INSTAGRAM_ACTOR_ID=>$instagram_id,
AdCreativeObjectStorySpecFields::LINK_DATA=>$link_data
));
$creative = new AdCreative(null,$account_id);
$creative->setData(array(
AdCreativeFields::TITLE => $banner_title,
AdCreativeFields::BODY => $banner_subtitle,
AdCreativeFields::IMAGE_HASH => $image_hash,
AdCreativeFields::OBJECT_TYPE => 'SHARE',
AdCreativeFields::OBJECT_STORY_SPEC=>$object_story_spec
));
$creative->create();
echo 'Creative ID: '.$creative->id . "\n";
$ad = new Ad(null, $account_id);
$ad->setData(array(
AdFields::NAME => $short_name,
AdFields::ADSET_ID => $adset->id,
AdFields::CREATIVE => $creative,
AdFields::TRACKING_SPECS => array(array(
'action.type' => 'offsite_conversion',
'fb_pixel' => $pixel_code,
))
));
$ad->create(array(Ad::STATUS_PARAM_NAME => Ad::STATUS_PAUSED));
Appreciate any help.
I've often said that the only skill you need to be a successful developer is the ability to agonize over a problem for days, read through source code, google it, refactor, rewrite and then realize you forgot something fucking obvious.
AdFields::CREATIVE => $creative,
should read
AdFields::CREATIVE => $creative->id,
But the ability to persist isn't the skill you need. The real skill is to somehow resist the overwhelming urge to chuck your computer out the window and do something productive with your life instead.
After hours of testing it seems Trevor's answer is incorrect. This is the right syntax:
AdFields::CREATIVE => array('creative_id'=>$creative->id)
In my database I store money as an integer, similar to Stripe. For instance 12.99 is stored as 1299. Basically taking the number and dividing by 100.
I'm trying to incorporate this with Yii2 activeForm, specifically using either the MaskInput or MaskMoney widgets. However, I cannot figure out how to configure either widget so that when the value is "1299" it displays as "12.99". So if a person types in "1200" it displays as "12.00".
This is for a simple frontend solution and not backend so I'm not looking for Yii scenarios or behaviors in this question.
I'm not sure if I understood correctly, but this is the closest I've ever got to what you want.
<?php echo \yii\widgets\MaskedInput::widget([
'name' => 'masked-input',
'clientOptions' => [
'alias' => 'decimal',
'digits' => 2,
'digitsOptional' => false,
'radixPoint' => '.',
'groupSeparator' => ',',
'autoGroup' => true,
'removeMaskOnSubmit' => true,
],
]); ?>
The behaviour of the decimal part is what bothers me, but it works as intended.
I am creating google charts to show Google Analytics data from the past 7 days. I have an issue with the X-Axis labels stacking on top of each other when I have certain data (or at least that's all I can tell is different.)
I am generating the API call using this gem: https://github.com/mattetti/googlecharts and I've looked at what each part of the URL is doing and can't find the issue, but I'm sure I'm missing something.
Here is an example of two sites data over the same time period, the first one shows the issue and the second one is a working example:
Here is the URL, these are text encoded for readability, but it has the same issues when switched to simple or extended encoding:

The chxr values were incorrect. The gem was generating them for multiple axes when it should have only been generating them for one. I manually overrode the min, max and step in the gem and it worked.
Here is my code using the gem, first getting the max value from all my data points:
[#visits,#visitors,#new_visits,#organic_searches].each do |array|
array.values.each do |value|
#max_value = value if (value > #max_value)
end
end
# Chart it
chart = Gchart.line(
:title => prop.to_s.upcase + ' Google Analytics - Past 7 Days',
